2-Way Acid HV Foamer

Model # 972327

The 2-Way Acid HV Foamer is a high volume foam applicator for applying 2 highly corrosive chemicals such as those used to remove concrete and for aluminum brightening. This acid-resistant venturi injection system uses standard city water pressure (40 - 125 PSI) to draw and blend concentrated acid into the water stream to create a highly concentrated and accurately diluted solution. A high volume of 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, extended wand and fan nozzle at distances up to 15 feet (25 feet with zero degree nozzle). Use the chemical ball valves to inject the 2 chemicals separately or simultaneously.

Key Features
  • Achieves strong concentrations up to 3.2 to 1
  • Weaker dilution ratios controlled by precision metering tips
  • Projects a high volume of rich, clinging foam which increases chemical contact time and effectiveness
  • Foaming expands the chemical and reduces over-application by providing visual assurance of coverage
  • 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
  • Fan pattern nozzle for quick coverage (up to 15' range)
  • Zero degree nozzle for up to 25' foam throw
  • Adjustable foam consistency (wet/dry) with a concealed air regulator to discourage unauthorized tampering
  • Corrosion resistant wetted components ensure durability and years of reliable service
  • Available with a low or medium flow rate (#972307-LV, 972307)
  • See other Lafferty acid sprayers and foamers in Catalog 8
