The TransFoamer Plus is an "adjustable flow" foam applicator for feeding 8 - 14 foot long foam bars with chemical solution at up to 5.3 GPM @ 50 PSI. This venturi injection unit uses city water pressure (50 - 125 PSI) to draw and blend chemical concentrate into the water stream and creates a wide range of dilution ratios. Rich, clinging foam is created by injecting compressed air into the solution to greatly expand volume and coverage ability. The water, chemical and air flow can be adjusted "on-the-fly" via needle valves. This versatile unit can be used for both new installations and to retrofit existing foam bars.
