Rainwater harvesting filter for bigger roof areas up to 1200m sq. The Twin Filter can be installed either above ground or in an underground chamber or directly on the tank. Normally standard concrete chambers are used for underground installations. Can can also be installed in any plastic or GRP chamber of a suitable size.
Two step cleaning system offers high level of filtering efficiency, independent of flow rate.

The filtered clean water is collected and sent to the clean outlet for storage in a rain water tank.
