5 Benefits of a Well-Maintained Dust Collection System

In the world of industrial operations, maintaining your dust collectors in top condition can consume lots of time and resources. But investing in regular maintenance yields many advantages for productivity, product quality, employee health, compliance with safety standards, and equipment longevity:

1. Boost Productivity

Excessive dust accumulation inside your facilities or on industrial equipment poses a silent threat to productivity.  If your dust collection system is underperforming due to prolonged wear and tear or if your dust collector is inadequate or undersized, it poses a significant risk to your entire operation. Filter leaks and other maintenance issues that go unchecked could lead to an unexpected plant shutdown, disrupting operations for days to weeks or more.

Filter leaks and other maintenance issues that go unchecked could lead to an unexpected plant shutdown, disrupting operations for days to weeks or more.

Additionally, even minor maintenance issues can have unseen impacts on your operations. Take for example a dust collection duct that slowly accumulates dust build-up. The airflow at dust pickups slowly reduces over time and fugitive dust slowly increases, costing more and more time spent on housekeeping and cleanup. Alternatively, addressing the issue with regular duct inspection and cleanouts will keep your workforce productively working on shipping product.

2. Increase Product Quality

For many manufacturing facilities, dust in the air can mean dust on their products. A robust dust collection system acts as a guardian, efficiently capturing and eliminating dust particles from the air. This not only enhances the quality of finished goods but also ensures consistency in production.

Any maintenance issue with your dust collector, fan, ductwork, cleaning system, or controls ultimately results in more unwanted dust in your facility, increasing the risk of dust on and in your products.

3. Enhance Health & Safety Standards

Industries dealing with hazardous materials emit contaminants that may pose serious health risks to employees. Inhalation of these particles can lead to both short-term and long-term health issues. For example, silica dust may expose workers to silicosis, and wood processing may expose workers to carcinogenic dust.

A well-maintained dust collection system plays a critical role in removing hazardous dust, safeguarding the comfort and long-term health of your workforce. Additionally, it mitigates the risk of fire or explosion, especially in industries susceptible to combustible dust.

4 Requirements for a Combustible Dust Explosion

  • — Oxygen
  • — Enclosed space (ductwork or a baghouse)
  • — Ignition source (spark or smoldering dust)
  • — Combustible dust dispersed at the right concentration level 

4. Preserve Equipment

Manufacturing machinery is a substantial investment, and its lifespan can be significantly shortened by the accumulation of dust and debris. Dust settling on sensitive surfaces (such as computers, control boards, mechanical parts, etc.) can lead to malfunctions, resulting in frequent and costly maintenance.

A proactive approach to dust collection not only ensures the longevity of your equipment but also reduces the need for extensive and unplanned repairs.

5. Enhance Production Through Strategic Maintenance

Unlike reactive or routine maintenance, which focuses on fixing issues as they arise, strategic maintenance (also known as “planned maintenance” or “total preventive maintenance or TPM”) involves a thoughtful, long-term perspective. The first step in implementing strategic maintenance at your facility is to plan periodic inspections following a maintenance checklist tailored to your specific system.

Frequently Asked Maintenance Questions

How can I know if the filters are working correctly?

The main signs to know if your filters are in good condition or if they need to be replaced are whether they can be cleaned effectively or not by the baghouse, or if they start leaking. Click here to read more about filter service life.

 

How often should I do a filter changeout?

Baghouse filters have an average service life of 1-3 years in most applications. Some can go beyond that without major increases in emissions, while others may last less than a year in more difficult applications. The two main reasons to replace baghouse filters at the end of their life are (1) because blinded filters will begin to have higher and higher emissions (even if there are no holes) and (2) old filters have higher differential pressure (i.e. pressure drop), which decreases the airflow through the system, causing cascading effects of reduced dust collection at pickup point (fugitive dust emissions) and dust buildup in the ductwork.

 

Can we delegate the filter changeout to our in-house maintenance department?

Of course you can! But you want to make sure they are properly qualified for the task. With dust collection training from Baghouse.com, your maintenance technicians, maintenance planners, engineers, operators and reliability staff will be able to keep your systems running at maximum efficiency, troubleshoot any problems that may arise, and optimize the systems to meet the demands of production.

Purchasing a Dust Collector: 6 Factors to Keep in Mind

  • If you’re in the market for a dust collector, whether it’s a new purchase or an upgrade for your facility, it’s essential to make an informed decision. A dust collector is a crucial component for maintaining air quality and safety compliance in various industries.

To ensure you get the right dust collector for your specific needs, consider these six key factors:

1. Dust Control Requirements

Different processes generate various types of dust, from wood chips to welding fumes or grain dust. It’s vital to not only recognize the type of dust you generate but also how your processes create it. How much dust is generated by the process? Is this dust hazardous or does it require special handling? Are there regulatory standards for air quality that you need to meet?

In response to these challenges, two primary dust collection systems have proven effective: baghouse-style dust collectors and bin vents. These systems offer reliable solutions for grain dust control, each with its unique advantages.

2. Customization Options

Dust collectors are not one-size-fits-all solutions. The space constraints of your facility may require customizations in terms of height, footprint, or additional features like discharge devices, monitoring equipment, or fire and explosion mitigation tools.

Other common custom features include:

  1. Rotary airlocks, screw conveyers, or other special dust discharge equipment
  2. Special construction materials like stainless steel for food applications
  3. Customer controls including integrated motor starters, timer boards, differential pressure gauges, or outputs to connect to control systems
  4. Special sizing for very light dusts or restricted spaces

3. Complete System Design

New baghouse system

The type of dust and your operational needs will determine the most suitable dust collector. In the cases where dust is hard to collect due to being too fine or sticky, you should obtain a dust collector that is equipped to capture it effectively. Another instance could be if your industry demands complying to food-grade standards.

Additionally, different dust collector styles are more suited than others for certain applications. Generally, cartridge collectors work best for light dust loads and fine dusts at lower temps, but perform poorly with heavy dust loading, irregularly-shaped dusts, or sticky dusts. Baghouses on the other hand, are able to work in a wide range of applications. Many companies will only offer you a single style and try to convince you it can do more with less so it appears to be the cheapest bid, regardless of how well it will perform later.

Finally, if your dust is hazardous or explosive, it’s crucial to obtain a specialized system (collector, ductwork and safety devices) designed to comply with NFPA regulations.

4. Installation Simplification

Baghouse installation by baghouse.com personnel

The ease of installation depends on the size of the dust collector and its location. Smaller collectors located close to the dust source may eliminate the need for extensive ductwork, simplifying installation. Understanding your processes, localizing dust collection, and minimizing collector size can streamline installation. It is critical to work with an expert in dust collection systems who can foresee potential installation issues and address them early on to ensure a smooth install.

5. Long-Term Value for Your Investment

Your investment in a dust collector goes beyond the initial purchase. Think about the operational costs for the entire lifecycle of the system. Factors like replacement filters, downtime due to maintenance, and energy consumption need to be analyzed closely. Evaluating collector style, location, and design can help you make a cost-effective choice. Watch video: Intro Guide to Sizing and Designing Your Baghouse

Grain Dust Collection Systems Overview

Grain dust collection is a paramount concern within the grain and seed industry, given the frequent occurrence of grain dust fires and explosions. So prevalent is this issue that OSHA has established its own combustible dust rule specific to agricultural dust. Failures in grain dust control not only compromise workplace safety but tragically result in injuries and fatalities.

The Varied Nature of Grain and Seed Dust

Grain and seed dust come in diverse sizes and textures, making effective control of dust a multifaceted challenge.

The grain dust can range from abrasive and sticky to fine and volatile. Moreover, grain processing facilities encompass a multitude of machines and processes, all of which require meticulous dust control to comply with OSHA and NFPA standards.

Processes within the grain and seed industry that are particularly prone to generating problematic dust include:

  1. Conveyor belts and transport systems
  2. Bucket elevators
  3. Transfer points
  4. Hammer mills
  5. Bins and silos
  6. Blenders and mixers
  7. Truck and rail loading and unloading

Grain dust sources in agriculture such as: truck loading, conveyor belts and harvesting

 

In response to these challenges, two primary dust collection systems have proven effective: baghouse-style dust collectors and bin vents. These systems offer reliable solutions for grain dust control, each with its unique advantages.

Recommended Equipment for Grain Dust Control

  • Baghouse Dust Collectors: Unlike cartridge collectors which are very efficient but require uniform dust grain size, light loading, and a narrow range of dust types, a baghouse is a robust collector that can operate with a larger selection of filter media, and generally suffers from fewer problems with varying grain size and loading. A suction-side fan is typical, with a network of ductwork connecting the central dust collector to pickup points on conveyer belts, silos, transfer and loadout points, and other dust sources.
  • Bin Vents: A bin vent is a specialty piece of dust collection equipment designed for silos and storage bins. As product is loaded into a silo, via pneumatic transfer, gravity chute, etc., pressure is created in the enclosure. A bin vent is used to allow this pressure to vent to the outside air without spewing dust into the air. Bin vents may have a fan to generate negative pressure, or they may operate as a passive vent with no fan. In either case, they are filters that operate according to the same principals as a baghouse or other dust collector.

Possible Additional Equipment

Grain dust, due to its extreme combustibility, presents a substantial fire and explosion risk across all grain-handling applications. Dust control measures are vital in preventing accidents that can lead to injuries, facility damage, and even fatalities. Fires within grain processing facilities have been known to inflict significant harm on structures and equipment.

Grain silos with a dust collection system

Given the inherent risks, it is essential to consider a highly effective grain dust collection system as a mandatory component of any grain and seed processing facility. Safety standards unequivocally dictate that all systems must be safeguarded against fire and explosion hazards. This is not an area where cost-cutting is prudent; investing in a properly designed system is an imperative step towards a safer, more secure working environment.

How to Select the Right Dust Collector Rotary Valve

Dust collector rotary valves, also known as rotary airlocks or rotary feeders, are essential components in many industrial processes that involve the handling of bulk materials and are very commonly used in dust collection systems. These valves play a crucial role in controlling the flow of material, preventing air and pressure loss, and ensuring minimal product loss during processing. Selecting the right dust collector rotary valve is of utmost importance to maintain system efficiency, safety, and product integrity. In this article, we’ll delve into the different types of rotary valves and the key considerations for selecting the right one for your specific application.

Rotary Valve

Understanding Rotary Valves

Rotary valves are mechanical devices that facilitate the transition of materials from pressurized environments, such as dust collectors, to unpressurized points, like storage bins or drums. They come in various types, sizes, and materials to suit different industrial applications.

Types of Rotary Valves

  • Drop-Through Rotary Valve: In drop-through valves, product feeds into an inlet at the top, typically from a gravity-fed hopper, and exits through an outlet below. These valves are often used in applications where the primary function is to maintain air pressure differentials.
  • Convey Through (Blowing Seals) Rotary Valves: In convey-through valves, product enters the inlet and is directly fed into a pneumatic convey line connected to ports on the bottom sides of the housing end covers. These are more suitable for applications where height limitations exist, and the valve feeds a pneumatic conveyor directly.

Choosing the Right Rotary Valve

Selecting the right rotary valve depends on several critical factors:

1. Application Type:

  • Airlocks: Used in applications where maintaining pressure differentials is crucial. They allow material to flow between different pressure zones and are commonly found in cyclone and baghouse outlets.
  • Feeders: These valves control the rate at which material flows through the valve by metering the bulk powder material’s flow. They are suitable for low-pressure or gravity-fed applications, such as filling packaging machines.
  • Airlock Feeders: Combining the functions of airlocks and feeders, these valves are versatile and can be used for feeding pneumatic conveyors or moving products in and out of pressure and vacuum receivers.

2. Materials of Construction:

The choice of materials for the housing, rotor, drive, and accessories is crucial to match the requirements of your product and the operating environment. For example, some applications may require stainless steel for its resistance to chemicals, while others may need cast iron or chrome-plated cast iron for durability.

Adjustable rotors allow for tips to be adjusted to account for wear, and flex tip rotors are designed to maintain an airtight seal while preventing material jams. These are just a couple examples of the type of material and design options available.

3. Ease of Cleaning:

For applications where frequent cleaning is necessary, choose a rotary valve designed for easy disassembly. Look for valves that facilitate access to product contact surfaces for cleaning. Hygienic applications should ensure the valve’s surface finish, seals, and construction meet regulatory standards.

Typically, open end rotors are easier to clean and maintain. These are often used with lighter or finer materials, to minimize the risk of material becoming trapped in the space between the endplates and rotor disc.

5. Pressure:

The pressure of your conveying system is a key determinant of the required valve durability. Dilute phase pneumatic conveying systems typically operate between 4 and 8 PSI, while dense phase systems operate over 15 PSI. Valves for high-pressure or vacuum applications need to be designed to withstand the conditions, possibly requiring additional venting systems to prevent air leakage.

6. Temperature:

Consider the operating temperature, as extreme heat or cold can impact the choice of materials, rotor design, and airlock capabilities of the valve. Ensure the selected valve can withstand the temperature conditions of your application.

Selecting the right dust collector rotary valve is a critical decision for maintaining the efficiency and safety of your industrial processes.

By considering the type of valve, materials of construction, ease of cleaning, explosion protection, pressure, and temperature, you can make an informed choice that ensures optimal performance, minimal product loss, and a safe working environment. Collaborating with experts in this field such as Baghouse.com can be invaluable in making the right selection for your specific application.

The Role of Filter Cages

Filter cages might seem quite simple components, but they are essential for the proper functioning of your dust collection system. When filter bags don’t fit snugly onto the cages or when cages are not replaced when needed, it can compromise the entire system. Neglected filter bag cages are often the root cause of many operational problems in industrial settings.

Cage Types

The purpose of a baghouse cage is to provide support for filter bags to stay open during the dust collection cycle.

 

 

Common Cage Styles

Common baghouse cage styles include rolled top (top load baghouses) and split collar (bottom load baghouses). Options include galvanized steel, stainless steel, or epoxy coated. Cages can also have integral or drop-in venturi for improved bag cleaning.

One key feature is the precise fit between the filter bags and the cage, ensuring proper adhesion and a long service life. Quality filter cages are built to withstand cleaning cycles, bag changes, abrasive materials, high temperatures and many other environmental conditions they might encounter.

Additionally, filter cages should withstand the pressure exerted by the filter bag during the particulate collection cycle. They are also engineered to provide uniform support along the entire length of the filter cloth.

Regardless of design, each cage should adhere consistently to its specifications. This includes maintaining the correct diameter, total length, and other tolerances. The technologies we employ at Baghouse.com ensure your cages are made to spec, ensuring a proper fit between the filter bag and the cages and resulting in optimal cleaning performance. Our dust collector cages can be made to fit existing collectors from any baghouse manufacturers such as Astek, Gencor, Flexkleen, Mikropul, Wheelabrator, etc. We can also manufacture uncommon and specialized cage designs as required.

How Do Dust and Fume Collection Systems Work?

Dust and fume collection systems are indispensable in various industries, such as processes involving exhaust fumes from welding, sanding, grinding, spraying. Does your plant have any of these processes? If so, you must be interested in ensuring not only cleaner, safer workplaces but also compliance with environmental regulations. Among these systems, there’s one lesser-known hero: the ambient air collection system. In this article, we’ll explore how these systems function and their advantages.

Understanding Ambient Air Collection

At its core, an ambient air collection system is a type of dust and fume collection system. It operates by efficiently removing airborne particles from the atmosphere, making it an ideal choice for certain fabricating environments.

Cartridge collectors are commonly recommended for ambient systems due to their efficiency and compact design. These collectors use densely pleated filter cartridges with a high surface area, capable of handling substantial airflow. They excel at capturing even very fine fumes, up to MERV* 16, ensuring clean air. 

*MERV stands for “Minimum Efficiency Reporting Value.” It is a standardized measurement rating used to evaluate the efficiency of air filters in removing particles from the air as it passes through them. The MERV rating typically ranges from 1 to 16, with higher values indicating greater filtration efficiency. A higher MERV rating means the filter can capture smaller particles, including dust, fine fumes and other airborne contaminants.

The Difference: Ambient vs. Source-Capture

Ambient collection stands in contrast to source-capture systems, which rely on localized collection points like weld arms or fume hoods. Instead of capturing pollutants at specific spots, an ambient system continually exchanges all the air in a building or designated area.

Ambient systems offer several advantages over localized approaches:

  • Efficiency: Ambient systems are efficient, requiring less ductwork and power compared to localized systems with multiple capture points.
  • Cleaner Air: By removing dirty air from the entire workspace and returning it as clean, filtered air, ambient systems maintain overall air quality, even managing fugitive dust or fumes from portable sources.

    Modular Ambient Systems

    In variable production environments, a modular ambient dust collection system can be a smart choice. This approach involves using multiple smaller collectors instead of one large central system. It’s particularly beneficial for facilities with fluctuating production levels or plans for expansion.

    The experts at Baghouse.com can assist you in determining whether a modular or central ambient system is the right fit for your facility, considering factors like your current and future space usage and budget.

    Exploring Optional Functions in Fume Extraction Systems

    When considering fume extraction systems, you’ll encounter various optional features that can enhance their performance. These include:

    • Automatic Start-Stop Functionality: The automatic start-stop feature ensures that the fume extraction system operates precisely when needed. It activates as soon as the welding gun initiates an arc and includes a brief delay of usually 3 to 10 seconds after welding ceases. This thoughtful design not only conserves energy by preventing unnecessary blower operation but also contributes to lower maintenance costs and a quieter shop environment. Read more about Welding Safety Precautions.
    • Power Adjustment Capability: The power adjustment feature allows you to fine-tune the static pressure of your fume extraction system, aligning it with the specific parameters of your welding machine. Lowering the power not only reduces noise but also minimizes energy consumption. Additionally, it proves valuable in addressing rare occurrences like weld porosity or gas turbulence during welding. These events, while infrequent, are efficiently managed with this feature, ensuring your system’s readiness even when equipped with high-performance fume extraction equipment and welding guns.
    • Automatic Cleaning Functionality: Automatic cleaning is a smart feature that enables the system to self-clean the filter when a certain level of dust accumulates. This process can be based on a timer or triggered by monitoring the actual static pressure against the preset power of the unit. Importantly, this self-cleaning process occurs seamlessly while the welder continues to work.
    • Shunt Alarms: Shunt alarms provide clear signals, often through lights or gauges, indicating the need to replace the filter. This feature can be integrated into a fume extraction system equipped with automatic cleaning or used with systems featuring replaceable filters, ensuring you stay aware of filter maintenance requirements.

It is also worth considering if you have an existing concrete pad, or if one must be poured to support the weight of your collector and fan. Watch the video: Intro Guide to Sizing and Design Your Baghouse.

3. Emissions Requirements: Navigating Legal Waters

Specific emissions regulations might apply based on your application. Emission limits differ by state and are expressed as efficiency percentages for cartridge collectors or emission limits (like lbs/hr or gr/dscf) for baghouses. These limits may impact the filter media required for your system, as well as the need for after-filters or additional equipemnt. Read more about regulatory requirements and compliance.

4. Volume: Sizing for Efficiency

Accurate airflow measurement is crucial for effective dust collection. Wrong volumes can disrupt production, air quality, and increase energy costs. 

Airflow is measured in cubic feet per minute (CFM), showing how much air moves per minute from a space.

Variables for Volume Calculation:

  • Dust collection method
  • Duct size
  • Workspace volume

Getting the airflow right ensures long-term collector efficiency. Want to know more? Read the following article: Why You Need to Properly Size Your Baghouse System.

5. Air-to-Cloth Ratio: Striking the Balance

The air-to-cloth ratio measures airflow efficiency through filter media. The right balance ensures optimal filtration.

Why Air-to-Cloth Ratio Matters:

  • Lower ratio for efficient dust removal
  • Higher ratio leads to increased energy costs and decreased suction

Calculating this ratio helps size the collector accurately, preventing pressure drops and maintaining air velocity. How to Select the Right Differential Pressure for My System?

Baghouse Styles: Picking Your System

The three most common baghouse styles are pulse jet, reverse air, and shaker style. Each has its advantages and disadvantages. The right choice depends on factors like space, maintenance needs, and filtration requirements.

  • Pulse Jet: Bags cleaned while operating, low maintenance, flexible sizing.
  • Reverse Air: Gentle cleaning, divided sections, custom bag design.
  • Shaker Style: Easy operation, low initial cost, shaker mechanism for cleaning.

Dust Collector Design for Easy Maintenance

Choosing design features that simplify maintenance is a smart long-term investment. Things to look for:

  • On-demand filter cleaning for efficiency and durability (not all control panels offer this option)
  • Modular design for expansion and accessibility
  • Quick access filter covers
  • Standard filter sizes for cost-effective replacements

Combustible Dust Safety Equipment

Safety is top priority, especially with combustible dust, and there are specific equipment requirements for systems handling combustible dust. To ensure your system is safe and compliant, take the following steps:

Tailored Dust Collection Design

Each dust collection application is unique, needing a comprehensive approach. Partnering with an experienced dust collection design and engineering companies like Baghouse.com, ensures efficient and effective systems designed for your facility.

In conclusion, budgeting for industrial dust collection systems goes beyond finances. It’s an investment in health, safety, and efficiency. By considering dust properties, space, emissions, volume, and air-to-cloth ratio, while prioritizing maintenance and safety, you can build a system that’s cost-effective and high-performing. Remember, a well-designed system not only saves money but also ensures a cleaner, safer, and more productive work environment.

Top 8 Mistakes to Avoid When Designing a Dust Collection System

You’ve invested in high-efficiency equipment and tools for your industry, but is your dust extraction system working at peak efficiency or is there waste in your system – wasted time, efficiency, or cost? In this article, we’ll explore the most common mistakes when designing dust extraction and collection systems and how to avoid them. A well-designed system not only ensures a clean and safe workspace but also maximizes the lifespan of your equipment.

Mistake #1: Incorrect Duct Diameters

Mistake: Using duct diameters that are either too small or excessively large can lead to problems. Undersize diameter ducts can quickly become clogged, or wear prematurely due to excess dust velocity. Oversize ducts reduce airflow velocity, which may lead to dust settling and clogging up your system.

Solution: Calculate the appropriate duct diameter based on your system’s needs to maintain optimal performance. You should know the minimum carrying velocity of your dust type, and pick a duct size to match the required air flow (CFM) for your dust. If you need assistance sizing your system, please watch this video Watch the video: Intro Guide to Sizing and Design Your Baghouse.

  • Start by understanding the required velocity for your dust and the CFM – then pick a duct diameter to match.

Mistake #2: Using Straight Tees

Mistake: Installing equal (straight) tees can lead to clogs, especially when dealing with soft and fine dust particles. These sharp corners cause turbulent flow, resulting in static pressure loss, and areas of low flow where dust will pile up and clog your system.

Duct union examples

The tee joint on the right is very inefficient; the 45-degree union fitting on the right is a much better design.

Solution: Opt for reducing tees, Y-pieces, or lateral tees to ensure smoother airflow and prevent clogging.

Mistake #3: Using Short Radius Elbows

Mistake: Using short radius elbows can disrupt airflow and greatly increase static pressure drop, similar to the tee joints mentioned above.

This sharp elbow will result in a large static pressure drop.

Solution: Use larger radius elbows (1.5D is standard) to maintain smooth airflow throughout your system and ensure you have adequate static pressure at your pickups.

Mistake #4: Accumulating Fittings Near Equipment

Mistake: Placing elements like dampers, bends, tees, and reducers too close to equipment can hinder proper airflow and reduce system efficiency. Remember, velocity is key in keeping dust airborne – disruptions in airflow slow down the dust, and your system must expend energy to speed it back up after a sharp elbow, etc. If that elbow is right next to your pickup, there is insufficient “runway” to gain sufficient velocity and laminar airflow – resulting in uneven or reduced suction at your pickups!

Solution: Maintain a minimum distance of 2.5 times the nominal duct diameter between airflow-disrupting elements and your pickups to ensure the system operates efficiently (even better is to remove or reduce these elements altogether!)

Mistake #5: Overuse of Flexible Ducting/Hoses

Mistake: Flex hose is very convenient and easy to install, and is often used to connect the last few feet of ductwork to your pickups. However, they are extremely “expensive” in terms of static pressure loss. Excessive use of flex hose can create unnecessary airflow resistance (up to 3X that of a standard duct), significantly reducing system efficiency.

Solution: Limit the use of flexible hoses to the absolute minimum required.

Mistake #6: Using Incorrect Duct Materials:

Mistake: Choosing the wrong material for your duct system (like plastic pipes instead of steel) can be dangerous and lead to explosion risks, very early wear and failure, and other issues.

Rolled lip steel duct

Rolled lip, clamp-together steel duct is standard for dust collection systems.

Solution: Prioritize safety by using metal duct with smooth inner walls to minimize resistance and ensure unhindered airflow. When in doubt, contact an expert to size and select ductwork for your dust collection system.

Mistake #7: Excessively Long Duct Runs

Mistake: Designing excessively long duct runs results in large static pressure drops across the system, meaning that the suction your fan generates isn’t available where it’s needed at the pickups. It’s all being lost in resistance across the long duct segments.

Solution: Install shorter main ducts with lateral discharge branches to individual machines for improved airflow and better static pressure where you need it.

Mistake #8: Incorrect Use of Gates and Dampers:

Manual cut-off gate

Manual cut-off gates are useful, but should be used in alignment with your system design.

Mistake: Incorrectly using cut-offs (also referred to as blast gates or dampers) in your system can lead to system imbalances (too much/too little air flow and velocity where you needed) and dust accumulation and blockages, as well as incorrect static pressure at your pickups.

Solution: If you plan to use manual gates to control flow (to turn specific equipment on/off, for example) ensure that is taken into account in the system design. Modifying your dust collection system then periodically “balancing” it to correct issues, although commonly practiced, is very inefficient and will result in sub-optimal efficiency. Generally blast gates should be fully open or fully closed. If balancing is required, contact an expert to help you with your system.
