Uni-Body W-50 Spray / Rinse / Foam Hose Drop Station

Model # 975425

The Uni-Body W-50 Spray/Rinse/Foam Hose Drop Station is a medium volume 3 function system. This venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend 2 different chemical concentrates into the water stream to create accurately diluted solutions. Rich, clinging foam is created by injecting compressed air into the foaming solution to greatly increase volume and coverage ability. The foam is then projected through a dedicated discharge hose and fan nozzle at distances up to 9 feet. The spray application and rinsing is achieved with a second hose, wand and fan nozzle.

Key Features
  • The uni-body design is both compact and cost-effective
  • Designed to foam, rinse and spray a second chemical on small to medium surfaces and objects
  • Projects a low volume of rich, clinging foam which increases chemical contact time and effectiveness
  • Foaming expands the chemical and provides visual assurance of coverage
  • Fan pattern foam nozzle for fast coverage (up to 9' range)
  • Covers up to 500 sq ft (46.5 sq m) in 4.5 minutes
  • Adjustable foam consistency (wet/dry)
  • Apply the second chemical, and rinse, as a fan pattern spray
  • Stainless steel and polypropylene components
  • Available as a portable unit (#975426)
  • See other city water pressure foamers in Catalog 1
