Paint Booth Exhaust Filters
Exhaust filters are the last stage of a paint booth’s air filtration system. They can be pads or rolls of media such as fiberglass or polyester or can be made of cardboard depending on the application. Paint Booth exhaust filters can be used along the floors, along the side walls, and in exhaust towers at the end of the paint booth depending on how the booth is designed by the manufacturer. Exhaust filters help paint booths meet regulations by catching all of the extra paint and remaining solvents before the air inside is released back into the environment. Because exhaust filters serve this essential purpose, they typically come built into every standard spray booth.
Polyester exhaust media is typically much more efficient than fiberglass filters and will keep your equipment mechanicals cleaner and reduce breakdowns.
When to Change Your Exhaust Filter
Spray booth exhaust filters require much more frequent changes than their ceiling/intake filter and pre-filter counterparts. Depending on the number of paint jobs and the filter type, exhaust filters should regularly be changed weekly, bi-weekly, or monthly.
