Description

The Pentair THS3461 34"×61" Horizontal Sand Filter is engineered for durability and continuous performance. The composite laminate shell eliminates the need for winding, and its 50 PSI rating ensures rugged service in commercial or large residential installations. The front-mounted manway reduces real estate needs while providing full access to internals. Internally, a manifold plus V‑groove lateral system helps balance flow and reduce clog points. With compatibility for a range of backwash controllers, the THS3461 adapts to evolving system demands.

Installation Tips
