Description

The Pentair Triton® C‑3 TR140C‑3 filter is engineered for long life in demanding commercial environments. Its durable Glas‑Lok fiberglass tank resists structural stress from UV, chemicals, and impacts. Internally, the multi‑diffuser configuration delivers uniform distribution across the sand media, reducing channeling and improving cycle length. The use of 3″ flanged connections lowers friction and supports higher flows, making it ideal for large pool systems. Rated to handle ~141 GPM over its 7.06 sq. ft area, it’s built for high performance. Because it ships without a valve, you have the flexibility to install the control style that best matches your plumbing setup.

Pro Tip

Select a 3″ flanged multiport or slide valve to maintain optimal flow. For dual filter systems, consider pairing with a SCH‑40/80 tandem piping kit.
