Pentair Diffuser Assembly TR140

The Pentair Diffuser Assembly for TR140 (part number 154906) is an internal plumbing component meticulously designed for the Pentair Triton II side-mount fiberglass pool and spa sand filter, specifically tailored for the high-capacity TR140 model. Positioned at the very top of the internal standpipe inside the 36-inch filter tank, this specialized diffuser features a curved, swing-away design that evenly distributes incoming pool water across the top of the 925-pound sand media bed. This uniform dispersal prevents high-velocity water from creating channels through the sand, ensuring optimal filtration performance across the entire surface area. Molded from thick, structural, chemical-resistant PVC to handle heavy continuous hydraulic flow, the component is strong yet light enough to be effortlessly pushed aside during routine media changes or tank inspections. The entire replacement assembly carries a component and shipping weight of approximately 0.68 pounds (about 10.9 ounces), offering a precise, factory-fit solution for maintaining standard flow dynamics within large residential and commercial filtration systems.
