Rinse / A-40SS Airless Foam Hose Drop Station

Model # 912918

The Rinse / A-40SS Airless Foam Hose Drop Station is a combination medium volume foam applicator for projecting foaming chemicals on to any surface up close or at a distance and for rinsing, without compressed air. This stainless steel venturi injection system uses boosted water pressure (125 - 350 PSI) to draw and blend chemical concentrate into the water stream to create an accurately diluted solution. The solution then flows through the discharge 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 10'. Rinse at full pressure through a separate hose and adjustable pattern trigger gun.

Key Features
  • No compressed air required
  • Designed for foaming & rinsing medium to large surfaces
  • 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
  • Projects foam up to 10' (depending on water pressure)
  • Rinse using the trigger gun with an adjustable cone/stream spray pattern
  • All stainless steel components ensure durability and years of trouble-free performance
  • Industrial-strength design holds up in tough environments
  • Available without a rinse function (#912905)
