RWH200 Rain Water Filter

RWH filters can be used where rainwater from the roof is channelled 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 drain or soakaway.

Rainwater enters the inlet connection in the side of the RWH unit. The inlet is designed to swirl the water around the surface of he 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 the drain outlet by the action water flowing down the surface of the filter. More than 95% of the rainwater entering the RWH filter is filtered and collected by this principle.

Pitched roofs of slate, clay or concrete are the most suitable for collecting rainwater. Flat roofs can also be utilised but the volume of water collected is reduced. Planted roof areas or thatch are less suitable due to the low collection efficiency and discolouration of the collected water.
