No More Sand Migration or Channeling

The SFTM Top-Mount Sand Filter directs water evenly across the entire surface of sand without sand migration or channeling. Top-mount 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.

Features

  • High-capacity sand bed carries more debris and extends filter cycles
  • Engineered to direct water evenly across the entire surface of the sand without sand migration or channeling
  • Dial Valve with automatic air relief and pressure gauge
  • Bottom drain for easy winterizing and draining

Technical Details
