Dust Collector Differential and Fan

The dust collector check records the differential on the installed gauge and listens to the fan from outside the housing. The technician writes the as-found reading and compares it with the last one on the asset. Do not open the collector housing or bypass the collector. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

The Procedure

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.

  1. Record the differential on the installed gauge
  2. Inspect the fan guard and listen for unusual noise from outside the housing
  3. Confirm the hopper access is closed and labeled
  4. Do not open the collector housing or bypass the collector
  5. A high differential goes to the site's dust-collector procedure

Why This PM Exists

The dust collector check records the differential on the installed gauge and listens to the fan from outside the housing. The technician writes the as-found reading and compares it with the last one on the asset. Do not open the collector housing or bypass the collector. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

What Skipping It Looks Like

The differential is high, the bypass opens 'until the filters arrive', and the gauge reading never gets written. The round still closes, the number never lands on the asset, and the next person inherits a guess. Do not open the collector housing or bypass the collector.

Setting the interval

Monthly. A high differential goes to the site's dust-collector procedure. An as-found reading outside the limit the site already published is a finding. It does not become a new setpoint on this work order.

Common Questions

How often should this PM run?
Monthly. Monthly. A high differential goes to the site's dust-collector procedure. An as-found reading outside the limit the site already published is a finding. It does not become a new setpoint on this work order.
How long does it take?
Budget about 1.0 hour for a technician working to the standard procedure. ChatterFix uses that estimate for capacity planning, then learns your plant's actual time from completed work orders.
What happens if we skip it?
The differential is high, the bypass opens 'until the filters arrive', and the gauge reading never gets written. The round still closes, the number never lands on the asset, and the next person inherits a guess. Do not open the collector housing or bypass the collector.
