High expansion foam generator is the key equipment for high expansion foam system. It is of big frothing volume and can be applied in different cases.
Principle
Driving a water turbine with foam solution whose pressure is from 0.3~1.0MPa and then water turbine drives the fan. Foam solution was dispersed into droplets when it flows through a nozzle and sprayed to foaming net. These droplets form thin films and were blown into amount of foam by fan.
