Pentair Triton® II Side Mount Sand Filter TR140 (Almond)

The Pentair Triton® II TR140 is a maximum-capacity, heavy-duty 36-inch side-mount sand filtration system meticulously engineered to deliver exceptional water clarity for massive residential pools, large commercial facilities, and demanding high-volume aquatic systems. Featuring a classic almond finish, this commercial-grade tank is constructed utilizing Pentair’s proprietary Glaslok™ process, which fabricates a seamless, one-piece fiberglass-reinforced tank with an advanced UV-resistant shell that completely eliminates structural degradation, cracking, and internal fiber "blooming" over decades of intense outdoor exposure. The side-mount configuration is engineered with threaded bulkhead ports and lacks an attached integrated valve body, allowing pool builders maximum versatility to integrate specialized 2-inch multi-port high-flow valves or slide valve plumbing arrays. Internally, the TR140 is equipped with a heavy-duty 360-degree lateral grid and a swing-away water diffuser that ensures uniform water distribution across its expansive 7.06 square feet of effective filtration area, optimizing dirt-trapping efficiency and comfortably supporting a robust design flow rate of up to 106 gallons per minute (GPM). This uniform flow profile keeps the deep sand bed perfectly level, drastically extending filtration cycles and cutting down on backwash frequency to preserve thousands of gallons of balanced pool water each season. The unit features a large 8-inch threaded top opening with an integrated manual air relief valve for tool-free, rapid media inspection, paired with a combination sand-and-water bottom drain that simplifies winterization and seasonal servicing. The dry weight of the Pentair Triton II TR140 filter tank body is approximately 75 pounds (noting that full operational deployment requires an additional 925 pounds of specialized filter media, or a baseline mixture of 650 pounds of silica sand and 275 pounds of pea gravel), establishing it as an incredibly rugged, high-output, and long-lasting centerpiece for premium pool filtration networks.
