Rainwater filter for large roof areas. The Twin Filter can be installed in chambers underground or directly on the wall kept frost free. Usually installed in standard 1000mm manholes. The filter could also be pre-installed in chambers prior to delivery to site.
Due to its two step cleaning system, it has a high level of filtering efficiency, independent of flow rate. Due to the steep inclination of the filter cartridge the dirt is continuously cleaned away into the sewer. The cleaned water is collected in a tank and directed into the storage. The 3p two step filtration system is a tried and tested proven technology.
Connection capacity for roof areas up to 800m². A bypass-installation can be used to connect to a bigger area.
