MASTEP Evaluation Summary
This product was evaluated in at least one third-party study. See MASTEP Evaluation Summary.
In Brief:
The filter consists of a spring-loaded spine that holds a number of stacked, diagonally-grooved polyproplylene discs enclosed in a corrosion and pressure-resistant housing. The stacked discs create a filtration element with a statistically significant series of valleys and traps. During filtration, the discs are compressed by the spring and the differential pressure of the water, which flows from the peripheral end to the core of the element. Backwashing involves release of the compression spring and high-pressure flow of clean water through nozzles at the center of the spine. The discs spin free and solids are efficiently flushed out through the drain. Modular batteries allow for easy expansion of system in various space-saving configurations.
