Dust collector annual maintenance checklist
The annual dust collector service is the deep pass: the measurements, cleanings and tests a quarterly round doesn't reach. This checklist keeps the full service on record with the photos that make it defensible later. Work is commonly verified against manufacturer's published instructions. Confirm the edition your authority having jurisdiction has adopted.
The checklist
Every item, and the photo evidence it needs
The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.
Shutdown and lockout
Served machines stopped and their operators told
Operators at every tool the collector serves told of the outage and the machines stopped, since running them without capture puts dust into the room.
No photoFan, airlock and every feeding source locked and tagged
Lock and tag hung under the site's procedure on the fan, rotary valve, any conveyor and the cleaning controller, each tried from its normal control and staying stopped.
Compressed air isolated and pulse header bled down
Supply valve closed and locked, header drained until its gauge reads zero, so no diaphragm can fire while hands are in the plenum.
Dust PPE and entry procedure in place before doors open
Respirator and clothing per the site's dust hazard assessment, hopper emptied first, entry under the site's confined-space procedure where it classifies the collector.
No photo
Filter change
Filters changed and old media inspected
Bags or cartridges replaced with the correct type, old media inspected for holes, caking or channeling that points to a pulse or moisture problem.
Tube sheet, cages and seals inspected on reinstall
Tube sheet clean and flat, cages straight, gaskets and clamps sealing so no dust bypasses the new filters at the seat.
Blowpipes and diaphragm valves inspected
Blowpipes secure and aligned over the filter centers, nozzles clear, diaphragms inspected for tears or hardening, with worn ones replaced.
Internal inspection
Clean-air plenum and housing opened and inspected
Clean side checked for any dust that shouldn't be there, housing and hopper walls inspected for wear-through, corrosion or abrasion at elbows and inlets.
Airlock, dampers and protection devices serviced
Rotary airlock vanes and seals inspected for wear, dampers and blast gates freed and confirmed, explosion-protection hardware confirmed intact and unobstructed.
Explosion vent and isolation device inspection on file
Whichever devices are fitted inspected to the manufacturer: vent panel, seal and fasteners, flap valve swing and seat, chemical isolation by its service provider; report on file.
No photoSpark detection and extinguishing test report on file
Where fitted, detectors and the extinguishing valve tested by the system's service provider, with the monitoring company told first if it reports to the fire alarm.
No photo
Bonding and ductwork
Duct and collector bonding continuity measured
Resistance measured across flex connectors, duct joints and to the collector ground against the site's acceptance value, beyond the quarterly visual check of the straps.
Duct cleanouts or access doors opened and checked for settled dust
Settled dust in horizontal runs flags low transport velocity; dust removed with a vacuum rated for it, the run noted for a balance review, cleanouts or doors resealed.
Return to service
Access doors sealed and locks removed by whoever hung them
Tools and rags out of the plenum and hopper, every access door latched on its gasket, compressed air restored, then locks and tags removed by the people who hung them.
Clean-filter differential pressure recorded as the baseline
Collector restarted with pulse cleaning running, the gauge reading across the new filters photographed and recorded as the baseline next quarter's trend is read against.
What usually sends this back
The failures are almost always the evidence, not the work
- New filters seated without checking the tube sheet or cages, so a gap or bent cage lets dust bleed straight through the fresh filters to the clean side.
- Interior signed off without looking for a leak path, so the pinhole or worn gasket that was passing dust downstream is reinstalled around.
Common questions
6 answers
- What does this dust collector annual checklist cover?
- 15 items across 5 sections, covering shutdown and lockout, filter change, internal inspection, bonding and ductwork, and more. Each item spells out what the person walking the job is actually looking for, not just a box to tick.
- Who should run this inspection?
- The service tech on the annual service, with the collector locked out and offline.
- When in the schedule should this walk happen?
- Once a year, scheduled during a shutdown so filters can be pulled and the clean-air side opened without dust escaping into the space.
- Why do these items ask for a photo?
- 11 of the 15 items call for photo evidence, 14 photos in all. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.
- What most often fails a dust collector annual inspection?
- New filters seated without checking the tube sheet or cages, so a gap or bent cage lets dust bleed straight through the fresh filters to the clean side. Interior signed off without looking for a leak path, so the pinhole or worn gasket that was passing dust downstream is reinstalled around.
- Can I use this checklist in RTI?
- Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper evident audit trail.
Run it with the Photo Gate
A checklist nobody can submit half-finished
Load this list into RTI, stick a QR tag on the area it covers, and the submit button stays locked until every mandatory item is answered and the 14 required photos exist. Approved walks roll into a branded turnover package with a tamper evident record behind every line.
