• This air intake filter is designed to provide optimum performance over a wide range of design conditions. The unique PBT-32™ Tackifier holds dirt in place; will not dry out, drip or blow off. The self-sealing gasket and internal wire frame eliminate by-pass and flutter to keep dirt out of the spray booth. Substantially outlasts other filters and spreads installation and replacement costs over a longer lifetime. Fits frames fast without adaptors or sharp edges for reduced labor costs.
