Big Blue® filter housings offer the versatility to meet all 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 constructed of durable reinforced polypropylene and are available in 10” and 20” lengths.

The high flow polypropylene (HFPP) cap is available with 3/4”, 1” or 1-1/2” NPT inlet and outlet ports. The 1-1/4” internal port allows a greater volume of liquid to pass through the HFPP cap more rapidly.

Big Blue® housings are compatible with a broad range of chemicals and are available with or without an optional pressure relief button. They accept a wide variety of 4-1/2” diameter cartridges in either 10” or 20” lengths.
