Found out my paint booth filter change was overdue by 40%
We track booth airflow with a cheap manometer I hung near the intake. Last Tuesday I actually charted the numbers for a month and realized static pressure had crept up 40% past the spec in the manual. Swapped the filters and the flash time on clear dropped by 6 minutes per car. I never bothered to log readings before, just went by smell and looks. Anyone else run regular pressure logs or do you just go by schedule?
