Big Blue® filter housings offer the versatility to meet all of your large capacity water filtration needs, including high-flow and heavy-sediment applications. The extra large filter 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 both 10" and 20" lengths.
The high-flow polypropylene (HFPP) cap is available with 3/4", 1" or 11⁄2" NPT inlet and outlet ports. The 11⁄4" 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 41⁄2" diameter cartridges in either 10" or 20" lengths.
