VORTEX FINE FILTER WFF

Description

WFF filters can be used where rainwater from the roof is channeled through a horizontal underground pipe. The unit filters and diverts rainwater to a storage tank or cistern. Leaves, moss and other debris are washed through to drain or soak away. Rainwater enters the inlet connection in the side of the WFF unit. The inlet is designed to swirl the water in a vortex-like action around the surface of the stainless steel filter below. The rainwater is drawn through the vertical mesh walls of the fine filter by adhesion, then collected and fed through the outlet to the storage tank. Debris and particles too large for the filter are flushed through to the drain outlet by the action of water flowing down the surface of the filter. More than 95% of the rainwater entering the WFF is filtered and collected by this principle.
