Summary

Pentek Big Blue® & Big Clear Filter Housings

Pentek Big Blue® and Big Clear filter housings are designed for large-capacity filtration needs, including high-flow and heavy-sediment applications. The extra-large housing design allows for greater cartridge capacity, potentially reducing the number of vessels required for high flow-rate applications.

Big Blue® housings are opaque, constructed of durable reinforced polypropylene sumps. Big Clear housings feature clear sumps (Lexan for #10, Polycarbonate for #20) allowing for on-site examination of flow, performance, and cartridge life.

Both series are available in 10" and 20" lengths and accept 4½" diameter cartridges.

Product identification

• Cap options: High-flow polypropylene (HFPP) cap available with 3/4", 1", or 1½" NPT inlet and outlet ports. Features a 1¼" internal port for greater liquid volume passage.
• Pressure relief: Pressure relief/bleed button on the inlet side of the cap (optional on Big Clear).
