A dust collector handling metal fines is a vessel containing a combustible dust cloud by design. Everything about its maintenance is deflagration control: intact filter media so dust does not carry into the clean side, working pulse-clean so the hopper does not accumulate, and unobstructed explosion vents so that if it does ignite, the pressure goes somewhere survivable. Aluminium and magnesium fines raise this from serious to severe.
The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

Capture velocity falls first, so fume and dust escape into the shop and the exposure problem moves to the breathing zone. Meanwhile dust builds in ductwork and the hopper. Blocked or painted-over vent panels are the detail that turns a contained deflagration into a structural one — and they are blocked by ordinary housekeeping and storage far more often than by anything dramatic.
Quarterly, and treat differential pressure as continuous monitoring rather than a quarterly reading. Combustible metal dust warrants monthly. Any change in the material being processed should trigger an immediate review — the collector was sized and vented for a specific dust.
This procedure — and every other PM for your industry — is already built into ChatterFix. Pick your industry and it lands on the right equipment, on the right interval, in about three minutes.
