2-Way A-20SS Airless Foamer

Model # 917907

The 2-Way A-20SS Airless Foamer is a 3.1 GPM @ 700 PSI foam applicator for projecting up to 2 foaming chemicals on to any surface up close or at a distance without compressed air. This stainless steel venturi injection system uses high water pressure (400 - 1000 PSI) to draw and blend chemical concentrates into the water stream to create accurately diluted solutions. The solutions then flow 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. Use the ball valves to inject the 2 chemicals separately or simultaneously.

Key Features
  • No compressed air required
  • Designed for foam cleaning medium to large sized areas
  • Projects wet, clinging foam which increases chemical contact time and effectiveness
  • Designed to apply 2 separate chemicals or 2 different concentrations of the same chemical
  • Chemicals can be applied separately or simultaneously by adjusting the ball valves
  • Foaming expands the chemical and reduces over-application by providing visual assurance of coverage
  • Fan nozzle for fast coverage at distances up to 10' and zero degree nozzle for up to 12' foam throw (depending on water pressure)
  • Stainless steel components ensure years of outstanding performance with minimal maintenance
  • Available for one chemical (#917905)
  • See other configurations of Lafferty high water pressure foamers in Catalog 3
