Thanks to its physically rigid construction and precision-engineered, injection-molded slots, the 0.2 mm slots allow for uniform distribution of air and water, while preventing sand and media smaller than 400 microns (0.4 mm) from passing through or obstructing the underdrain slots.
I.M.S 200 media retainer is engineered to allow for more available media expansion for improved backwashing and air and water distribution, eliminating deadspaces, and providing longer filter runs for cleaner media. The patent pending baffles on the bottom of the plate are designed to ensure air doesn’t roll to the high end of the cap.
Suitable for drinking water plants and desalination plants;
Provides even backwash distribution to deep clean filter media;
More driving head results in longer filter runs;
Reduces construction costs reducing vertical footprint by 28-35 cm by eliminating gravel support allowing for the same media depth in less vertical space;
Physically rigid design reduces flexing and withstands pressures up to 15 psi;
Precision-engineered 0.2 mm slots support media down to 450 microns;
