About Foam Injectors and Lances
Foam injectors can make a massive difference to chemical application. By aerating the chemical it creates a foam which will then cling to the surface which is being cleaned for a much longer period of time and therefore improve cleaning results.
This is the method that many valeters use to apply their snow foam but it is also used in the food industry to apply chlorinated foam cleaner and also many farmers use foam injectors and lances to apply disinfectants to their parlour walls.
As with any attachment it is important to get the correct injector and lance size for your machine and for best results they should be used in conjunction with a foaming chemical.
