Paint quality is airflow. Booth balance controls how overspray is carried away from the part, and as filters load, face velocity falls and the pressure relationship between the booth and the surrounding plant inverts. Dirt gets drawn in, overspray settles back onto wet film, and the defect rate climbs. The same loading also drives solvent concentration up, which is a fire and exposure question rather than a cosmetic one.
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.

Dirt inclusion and orange peel rise, and the response is almost always to blame the paint, the gun or the sprayer. Rework and rejects climb across every job in the booth. On the safety side, a booth running under specified airflow is accumulating solvent vapour in an enclosure full of ignition-capable equipment.
Monthly for filters and balance in a production booth; heavy solids or high duty push it to fortnightly. Differential pressure is the honest trigger — record it each time and let the loading curve set the schedule rather than the calendar.
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.
