Squeaky clean and crystal clear! That'll give you a clear idea of what it's like to have System:3® Sand Filters at work in your swimming pool. This filter is designed to remove more dirt impurities, which will make your water look fresher and more inviting. Sta-Rite has made maintenance easier, too. Cleaning is as simple as applying a little wrist action to the control valve and walking away. And its dirt handling capacity pays off in less maintenance.

System:3 Sand Filters brings you the proven performance of Sta-Rite’s sophisticated sand filter hydraulics in the world’s safest and easiest-to-operate filter. Highly efficient, its sophisticated design yields a uniform flow pattern through a deeper sand bed than any other. (Modular filter tanks allow for quick change of filter medias without changing the tank.) Contemporary style and matte black finish looks attractive in any pool setting. 

Features and Specifications:

  • Quality Construction – Durable two-piece tank housing constructed of Dura-Glas®, Sta-Rite's industry leading glass-reinforced composite resin.
  • Innovative Design – The innovative design of the System:3 tank combined with the lateral/hub assembly produces a balanced flow of water and deeper sand bed penetration.
  • Low Maintenance – The deep sand bed holds more dirt, resulting in longer filter cycles and less cleaning.
  • Dual Drain Plugs – Side plug helps make sand removal easy, while the bottom plug comes with integral screen for easy draining without the loss of sand.
  • Dual Drain Plugs – Side plug assembly includes 1-1/2 inch NPT port for direct discharge plumbing.
  • Sleek Looks – Contemporary style and matte black finish looks attractive in any pool setting.
