Description

The Pentair THS4272 42"×72" Horizontal Sand Filter is built for durability in high‑demand settings. Its composite laminate construction eliminates the need for external winding and endures thermal and mechanical stresses. With a 50 PSI rating, it tolerates pressure fluctuations typical of large filtration systems. The internal manifold and V‑slot lateral assembly guarantees broad media use and even flow distribution, minimizing clogging or bypass zones. The front manway offers full access while minimizing equipment‑pad footprint. This model is compatible with Pentair’s full suite of backwash control systems — from manual to fully automatic — enabling future upgrades with ease.

Pro Tip

Select a 6" flanged manifold kit to reduce on‑site plumbing work and simplify maintenance.

Installation Tips

Ensure the base is level, rigid, and supports full load. Partially fill the tank before adding sand to prevent lateral damage. Use proper media (0.45–0.55 mm silica). All flanged or threaded connections should be rated above 50 PSI. Provide air‑relief, drainage, and bleed lines. Hand‑tighten the manway cover to recommended torque.
