Hawk offers a range of chemical injectors (venturi injectors) which are ideal for foaming applications.
The operator is applying chemical, in the form of foam, to a surface using a foaming lance and a chemical injector (venturi injector) connected to a high pressure washer.
This is an effective way to apply detergent for de-greasing applications. The chemical injector sucks up a metered amount of soap and sprays it out through the foaming lance.
This system creates a wet foam. For a thicker foam which will hang on vertical surfaces for longer periods of time, compressed air foamers are also available.
Cleaning applications which require foaming systems include car wash, truck wash, poultry house cleaning, industrial cleaning, factory cleaning, piggery cleaning, abattoir cleaning and many more.
