The Coin Operated 1-Way FPV-PD Concrete Foamer is a timed foam applicator for projecting highly corrosive chemicals such as those used to remove concrete and for aluminum brightening. This acid-resistant system uses a cost-effective Flojet air-operated, double-diaphragm pump to draw ready-to-use acid solution from a static tank and inject compressed air to greatly increase volume and coverage ability. Rich, clinging foam is projected through the hose, wand and fan nozzle on to any surface. This unit features an adjustable timer which controls the length of application, preventing costly over-application. A coin acceptor triggers the timer, which in turn controls the air solenoid for activation of the foamer. The timer can be set to operate the device for up to 17 minutes. The control box also includes a toggle switch and button which can be used to bypass the coin mechanism, if desired. 100 coins are included.
