High pressure foam kit for use with all HD/HDS units for efficient cleaning and disinfecting. Foam nozzle connects to lance and the injector kit connects to the high pressure outlet of unit. The injector kit allows for accurate dosing thus reducing chemical consumption. The foam nozzle ejects a thick foam which sticks to the surface to be cleaned. This allows the chemical sufficient time to react and serve its purpose before rinsing. This too will reduce the amount of chemical used thus saving money.
