Overview
Designed for 2.2–5.5 GPM pressure washers. The Model 20 Stainless Steel Hose End Airless Foamer is an airless foam applicator for quickly diluting and applying foaming chemicals. This venturi unit draws and blends chemical concentrate into the water stream to create an accurately diluted solution. The solution then flows through 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.
