For aboveground pools, the Sta-Rite System:2 Mod Media system is the ideal ultra-capacity filter. It can handle dirt loads up to 15 times greater than sand filters of equivalent size. Its balanced flow tank hydraulics direct water through each side of the filter module for uniform dirt loading which in turn prevents clogging resulting in more dirt to be captured between cleanings to minimize maintenance time. Quality construction with durable, two-piece tank housing. Thermoplastic to ensure a long-lasting tank life. Innovative balanced flow design for virtually maintenance-free operation for pools of all sizes. Complete media coverage combined with shallow pleats means greater dirt holding capabilities, resulting in longer filter cycles and less cleaningPerfect for aboveground pools, inground pools, and inground hot tubs. No backwash valve required. Operating limits - Maximum continuous operating pressure of 50 psi. Pool/spa (bather) applications, maximum operating water temperature (internal filter) 104 degrees F (40 degrees C). This variant has an Effective filter area of 100 square feet with a 38-100 Flow Rate (GPM). Operating Limits - maximum continuous operating pressure of 50 psi. Pool/spa (bather) applications, maximum operating water temperature (internal filter) 104 degrees Fahrenheit (40 degrees Celsius).
