The SFTM Top-Mount Pool Sand Filter directs water evenly across the entire surface of sand without sand migration or channeling. Top-mount pool sand filters contain an extra deep sand bed for improved filtration. Its blow-molded tank is corrosion- and UV-resistant with a bottom drain that's ideal for winterizing and draining. Other features include 7-way dial valve with sight glass, automatic air relief and pressure gauge.
The SFTM has a non-corrosive resin clamp that allows 360 degree rotation of the dial valve for simple installation, alignment, and service of dial valve and filter components. A heavy-duty, freeze-resistant under-drain with snap-fit side slotted laterals draws water evenly across the full diameter of the sand bed (up to 25 GPM per square foot) for higher flows, better filtration, longer cycles, and more efficient backwashing.
