The intake filters (prefilters) are the primary defense against foreign particles landing on the painting surface. Any particle larger than 10 microns can cause a defect on a paint job. Intake filters are typically either panels or pads. Intake filters in a down draft booth and prep stations are above the painting surface. In cross draft booths, they are typically in the door.
Exhaust booth filters (postfilters) play an important role in maintaining proper air flow balance, increasing cleanliness of exhaust stacks, reducing maintenance of the exhaust system and in controlling V.O.C. emissions. The purpose of exhaust filters is to capture overspray particles and remove them from the air stream as air is removed or re-circulated back into the booth.What is difference between prefilter and postfilter in powder coating booth?
