The ST76 foam blaster made by RM Suttner in germany is an extremely powerful foam gun. The gun has three air injector nozzles incorporated into its body which can be changed to suit the flow and pressure that the user is operating at. This product is great for applications in agriculture, fire fighting technology and general cleaning that requires a foam application. There are many benefits to using foam when cleaning but its ability to cling onto surfaces for longer help to assist cleaning detergents to penetrate into mud, grease and oils more effectively. The additional time that the foam offers cleaning detergents on surfaces allows them to be more effective. Another benefit from foam cleaning is its visual impact. The user can see exactly where has been treated which can be difficult when simply just spraying a detergent or using water. Foam is used to fight fires that are particularly hard to extinguish, such as flammable liquids. Foam blankets these flammable liquids effectively smothering the fire. It then cools down the fuel or material it is in contact with and supresses the release of flammable vapours. This foam blaster by Suttner is capable of throwing foam up 40 feet which is why this product is great for fire fighting.
