The PF high expansion foam generator is one of the key equipment for high expansion foam extinguishing system. Its advantage is that it has big frothing volume and can be applied in different cases. Driving a hydroturbine with foam solution whose pressure is from 0.3~1.0Mpa and then the hydroturbine drives the fan. Foam solution was dispersed into droplets when it flow through a nozzle and sprayed to foam generate net. These droplets then form thin films and were blowed into amount of foams by the fan, constituting high expansion foam.
