Description

The SFTM’s deep, high-capacity sand bed carries more debris and extends filter cycles.

The SFTM sand filter is engineered to direct water evenly across the entire surface of the sand without sand migration or channeling. Top-mount sand filters boast an extra deep sand bed for improved filtration. Its blow-molded tank is corrosion and UV resistant and the bottom drain is ideal for winterizing and draining. Other features include 7-way dial valve with “sight glass,” automatic air relief and pressure gauge. Deep high-capacity sand bed carries more debris and extends filter cycles.

Upper Distribution System is integrated into the dial valve and engineered to direct water evenly across the entire surface of the sand. Up to 25 gpm/sq.ft (61 m³/h per m²) without sand migration or channeling.

Non-Corrosive Resin Clamp allows 360° rotation of the dial valve for simple installation, alignment, and service of dial valve and filter components.

Heavy-duty, freeze-resistant under-drain, with “snap-fit” side slotted laterals, draws water evenly across the full diameter of the sand bed for higher flows, better filtration, longer cycles and more efficient backwashing.
