Drainfix Clean Filter Substrate Channel System

drainfix clean

Filter substrate channel system that can be used in all applications but especially in densely built areas.

The Drainfix Clean system is an intelligent solution for the draining, collection and treatment at source of storm water runoffs. The system comprises of heavy duty Faserfix Super channels complete with ductile iron grates; load classes D400 to F900.

Each channel contains a carbon rich substrate filter through which the cleansing of the storm water runoff occurs; pollutants such as zinc, copper, lead and fuel hydrocarbons as well as fine particles are trapped within the substrate material. The channels also offer large retention capacities that allow the system to handle high volumes of water.
