Lock Box 2-Way HPSS Foamer

Model # 918117-LB

The Lock Box 2-Way HPSS Foamer is a 2 GPM @ 700 PSI foam applicator for projecting 2 foaming chemicals on to any surface up close or at a distance. This model features a stainless steel, locking enclosure. This stainless steel venturi injection system uses high water pressure (400 - 1000 PSI) to draw and blend chemical concentrates into the water stream to create an accurately diluted solution. Rich, clinging foam is created by injecting compressed air into the solution to greatly increase volume and coverage ability. The foam is then projected through the discharge hose and fan nozzle at distances up to 13 feet. Adjust the ball valves to apply the 2 chemicals separately or together.

Key Features
  • Projects a medium volume of rich, clinging foam which increases chemical contact time and effectiveness
  • Designed to apply 2 separate chemicals or 2 different concentrations of the same chemical
  • Chemicals can be applied separately or simultaneously by adjusting the ball valves
  • Designed for foam cleaning medium to large surfaces
  • Fan pattern nozzle for quick coverage (up to 13' range)
  • Optional zero degree nozzle for increased foam throw
  • Covers up to 500 sq ft (46.5 sq m) in 2 minutes
  • Adjustable foam consistency (wet/dry)
  • Stainless steel enclosure protects equipment from heavy-abuse and prevents unauthorized tampering of dilution and air settings
  • Chemical resistant stainless steel components ensure years of outstanding performance with minimal maintenance
  • Industrial-strength design holds up in tough environments
  • Available without enclosure (#918117)
