W-50SS Sanitize / Rinse / A-40SS Airless Foam Hose Drop Station

Model # 912925

The W-50SS Sanitize / Rinse / A-40SS Airless Foam Hose Drop Station is a combination system for applying one chemical as foam, another as a sanitizing spray and for rinsing all without compressed air. This venturi injection system uses boosted water pressure (125 - 350 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 10 feet. Apply sanitizer solution, or any other chemical, as a "flooding spray" using the adjustable pattern spray trigger gun.

Key Features
  • No compressed air required
  • Designed for foaming & sanitizing medium to large surfaces and equipment
  • 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)
  • Dilutes concentrated sanitizers to the lean ratios required for no-rinse applications in food plants
  • Sanitizer is projected as a "flooding spray" for full coverage
  • Sanitize and rinse using the trigger gun with an adjustable cone/stream spray pattern
  • All stainless steel components ensure durability and years of trouble-free performance
  • Available without a rinse function (#912920)
  • See other boosted water pressure units in Catalog 2
