The Shiner Auto 1.5 Litre Foamer Pressure Sprayer is Perfect for Snow Foaming without the need of a pressure washer. It features a clearly graduated, chemically resistant, high-density polyethylene (HDPE) tank, a foaming spray nozzle and a safety valve. It also features ethylene propylene diene monomer rubber (EPDM) seals and a polypropylene (PP) pump, which makes it base resistant and thus ideal for use with alkaline (pH 7-14) snow foams.
