Big Clear Heavy Duty Series

Pentair Pentek Big Clear Filter Housings offer the versatility to meet all of your large capacity filtration needs, including high-flow and heavy-sediment applications. The extra large housing allows for greater cartridge capacity, reducing the number of vessels required for high flow-rate applications. Sumps are available in both 10″ and 20″ lengths.

Big Clear Filter Housings offer on-site examination of flow, performance, and cartridge life and are ideal for a variety of applications. The 1″ polypropylene caps are available with a pressure-relief button on the inlet side to relieve pressure inside the housing and are available in 10″ and 20″ lengths.

Caps are constructed of reinforced polypropylene. The 10″ sumps are made of Lexan® and the 20″ sumps are SAN (Styrene acrylonitrile).
