Aeration Blower Filter and Bearing

The aeration blower check is the inlet filter and the bearing history, with the blower locked out before a guard comes off. The technician writes the as-found reading and compares it with the last one on the asset. Do not change an airflow setpoint from this work order. 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. With the blower locked out, inspect the inlet filter
  2. Check the bearing housing temperature history and the guard
  3. Confirm the discharge valve position matches what operations posted
  4. Do not change an airflow setpoint from this work order
  5. Write unusual noise or heat as a finding

What Skipping It Looks Like

The filter loads, amps climb, and the airflow setpoint moves so the basin 'looks the same'. The round still closes, the number never lands on the asset, and the next person inherits a guess. Do not change an airflow setpoint from this work order.

Setting the interval

Monthly. Unusual heat or noise is a finding. The posted valve position stays. 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. Unusual heat or noise is a finding. The posted valve position stays. 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 1.5 hours 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 filter loads, amps climb, and the airflow setpoint moves so the basin 'looks the same'. The round still closes, the number never lands on the asset, and the next person inherits a guess. Do not change an airflow setpoint from this work order.
