WPS-MM Asphalt Release Sprayer

Model # 931108WPS

The WPS-MM Asphalt Release Sprayer is a chemical spray applicator for diluting and projecting asphalt release chemicals on to truck beds or tools to prevent asphalt from sticking. This system features a lockable, stainless steel enclosure and uses a 3/8" Warren Rupp air-operated, double-diaphragm pump to draw chemical concentrate and water from separate static tanks and blend them to create virtually any dilution ratio. The solution is then projected through the discharge hose, trigger gun, wand and fan nozzle.
