Model 20SS/A-40SS Bypass Airless Foamer / Sprayer

Model # 969751-40

Designed for 3 - 6 GPM pressure washers using a long discharge hose (+100'). The Model 20SS/A-40SS Bypass Airless Foamer/Sprayer is a wash/rinse system for quickly applying chemical and rinsing through the same hose. This stainless steel venturi injection system draws and blends chemical concentrate into the water stream to create an accurately diluted solution. The solution is then projected through the discharge hose and foam wand where it draws in atmospheric air to create wet, clinging foam on to surfaces up close using a fan nozzle. Remove the fan nozzle for longer foam throw distance. Use the spray nozzle to apply non-foaming chemical in a liquid fan pattern spray.  Open the bypass ball valve to rinse at full volume and pressure.

Key Features
  • Designed for use with 3 - 6 GPM pressure washers with long discharge hoses (over 100')
  • Accurately dilutes chemicals to the required ratios and quickly applies them as a spray or wet, clinging foam
  • Foam maximizes chemical contact time and effectiveness and provides visual assurance of coverage
  • Foam impacts at a lower pressure than spray, allowing a pressure washer to be used on more delicate surfaces
  • Use the fan pattern foam nozzle for wide coverage or remove it for increased range
  • To rinse at full volume and pressure, simply open the bypass ball valve and replace your original rinse nozzle
  • Industrial-strength stainless steel construction, with chemical resistant wetted components, stands up to tough conditions and constant use - Built to last!
  • Your equipment is protected because no chemical passes through the pump
  • Available for discharge hoses shorter than 100' (#969751)
  • Available for two chemicals or dilution ratios (#969752-40)
  • See other Lafferty high pressure applicators in Catalog 3
