Optimize Dust Collector Compressed Air Pressure to Balance Filter Life, Efficiency and Airflow
The pressure supplied by the compressed-air system must be high enough to clean the entire length of the bag during the pulse, but not so high that it damages the upper portion of the bag. Insufficient cleaning of the bag may gradually increase pressure drop and reduce the useful bag life.
If the compressed-air pressure is too low, which is usually more common than excessive pressure, it may be caused by wear of the compressor rings, leakage in connections, or excessive draining of the reserve of the compressors by other equipment tied to a common supply line. Additionally, if the pulse valves, air header tanks or connecting pipes on the unit itself have leaks, then the absolute pressure or the effective pressure at the blowpipe will be lower.
If the compressed-air pressure is too low, it may cause excesive wear of the compressor components
For most applications using felted filter media, compressed air at roughly 70 PSI (Per Square Inch) is adequate for proper cleaning of the filter elements. Pressures between 100 and 120 PSI may be recommended for some difficult applications where other options to improve cleaning efficiency are not viable. Operators running their systems at pressures above 100 PSI should first consult a dust collection expert at Baghouse.com for advice and recommendations on how to improve performance.
Compressed air pressures below 70 PSI may be required under special circumstances such as when using cartridges, pleated filter elements or with certain filter medias such as fiberglass. These situations often call for special design and sizing of the dust collector in order to function correctly.
Guidelines for Setting Compressed Air Pressure on a Pulse Jet Baghouse
If filters are not cleaning sufficiently, raising the air pressure may be one of several things to try to improve operation.
The following general guidelines can help you to set the the correct pressure of compressed air for your baghouse:
— Start at 60 PSI and go up as needed by the application. At no point should it go above 100 PSI unless advised to do so by a reputable dust collection systems engineer.
— Pleated filter systems and cartridge systems may use much lower PSI for cleaning depending on the design of the unit and the application (airflow, dust load on filters, how hard the dust is to pulse off, moisture problems, etc.)
— If filters are not cleaning sufficiently, raising the air pressure may be one of several things to try to improve operation. However, it alone will not solve the problem in most cases. Often, fixing other problems such as high can/interstitial velocity, will improve things so that you can actually lower the PSI and have better cleaning.

While many facilities often choose to install replacement filters using in-house labor, usually to keep costs down, it is not always the best idea to simply assume that using in-house labor is the best option. Here’s why relying solely on your maintenance staff for baghouse filter installation may not be the best option.
The Risks of Using In-House Labor
Improperly installing the bags (not sealing them correctly, improper tension, etc.) can lead to leaks and early failure of the bags
When workers without specialized training attempt to service a baghouse, several issues can arise. For example, filter bags, particularly those with PTFE membranes, are fragile and require careful handling. Untrained personnel can easily damage the bags during installation, leading to early failure or leaks. Furthermore, incorrect installation techniques, such as failing to properly seal the bags or applying incorrect tension, can result in compromised system performance and costly downtime.
In addition to potential damage, in-house workers might not be familiar with the unique safety hazards associated with baghouses. This can lead to injuries, further increasing costs for the facility.
Efficiency Concerns
Even if the installation is completed without incident, it usually takes much longer for in-house labor to replace filters compared to a trained baghouse service team. Experienced technicians understand the design and operation of various baghouse types and can perform replacements safely and efficiently. When in-house teams handle filter changeouts, it often leads to delays, increased labor costs, and extended facility downtime. These delays are especially costly when mistakes are made during installation, requiring additional resources later to fix the problems.
For instance, one facility chose to have its regular maintenance workers replace filters in 18 compartments, each containing 200 reverse-air filters with springs and chains. The in-house team took an average of three days to replace the filters in one compartment, often making mistakes like improperly sealed bags or incorrect tension. In contrast, a professional crew completed the same work in just four compartments per day while also addressing additional maintenance tasks such as scraping rust scale from walls and performing leak tests.
Benefits of Hiring Professional Baghouse Technicians
Professional crews are trained to recognize underlying problems that may go unnoticed by in-house teams, such as broken supports of blowpipes, as seen here
Hiring expert Baghouse.com technicians can save facilities time, money, and resources. Professional crews are trained to recognize underlying problems that may go unnoticed by in-house teams, such as warped metal, failing welds, moisture issues, and abrasion damage. These early detections can prevent more serious issues down the line.
Conclusión
While using in-house labor to install baghouse filters may appear to be a cost-effective solution, the risks of improper installation, safety hazards, and inefficiencies can quickly outweigh any potential savings. In many cases, outsourcing this task to professionals pays for itself through increased efficiency and reduced risk.

All industrial baghouse systems are designed with various cleaning methods in order to ensure correct operation and longevity of the baghouse filter.
As the bag flexes, the dust cake (built up dust on surface) fractures falls into the hopper below.
Today, the most common cleaning method used in industrial dust collectors is pulse jet or reverse jet cleaning. These methods involve removing the dust from the bag filters using a blast of compressed air. The air blast creates a shock wave that causes the bag to flex or expand as the shock wave travels down the bag.
However for trouble and maintenance free operation, it is extremely important that the compressed air used in the system is clean, polvo precapa and at the correct presión. In this article we will concentrate on the importance of dry and clean compressed air. A discussion on the importance of proper air pressure will be covered in a another article.
Clean, Dry and Oil Free Compressed Air
Dirt, rust, and scale can prevent diaphragm valves from operating properly. Moisture can cause valves to freeze in cold weather.
Moisture and oil can also cause deterioration of the valve diaphragms, and if the interior of the filter bags become coated with moisture and/or oil, eventual blinding of the filter media will occur. Blinding of the filter material occurs when the filters become so impregnated with dust in the depths of the fabric that you cannot clean them 100% anymore and the airflow through them will never go back down, resulting in premature failure of the baghouse filters.
A Liquid Moisture Trap (automatic moisture drain) must be installed on the compressed air receiver.
How to ensure the Compressed Air is:
Clean
In order to trap small amounts of dirt, rust and scale, a small dirt leg is installed at the point where the air line connects to the compressed air header. In situations where large amounts of dirty rust and scale are present, and inline filter or a centrifugal separator is required.
Dry
A Liquid Moisture Trap (automatic moisture drain) must be installed on the compressed air receiver.
There are a number of solutions to ensure that the Compressed air remains dry. For example a Liquid Moisture Trap (automatic moisture drain) must be installed on the compressed air receiver. These automatic drains come in a variety of float, piston, and pilot operated types. When small amounts of moisture are present it can be handled by inline air filters with automatic drains. For large amounts of moisture, a centrifugal separator and chemical dryer may be required. For more specific situations, for example climate and indoor temperatures, other methods are used to ensure the compressed air remains dry.
Much of the above mentioned equipment used to remove moisture can also be used to remove oil and oil mist. For installations where oil and oil mist are the major problem, inline filters are available that use desiccant adsorptive elements or packed beds of an oil absorbing granular organic polymer.
Conclusión
During regular operation, Pulse Jet Industrial filtering systems do not stop the flow of dirty air into the baghouse and it is the only true “online cleaning” method.
Bag cleaning cycles are initiated to keep the overall pressure drop across the baghouse within the designed range. Therefore the importance of clean, dry, oil free compressed air cannot be over emphasized. However another important factor to take into consideration is the pressure of the compressed air. This will be discussed in an upcoming article.
