Rinse / A-20SS Airless Foam Hose Drop Station

Model # 917918

The Rinse / A-20SS Airless Foam Hose Drop Station is a combination applicator foam/rinse for projecting foaming chemicals at 3.11 GPM @ 700 PSI, without compressed air, and for rinsing. This stainless steel venturi injection system uses high water pressure (400 - 1000 PSI) to draw and blend chemical concentrate into the water stream to create an accurately diluted solution. The solution then 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 on to any surface up close or at distances up to 12'. Rinse at full pressure through a separate hose, trigger gun and fan nozzle.

Key Features
  • No compressed air required
  • Designed for foaming & rinsing medium sized surfaces where compressed air is not available
  • 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 nozzle for fast foam coverage at distances up to 10' and zero degree nozzle for up to 12' foam throw (depending on water pressure)
  • All stainless steel components ensure durability and years of trouble-free performance
  • Available without the rinse function (#917905)
  • See other configurations of Lafferty high water pressure foamers in Catalog 3
