A New Class of Noncartridge Filtration

No longer using "cartridges," Sta-Rite's advanced technology has brought an entirely new class of filtration to your pool. The modular media concept incorporates the latest in media science, perfectly balanced flow, and an integral manifold design: namely, ultra-capacity filtration. This filtration concept puts totally care-free operation within reach. Modular filter tanks allow for quick change of filter medias without changing the tank. Contemporary style and matte black finish look attractive in any pool setting.

  • Typical installation—inground pools, inground hot tubs and water features
  • Durable, two-piece tank housing constructed of Dura-Glas™, the leading glass-reinforced composite resin
  • The innovative balanced flow design is the standard of the industry
  • Complete media coverage combined with shallow pleats means greater dirt-holding capabilities for longer filter cycles and less cleaning
  • Simply hose off the elements in a matter of minutes—makes servicing a snap
  • Dual drain plugs—side plug available for plumbing to waste, and bottom plug drains entire filter

Note: No backwash valve required.

Note: Operating limits—Maximum continual operating pressure of 50 psi. Pool/spa (bather) applications, maximum operating water temperature (internal filter) 104° F (40 °C).
