Pentair Big Grey

AXEON by Pentair® Big Grey Cartridge 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 constructed of durable reinforced polypropylene and are available in both 10” and 20” lengths. The high-flow polypropylene (HFPP) cap is available with ¾”, 1” or 1½” internal port which allows a greater volume of liquid to pass through the HFPP cap more rapidly. AXEON Big Grey Cartridge Housings are compatible with a broad range of chemicals. They accept a wide variety of 4.5” diameter cartridges.
