W-20SS Sanitize / Rinse / Hyper SS Foam Hose Drop Station

Model # 917227

The W-20SS Sanitize / Rinse / Hyper SS Foam Hose Drop Station is a combination applicator for quickly applying one chemical as foam at 3.3 GPM @ 700 PSI, another as a sanitizing spray and for rinsing. This stainless steel 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 using precision metering tips to control chemical usage. Rich, clinging foam is created by injecting compressed air into the foaming solution to greatly increase volume and coverage ability. The foaming solution then flows through the foam hose and is projected through the fan nozzle at distances up to 13 feet. Rinse and sanitize using the second hose, trigger gun and fan nozzle.

Key Features
  • Designed to foam, rinse and sanitize medium to large sized surfaces and objects
  • Projects a substantial volume of rich, 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 (up to 13' range)
  • Covers up to 500 sq ft (46.5 sq m) in 1.5 minutes
  • Optional zero degree nozzle for increased range
  • Adjustable foam consistency (wet/dry)
  • Stainless steel components ensure durability and years of trouble-free performance
  • Available without a rinse function (#917120)
  • Available with a lower flow rate (#918227)
  • See other high water pressure foamers in Catalog 3
