The PC series liquid surface air foam generator is a horizontal fixed fire suppression device mounted on the top wall of an oil tank, capable of generating and projecting air foam. When foam from fire trucks or fixed fire pumps is supplied through the transport pipeline and passes through the foam generator, it forms air foam to extinguish oil fires. The air foam generator is mainly composed of three parts: the foam generator body, the foam nozzle assembly, and the guide plate assembly. As the foam mixture passes through the generator nozzle, it creates a diffused atomized jet, generating a negative pressure around it to吸入a large amount of air, forming foam. The air foam is then projected into the tank through the foam nozzle openings for fire suppression.
