W-20SS Sanitize / A-20SS Airless Foam Hose Drop Station

Model # 917920

The W-20SS Sanitize / A-20SS Airless Foam Hose Drop Station is a combination system for applying one chemical as foam without compressed air and another as a sanitizing spray. This venturi injection system uses high water pressure (400 - 1000 PSI) to draw and blend chemical concentrates into the water streams to create accurately diluted solutions. Precision metering tips are used to control chemical usage. Foaming chemical solution flows through the foam hose and trigger gun to the "airless" foam wand which draws in atmospheric air to create and project wet, clinging foam at distances up to 12 feet. Sanitizer solution, or any other chemical, is projected using the trigger gun and fan nozzle.

Key Features
  • No compressed air required
  • Designed for foaming & sanitizing medium to large areas
  • Projects wet, clinging foam which increases chemical contact time and effectiveness
  • Foaming expands the chemical and reduces over-application by providing visual assurance of coverage
  • Fan pattern foam nozzle for fast coverage at distances up to 10' and zero degree nozzle for up to 12' foam throw (depending on water pressure)
  • Sanitize using a dedicated hose, trigger gun & fan nozzle
  • Stainless steel components ensure years of outstanding performance with minimal maintenance
  • Available with a rinse function (#917927)
  • See other high water pressure units in Catalog 3
