When the foam mixture supplied by a foam fire truck or fixed fire pump flows through a generator via a conveying pipeline, it draws in a large amount of air to produce foam, which is then sprayed onto the surface of the burning liquid to form a foam layer or film. This is a key component of the low expansion foam firefighting system.

Suitable for independent A, B, C class liquid storage tank areas and auxiliary A, B, C liquid storage tank areas of enterprises with insufficient fire protection facilities, as well as shared storage tank areas with other equipment, no additional pipeline is required for fire water supply.

Structural Features and Working Principle

Structure diagram as follows: Figure 1

Operation Principle: As the foam mixture flow supplied by a foam fire truck or fixed fire pump passes through the generator via the conveying pipeline, it draws in a large amount of air, produces foam, and then travels through the jet pipeline. After being blocked by baffles, it flows down along the tank wall, forming a foam film on the oil surface, which effectively blocks air and achieves fire extinguishing.
