Abstract
A system supplies compressed air and foam to produce a fire stream comprising an aerated foam. The system includes a fire pump, an air compressor, a mixer, and a controller for automatically maintaining a desired ratio of air and water delivered from the mixer to a fire stream delivery device. An electronic control unit is arranged to sense both the flow rate of the water delivered by the fire pump and the air flow rate delivered by the air compressor, and modulates an air pressure signal used to vary the flow of air to the inlet of the air compressor so as to hold the air flow rate and the water flow rate at the desired ratio.
