20″ Big Blue with water pressure release

20″ Big Blue Water Filter Housings are ideal substitutes for costly low pressure stainless steel vessels. Big Blue 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 with ¾” in and out allows for greater cartridge capacity, reducing the number of vessels required for high-flow rate applications. Big Blue Housings are compatible with a broad range of chemicals. Reinforced polypropylene housings have excellent chemical resistance and are ideal for many residential, commercial and industrial applications.
