Designed to replace the black soap nozzle on pressure washers that use a factory chemical injector. The A-40 Airless Foam Wand quick connects to a pressure washer gun and injects atmospheric air into the chemical solution to greatly increase volume and coverage ability. This stainless steel unit will create and project wet, clinging foam on to any surface in a fan pattern or zero degree stream for increased foam throw distance.  Foam wands are also used for softwash applications with a low pressure pump.
