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

Suitable for independent Class A, B, and C liquid storage areas and affiliated Class A, B, and C liquid storage areas of enterprises with insufficient fire facilities, as well as for fire water supply networks in storage areas shared with other equipment, no additional piping is required.

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, thereby blocking air and achieving fire extinguishing.
