About this cartridge type
Pleated cartridges give a large surface area in a standard housing, which keeps pressure drop low at higher flow rates. The SPC series pleats polyester media around a polypropylene core, with vinyl plastisol ends fused into a combined end cap and gasket, and is washable and reusable in many uses. Before you switch, compare media type, end cap style and the pressure drop at your flow, and tell us any certification your specification calls for.
