SFTM Top Mount Sand Filter

No More Sand Migration or Channeling


No More Sand Migration or Channeling

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° 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/sq.ft.) for higher flows, better filtration, longer cycles and more efficient backwashing.
