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

Model # 918104

The W-20SS Sanitize / Rinse / TGSS Foam Hose Drop Station is a combination trigger gun applicator for applying one chemical as foam, 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, trigger gun, and fan nozzle and is projected at distances up to 10 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
  • Trigger guns allow the user to start and stop application with ease
  • Trigger guns shut off automatically if dropped to enhance safety
  • Spray gun produces a medium volume spray for sanitizing and rinsing
  • Foam gun projects rich clinging foam that increases chemical contact time and effectiveness
  • Foaming expands the chemical and reduces over-application by providing visual assurance of coverage
  • Fan nozzles provide quick and even coverage
  • Foamer covers up to 500 sq ft (46.5 sq m) in 4 minutes (up to 10' range)
  • Adjustable foam consistency (wet/dry)
  • Stainless steel components ensure durability and years of trouble-free performance
  • See other high pressure foamers in Catalog 3
