The Sandmaster filter features an integral top diffuser that evenly distributes unfiltered water over the sand media bed in a cascading, umbrella-like pattern. This allows the greatest filtration possible from every square inch of sand. Then the self-cleaning under drain assembly, with its 360° slotted laterals, provides a fast, balanced flow of clear water back to the pool while allowing for more thorough backwashing. Best of all, the Pro's full-flow technology reduces your energy costs because the filter operates for shorter periods.

These high-performance pool filters combine rugged construction, energy-efficient operation and superior flow rates for years of trouble-free filtration with minimal care.

The weather-proof tank is constructed of a tough color-fast polymeric material and topped with a patented easy to use multi-port valve.

All Sandmaster pool filters feature an integral top diffuser, self-cleaning underdrain and 360 degree slotted laterals to ensure even water distribution over every square inch of sand, thorough backwashing and totally balanced flow for crystal clear water.

This advanced full flow technology reduces energy costs by obtaining maximum filtration, so you can run your filter less.

  • 3' of hose included
  • Sand Required - 56 KG / 125 Pounds, not included
