Products Pleated Filter Cartridges Pleated Depth Cartridges

Duo-MAXX / Duo-Pleat Dual-Pleat Cartridge

Designed as a "pre-final" filter, Strainrite's depth over membrane cartridges were created to protect final filters saving money and extending the life of your final filters. These filters incorporate a synchronized media design. This design utilizes a prefiltration layer up-stream over a final membrane layer in the same cartridge. These filters are a pre-filter and a final filter in one.
