The Vertical Foam Bladder Tank is a steel pressure vessel fitted with an internal bladder that stores foam concentrate. When the pressurized water flow of the fire protection system passes through this device, the pressure proportional mixer diverts it proportionally. A small portion of the water enters the interlayer of the foam concentrate storage tank with a rubber bladder, compressing the bladder and displacing the foam concentrate. This foam concentrate then mixes with the fire protection water within the pressure proportional mixer to form a foam mixture of the corresponding proportion. The foam mixture is subsequently transported through piping to the foam discharging device, directly performing fire extinguishment in the protected area.
