Below is a list of dust collector maintenance items and when to check them, depending on the system’s design:

Daily Checklist

• — Check differential pressure.
• — Observe exhaust stack (or check emissions monitoring system).
• — Operate damper valves.
• — Confirm that dust is being removed from system via dust discharge system.
• — Confirm cleaning system is operating correctly and set to the correct cleaning sequence.
• — Check compressed-air lines, including line filters and dryers.
• — Verify accuracy of temperature-indicating equipment.

Monthly Checklist

• — Inspect fans for corrosion and material buildup.
• — Check drive belts for wear and tension.

• — Inspect and lubricate appropriate items.

• — Spot check for bag leaks.
• — Check hoses and clamps.

• — Check accuracy of indicating equipment.
• — Inspect housing for corrosion.
• — Walk through system, listening for proper operation.
• — Check for unusual occurrences in process.
• — Observe control panel indicators.
• — Check compressed-air pressure.
• — Check differential pressure-indicating equipment for plugged lines.
• — Blow out any dust from differential pressure lines and verify gauges are in good condition and not fouled.

Quarterly Checklist

• — Inspect baffle plate for wear.
• — Inspect bags thoroughly.
• — Check duct for dust buildup.
• — Observe damper valves for proper seating.
• — Check gaskets on doors.
• — Inspect paint, insulation, etc.
• — Check screw conveyor for wear or abrasion.
• — Check that valves are opening and closing properly in bag-cleaning sequence.

Annual Checklist

• — Check fan belts.

• — Check welds.

• — Inspect hopper for wear (see full list in Appendix)
• — Evaluate filter performance (DP, emissions, failed bags, etc.) and schedule filter changeout as needed.
• — Ensure plant has one full set of filters on hand for emergencies. IF possible/necessary, also stock one full set of cages or a small number of spare cages for maintenance use.
