Where each walk sits in the schedule

  1. 01quarterly

    Dust collector quarterly maintenance checklist

    Every quarter, and more often on a heavily loaded baghouse, since a blinding filter is the first thing that quietly kills capture at the tools.

    Run by: The maintenance tech on the quarterly round for the collection system.

  2. 02annual

    Dust collector annual maintenance checklist

    Once a year, scheduled during a shutdown so filters can be pulled and the clean-air side opened without dust escaping into the space.

    Run by: The service tech on the annual service, with the collector locked out and offline.

What most often fails on a dust collector

  • Rising filter differential pressure ignored until capture at the pickups drops off and dust starts settling around the machines the collector serves.
  • Pulse-clean assumed working because the compressor is running, when a stuck diaphragm valve or low header pressure means half the rows aren't actually pulsing.
  • Rotary airlock left bridging or leaking, so the hopper packs out and dust backs up into the clean-air side instead of discharging.
  • 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 run these checklists in RTI?
Yes. Start a free RTI workspace and load any of the 2 lists (30 items in total). The Photo Gate holds the submit button until every mandatory item is answered and its photos are attached, and approved inspections roll into a branded turnover package with a tamper evident audit trail.

Run these lists with the Photo Gate.

Tag one area, scan it, and the submit stays locked until the photos exist.
