Pump Fed TransFoamer

Model # 919290

The TransFoamer is an "adjustable flow" foam applicator for feeding 4 - 8 foot long foam bars with chemical solution at up to 7 GPM. This unit receives ready-to-use chemical solution from a central chemical feed system and creates rich, clinging foam by injecting compressed air to greatly increase 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 that are properly sized.
