Designed to "foam" cleaning agents or disinfectants onto surfaces to be cleaned or sanitized. Used in conjunction with your existing trigger wand and downstream injector. Air pulls into the orifice in the wand handle to mix with the water/chemical flow to create a foam mixture. Stainless nozzle and extension pipe are standard. Inlet is 1/4" FPT. Match air orifice shown to the flow rate of your pump for optimal foam production. Available in either 25" or 48" lengths. Rated to 300 Deg. F. Maximum pressure is 900 psi.
