The fiberglass exhaust filter paint arrestor pads are a standard filter media for any spray booth. The progressively dense two-stage 15g media is manufactured from continuous strands of glass fibers engineered to collect and retain a wide range of automotive and industrial-type coatings. The backing is a tightly woven 100% fiberglass construction allowing low initial static pressure. This widely popular overspray media is green/white in color and provides compliant efficiency at an economical price. (Air enters white side and air exits green side).
