Uni-Body Combo Demo Foamer / Airless Foamer / Sprayer

Model # 975540-DEMO

The Uni-Body DEMO Foamer is a combination foam / spray applicator for demonstrating foaming or non-foaming chemicals being applied to any surface. This venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend chemical concentrate into the water stream to create an accurately diluted solution. Use the foam wand and nozzle for rich, clinging foam 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 12 feet. Use the airless foam wand to demonstrate wet, clinging foam without compressed air or use the spray nozzle to apply chemicals as a fan pattern spray.

Key Features
  • Compact and cost effective machined solid polypropylene uni-body design
  • Easy to transport, install, and uninstall
  • Ideal for demonstrating different methods of chemical application to help decide which type of equipment is ideal for a particular situation
  • Creates a medium volume of rich, clinging foam with compressed air
  • Creates a medium volume of wet, clinging foam without compressed air
  • Creates a fan pattern spray for non-foaming chemicals without compressed air
  • Quick disconnects on all wands the user to easily switch between air-assisted foaming, airless foaming, and spraying
  • Dilution ratios controlled with precision metering tips
  • Water and air pressure gauges eliminate guessing to reduce set-up time and help with troubleshooting - very useful for teaching equipment operation
