Diaphragm Pressure Proportioner
It is a fixed type foam mixing device installed with the bladder bag embedded-type foam tank, and the range of use is more diverse compared to existing mixing devices.
Also, this mixing device is improved with performance to maintain the stable mixing ratio. The diaphragm cylinder is installed in the induction line of the foam liquid on the mixer to control the suction amount appropriately according to the changes in the flux and pressure. Also, the induction is enabled in constant ratio to mix the foam stably in high flux for more effective fire extinguishing.
