Product Overview

The Pentair Triton C-3 TR100C-3 (140310) is a 30-inch, high capacity side mount sand filter for commercial pools. It has 4.91 sq ft of filter area and handles up to 98 GPM. Pentair's patented Glas-Lok process forms a one-piece, fiberglass-reinforced tank with a UV-resistant finish that keeps fibers from "blooming" in harsh conditions. A multi-diffuser system raises filtration rates to as much as 20 GPM per sq ft, and the C-3 model has standard 3-inch flange connections. The filter ships without a valve.

⚠️ Important Purchase Notice

The valve is not included; choose a compatible 3-inch flanged valve or manifold separately. Filter sand and pea gravel are also sold separately. Commercial installations must meet state and local health department requirements. This is a freight item; inspect the shipment on arrival and report any damage promptly.
