Pentair 36" Triton® C-3 High Capacity Fiberglass Side Mount Sand Filter TR140C-3 Black

Pentair Triton® C-3 High Capacity Side Mount Sand Filter TR140C-3 (Black)

The Pentair Triton® C-3 TR140C-3 is a commercial-grade, maximum-capacity 36-inch side-mount sand filtration system meticulously engineered to deliver exceptional water clarity for large-scale commercial facilities, heavy-use public water parks, and premium high-volume residential inground pools. Molded exclusively in a sleek, industrial black finish, this heavy-duty tank is constructed using Pentair’s proprietary Glaslok™ process, which creates a seamless, one-piece fiberglass-reinforced unibody shell featuring a specialized UV-resistant coating designed to prevent fiber "blooming," structural cracking, and chemical degradation under constant outdoor weathering. Unlike standard models, the C-3 designation incorporates industrial-grade, oversized 3-inch flanged side bulkhead connections that significantly reduce hydraulic friction loss and accommodate high-volume commercial plumbing networks. Internally, an advanced flow distribution system with multiple diverters and a heavy-duty lateral grid forces water evenly across its expansive 7.06 square feet of effective filtration area, comfortably supporting an impressive design flow rate of up to 141 gallons per minute (GPM) at a maximum operating threshold of 50 PSI. This balanced internal flow profile maintains a perfectly flat sand bed to optimize particle-trapping efficiency while drastically extending the duration between required backwashing cycles, preserving thousands of gallons of balanced water and chemical treatments each season. The tank features an extra-large 8-inch threaded opening with an integrated pressure gauge and manual air relief valve for tool-free sand bed inspection, alongside a full 2-inch bottom drain port designed for rapid winterization and media cleanouts. Shipped open without an attached valve body, it gives facility operators full flexibility to install tailored high-flow multi-port backwash manifolds or slide valves. The dry product weight of the Pentair Triton C-3 TR140C-3 filter tank body is approximately 82 pounds (noting that a full operational deployment requires an additional 925 pounds of media, traditionally split into 650 pounds of pool silica sand and 275 pounds of pea gravel), establishing it as an incredibly rugged, low-maintenance, and hydraulically superior powerhouse for large-scale aquatic environments.
