Fixed type proportioners work with the reverse pressure logic. The working principle ensures that the foam pumped by the bladder tank or pump comes to the adjustment module and the foam flows into the installation from the determined orifice diameter.

The fixed type proportioner ensures that the foam concentration is accurately proportioned to the water flow across a wide range of water flow rates. Proportioner rates the foam at concentrations of 1%, 3% and 6%. This is an integral part of the proportioner foam systems. The most common used discharge devices are: Sprinklers, Nozzles, Monitors, Foam Makers and Foam generating chambers.
