The WPS Single Foam Stick System is a foam applicator designed for car-wash pre-soak, brush lubrication or to apply any foaming product. This system uses a rugged, air-operated, double-diaphragm Warren-Rupp pump to either draw ready-to-use chemical or to draw water and chemical concentrate from static tanks and accurately blend them using precision metering tips. Thick, rich, clinging foam is created by injecting compressed air into the solution to greatly expand volume and coverage ability. The foam is then projected through the pair of 6 foot foam sticks. A fixed flow rate allows just one air valve to easily adjust foam quality for both sticks. Great for retrofitting and for new installations.
