Drum Bung Mount Acid Airless Foamer

Model # 972225

The Drum Bung Mount Acid Airless Foamer is a drum-mounted foam applicator for applying highly corrosive chemicals, such as those used to remove concrete and for aluminum brightening, without compressed air. This compact acid-resistant venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend a high concentration of acid directly from the drum into the water stream to create a strong solution. The solution then flows through the discharge hose to the "airless" foam wand which draws in atmospheric air to create and project wet, clinging foam.

Key Features
  • No compressed air required
  • Screws into, and dispenses directly from, chemical concentrate drums for increased efficiency
  • Equipped with both fine and coarse threads
  • Achieves strong concentrations up to 4:1
  • Weaker dilution ratios controlled by precision metering tips
  • Projects wet, clinging foam which increases chemical contact time and effectiveness
  • Foaming expands the chemical and reduces over-application by providing visual assurance of coverage
  • Use it where 35 - 125 PSI water is available
  • Corrosion resistant wetted components ensure durability and years of reliable service
  • Alternate configuration discourages unauthorized changes to the dilution ratio by restricting metering tip access
  • Available as a wall-mounted unit (#972211)
  • See other Lafferty acid sprayers and foamers in Catalog 8


  • Machined polypropylene injector body
  • Stainless steel inlet and PVC discharge ball valves
