Air Foam Proportioners
Discription
Air Foam Proportioners / Inline Inductors are venturi devices that introduce Foam concentrate into a flowing stream of water at a controlled rate.
The rate of solution flow from the device is related to the inlet pressure of proportioner. In addition to water pressure, handline proportioners are sensitive to back pressure. Back pressure is the amount of pressure required downstream of the proportioner to discharge the total foam solution flow. The total allowable back pressure on the discharge side of the handling proportioner/inline inductors should not exceed 65% of the water inlet pressure.
When using handline proportioners / inline inductors as portable devices, a pick-up tube is provided to draw foam concentrate from the portable foam containers.
