Booth pressure too negative (too much suction)
The booth is pulling too hard, more suction than it should have.
Severity: medium
Exhaust fan not running or running slow
The big exhaust fan that pulls air out of the booth isn't working right.
Severity: high
Booth has low airflow / weak feeling inside booth
The amount of air moving through the booth has dropped. Usually a filter or motor issue.

Show your answers
Is the problem a visible defect in the paint finish — dust nibs, orange peel, fisheyes, runs, or other surface defects?
→ No
Does the booth refuse to start, or shut itself down on its own during operation?
→ No
Is overspray clearly escaping the booth into the surrounding shop area?
→ No
Is the booth's pressure reading abnormal — manometer reading too high or too low, or staff notice the booth is pushing/pulling differently than normal?
→ Yes
Is the HMI or booth controls displaying a specific fault code or alarm (VFD fault, gas pressure, flame failure, intake motor feedback, filter pressure)?
→ No
Does the problem track with the WEATHER or season — worse on humid days, hot afternoons, or cold/dry winter mornings?
→ No
Is it specifically the FILTERS — loading too fast or slow, uneven, or a filter-bank pressure alarm (rather than weak airflow or a dead fan)?
→ No
