Filters are often overlooked when evaluating the performance of a spray booth. A filter is a relatively inexpensive component of a spray booth and should be changed when necessary. Changing filters will help in avoiding poor finish jobs and unsafe conditions caused by inhibited air flow which can build toxic and combustible fumes.
Intake – Change filters when they fill with dust and dirt. Many auto body shops will change filters every two to four weeks if the booth is used daily.
Exhaust – Paint arrestor filters need to be changed under the following conditions:
- When the material being sprayed may react with something that has already been sprayed with these filters so as to create a toxic or spontaneous event.
- The static pressure differential is 0.5” or greater. This differential is measured on the manometer and is based on an empty booth with clean filters. Once the static pressure is above the basis line (0.5”), the exhaust filters need to be changed.
- Powder coat filters can be vacuumed many times and usually last 500-1000 hours.
