5 Gallon Internal Tank Foamer

Model # 925905

The Internal 5 Gallon Tank Foamer is a low-volume foam applicator with an all stainless steel cart assembly for applying ready-to-use foaming chemicals. Connect compressed air to pressurize the 316L stainless steel ASME rated tank and to inject air into the solution to greatly increase volume and coverage ability. A low-volume of rich, clinging foam is projected on to any surface up close or at distances up to 9 feet. Each fill provides 10 minutes of foaming time.

Key Features
  • 316L stainless steel, ASME rated tank and all stainless steel wetted components ensure durability and years of outstanding performance
  • Designed for more controlled foaming and extended foaming time in smaller areas
  • Projects a low 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
  • Fan pattern nozzle for quick coverage (up to 9' range)
  • Adjustable foam consistency (wet/dry)
  • Powered completely by compressed air
  • No moving parts, virtually no maintenance required
  • Available with a higher flow rate and 16 or 37.4 gallon tank (#925916, 925937)
