Model # 910800

The TransFoamer is an "adjustable flow" foam applicator for feeding 4 - 8 foot long foam bars with chemical solution at up to 5.3 GPM @ 40 PSI. This venturi injection unit uses city water pressure (50 - 125 PSI) to draw and blend chemical concentrate into the water stream and creates a wide range of dilution ratios. Rich, clinging foam is created by injecting compressed air into the solution to greatly expand volume and coverage ability. The water, chemical, and air flow can be adjusted "on-the-fly" via needle valves. This versatile unit can be used for both new installations and to retrofit existing foam bars.

Key Features
  • Designed to feed existing foam bar installations or optional Lafferty foam bars 4' to 8' in length
  • Creates rich, clinging foam which increases chemical contact time and effectiveness
  • Water, chemical and air flow can be adjusted during operation to fine tune settings based on results
  • Precision metering tips allow for more refined control of the chemical flow rate
  • Adjustable foam consistency (wet/dry)
  • Foam bars can be positioned vertically, horizontally, at an angle or grouped in an arch for all around coverage
  • Chemical resistant wetted components ensure durability and years of reliable performance
