SPTA Series Foreline Traps

SPTA Inlet Filter Traps feature right angle mounting configuration, with female NPT Inlet / Outlet ports for easy mounting. Units are of steel construction, with a baked enamel finish. The filter itself is a heavy duty, pleated, five (5) micron, polyester cartridge. Polyester filters have a high dirty carrying capacity, is washable with warm water and mild detergents, thereby extending service life of the cartridge. Additionally, the cartridge incorporates a foam polyurethane "pre-filter" which allows a much higher dirt carrying capacity (typically 50%). Stainless steel torsion clips hold the bonnet assembly firmly in place and allow quick access for maintenance cycles. All SPTA Series Inlet Filters feature ¼" female NPT ports which are located on the inlet and outlet ports allowing the use of gauges, should the need arise.
