Pentair Big Blue and Big Black heavy-duty 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 in and 20 in lengths. The HFPP cap is available with 3/4 in, 1 in or 1-1/2 in NPT inlet and outlet ports. The 1-1/2 in internal port allows a greater volume of liquid to pass through the HFPP cap more rapidly. Big Blue and Big Black housings are compatible with a broad range of chemicals and are available with or without a pressure relief button. They accept a wide variety of 4-1/2 in Dia cartridges.
