Designed for 3.5–5.5 GPM pressure washers. The Model 20 SS Bypass Airless Foam/Spray System is a wash/rinse system for quickly diluting and applying chemical and rinsing through the same hose. This venturi unit draws and blends chemical concentrate into the water stream to create an accurately diluted solution. The solution then flows through the hose and gun to the airless foam wand which draws in atmospheric air to create and project wet, clinging foam on to surfaces up close or at distances up to 25 feet with interchangeable fan and zero degree nozzles. Quick connect the fan pattern sprayer nozzle to apply non-foaming chemicals. Open the bypass ball valve to rinse at full volume and pressure.
Model 20 SS Bypass Airless Foam/Spray System (NO HOSE)
Model # 969751
Overview
Key Features
- Designed for use with 3.5–5.5 GPM pressure washers
- Draws chemical out of any container and accurately dilutes to the required ratio (7:1 and leaner)
- Quick connect the airless foam wand to project wet, clinging foam
- Foam increases chemical contact time and effectiveness, and provides visual confirmation 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 the zero degree foam nozzle for increased range (up to 25')
- Quick connect the fan pattern sprayer nozzle to apply a chemical spray
- To rinse at full volume and pressure, simply open the bypass ball valve and quick connect your original rinse nozzle
- Your equipment is protected because no chemical passes through the pump
- Industrial-strength stainless steel construction, with chemical resistant wetted components, stands up to tough conditions and constant use - Built to last!
- Available with two chemical pickups (#969752)
- See other Lafferty high pressure applicators in Catalog 3
