Product Introduction
PF series high expansion foam generator is the foam equipment of high expansion foam fire extinguishing system, which is mainly used for fire extinguishing systems requiring full flooding and partial coverage. The high expansion air foam generator is composed of foam nozzle, foam net, cylinder and shroud, fan impeller, etc.
Product Introduction
Type description
Working principle
When the foam mixture is rotated by the water turbine of the high expansion foam generator, it is atomized and sprayed by the foam nozzle and intercepted by the foaming net to form a layer of mixed liquid film. The fan impeller rotates and generates airflow to blow the mixed liquid film on the blowing net to bubble, forming a large number of foam to cover the protection object.
