Timed Asphalt Release Uni-Body Foamer

Model # 977034

The Timed Asphalt Release Uni-Body Foamer is a foam applicator for applying asphalt release chemicals on to truck beds or tools to prevent asphalt from sticking. This unit features a dual-function adjustable 120V timer which controls the length of application and the delay time, which keeps the driver from immediately restarting the system, preventing costly over-application. When activated, this venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend chemical concentrate into the water stream to create an accurately an accurately diluted solution. Compressed air is injected into the solution to greatly increase volume and coverage ability. Rich, clinging foam is then projected through the discharge hose, wand and fan nozzle.
