INLINE BALANCE PRESSURE FOAM PROPORTIONER
A precision foam proportioning system designed for use with a positive displacement foam concentrate supply pump and atmospheric foam concentrate storage tank. The Inline Balance Pressure Foam Proportioner accurately controls the injection of foam concentrate into the water stream across a wide range of flow rates and pressures, ensuring consistently proportioned foam solution regardless of system demand.
Ideal for installations requiring simultaneous operation at multiple foam injection points — even where pressures differ between injection locations — with a single concentrate supply line. Multiple sizes can be combined to suit the specific flow requirements of each hazard area.
