FIXED AND PORTABLE INLINE INDUCTORS
Air Foam Proportioner/In-line 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 proportioner/in-line inductors are sensitive to back pressure. Back pressure is the amount of pressure required down stream of the proportioner to discharge the total foam solution flow.
The total allowable back pressure on the discharge side of the handline proportioner/in-line inductors should not exceed 65% of the water inlet pressure. When using handline proportioner/ in-line inductors as portable devices a pick-up tube is provided to draw foam concentrate from the portable foam containers.
- UL Listed
- Inductor models have metering check valve to adjust foam induction/proportion rate at 3% & 6%.
- For fixed installation having fixed orifice of foam induction/proportion rate at 6%.
- Suitable for use with all foam concentrates.
- Designed to minimum pressure loss across the inductor
- Simple to operate
- Minimal maintenance
- Corrosion resistant
