The Green-Clean technology from Forsta Filters utilizes smaller flush valves to minimise the volume of water required to remove build-up on a filter element while maintaining system flow during backwash. An internal vacuum nozzle scans and removes debris from the filter in less than 15 seconds. Forsta Filters’ range of self-cleaning water filters (1-36” flange size), incorporate screen elements ranging from 5 to 4,000 micron.
