Auto Discharge D.E. Filters CEN

Alphafilter CEN filters are designed for ease of use and simplicity. All CEN filters are designed to be highly sanitary and easy to clean. CEN filters are composed of a filtering chamber and complementary components, which work together for operations such as pre-coating, filtration with continuous addition of regulated quantities of diatomaceous earth, cake discharge by automatic rotational centrifugal force from the plate-pack and lastly, final rinsing of the filtering elements. CEN filters have the added benefit of automatically discharging the spent D.E., thus saving time and energy.
