3-Bar Truck Foam Arch

Model # 910930

The 3-Bar Truck Foam Arch is a drive-through foam applicator for washing large vehicles and features 3 foam bar assemblies mounted above and and at the sides of the vehicle for complete coverage. This venturi injection unit uses city water pressure (40 - 125 PSI) to draw and blend chemical concentrate into the water stream to create accurately diluted solutions using precision metering tips. Compressed air is injected to greatly increase volume and coverage ability, creating rich, clinging foam that is projected through multiple fan nozzles on each foam bar. The foam consistency (wet/dry) can be adjusted.

Key Features
  • Dilutes chemical concentrate at the unit independently for each foam bar
  • Creates rich, clinging foam which increases chemical contact time and effectiveness
  • Foam consistency (wet/dry) is adjusted with a single air regulator
  • Chemical resistant wetted components ensure durability and years of reliable performance
  • Water and air pressure gauges eliminate guessing to reduce set-up time and help with troubleshooting
  • Available for pre-diluted chemical systems (#910910)
  • See more foam/spray bar units in Catalog 10
