Large flow rate is a feature of the hangar foam fire extinguishing system, and F+W's self-developed piston pump can achieve the maximum flow rate 3600OL/min, 2 parallel operation can basically meet the flow requirements of all hangars.

Due to the empty pipe behind the proportional mixer, the flow rate will be large when the system starts, and theF+W proportioner has 150% overflow capacity, making the system safer.
