  1. Flange Clamp Design allows 360° rotation of valve to simplify plumbing.
  2. Integral Top Diffuser ensures even distribution of water over the top of the sand media bed. Full-size internal piping gives a smooth, free-flowing performance.
  3. Unitized, Corrosion-Proof Filter Tank molded of tough, durable colorfast reinforced thermoplastic for dependable, all-weather performance with only minimal care.
  4. Efficient, Multi-Lateral Underdrain Assembly with precision engineered, self-cleaning 360° slotted laterals gives totally balanced flow.
  5. Integral Molded Drain Plug for easy draining of tank, without the loss of sand.
  6. Totally Corrosion-Proof Base is rugged and attractively styled to provide strong, stable support.

The water enters the filter through the intake bulkhead fitting. It passes through the Integral Top Diffuser which allows the water to disburse evenly over the sand bed inside the tank. As the water passes down through the sand bed, particulate and debris in the water is trapped between the grains of sand. The filtered water is then returned to the pool through the return bulkhead. The air discharges built into the filter tank removes air pockets from the top of the filter tank. The manual air relief valve offers a way to manually remove an air pocket in the filter.

Most sand filters will remove particulate and debris down to a size of about 40 microns.
