Description
The Pentair THS4284 42"×84" Horizontal Sand Filter provides durable, high-throughput filtration tailored to large-scale aquatic systems. Its composite laminate construction eliminates reliance on winding and resists delamination or fatigue. With a 50 PSI rating, it accommodates internal pressure surges safely. The internal manifold and V‑groove lateral design ensures uniform flow and reduces clogging. The front manway configuration enables full access with minimal spatial demand. Compatible with a range of backwash controllers, THS4284 is designed for both present operation and future growth.
Pro Tip
Use the correct 6″ flanged manifold kit to simplify plumbing, reduce field adjustments, and lower long‑term labor costs.
Installation Tips
Ensure the base is level and structurally rigid. Pre-fill with water before media addition. Use proper sand (0.45–0.55 mm). All connections and flanges must exceed 50 PSI rating. Provide air-relief and drainage lines. Adhere to manway bolt torque specs to prevent shell distortion.
