SFTM Top Mount Sand Filter
The SFTM’s deep, high-capacity sand bed carries more debris and extends filter cycles.
Blow-molded tank is corrosion and UV resistant. Bottom drain ideal for winterizing and draining. Other features include 7-way dial valve with "sight glass," automatic air relief, and pressure gauge. Available in two sizes: 22” and 25”. Deep high-capacity sand bed carries more debris and extends filter cycles.
Upper Distribution System 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.
