Coating Applications
Spray booth filtration for coating operations.
Organize supply-air and exhaust filtration around the booth layout, coating process, airflow path, and maintenance routine.
Spray booth filtration is a system discussion. Incoming air, the booth ceiling or supply section, and the exhaust path each have a different job and should be reviewed together.
Where filtration sits in a coating system
Air intake pre-filter media can be used at the incoming-air side to catch larger airborne contamination before air enters the booth system. In many booth layouts, ceiling filter media is installed in the supply section to condition air entering the spray area. On the exhaust side, paint arrestor filter media is selected to collect paint overspray before the air reaches fans, ductwork, or a downstream treatment stage.
Filter placement and format depend on the equipment design. A replacement program may use rolls, pads, cut sheets, or media prepared for an existing holding frame. Confirm the actual installation point before comparing a current sample with another product.
Selection Checklist
Information that helps avoid a poor filter match.
- Airflow path: identify whether the media sits at the inlet, ceiling, exhaust, or another stage.
- Installation format: provide the opening size, support grid, holding frame, and required roll or cut-piece format.
- Coating conditions: explain the coating material, application method, production rhythm, and observed overspray loading.
- Maintenance plan: describe current replacement practice and any available pressure or visual inspection routine.
For a closer look at exhaust media selection, see the paint arrestor filter media guide. For automotive and furniture finishing, review the automotive and furniture spray booth filtration application page and the intake vs. exhaust filter guide.
