All Robwen foam products are automatic, discharge-side, mechanical systems powered only by the flow of water.  The BCF configuration is designed to be permanently installed on mobile fire apparatus.  Each system consists of a differential pressure valve, control panel, 2 electric refill pumps and 2 bladder tanks.  The bladder tanks are available in 5 gallon (19L), 7.5 gallon (28L), 10 gallon (38L), 15 gallon (57L) and 20 gallon (76L) capacities.  The ports on each of these 6 components come color-coded to simplify the hose connections during the installation process.

The BCF was primarily designed to be used as a dual agent agent system.  There are no common pathways where two, non-compatible foam concentrates could make contact.  The BCF is also used by agencies desiring a large volume of class A foam.  A Model 1000BCF (two 10 gallon tanks) will treat 4000 gallons of water before any refilling is necessary.
