Hydra - Self Cleaning Filter System

HYDRA is a full range of self-cleaning filters with innovative solutions for the efficiency of self-cleaning operation, thanks to a newly designed back-wash system in counter-current which grants the highest particle removal from the filter cartridge. The cleaning operation with back-wash is simply operated by the opening of the discharge valve at the filter bottom, the resulting pressure-drop pushes the specially designed cartridge downward the housing bottom and reverses the water flow from the outer to the inner side of the cartridge, washing away the sediments trapped onto the outer surface of the cartridge. Sediments are then discharged from the bottom valve, which is provided with a drain funnel designed to prevent contamination by back-flow in compliance with the European Standard UNI EN 1717/2002.
