RamFan (Water) WF20 8-Inch (NST/NH Male) Blower / Exhauster (Navy/Military Spec)

RamFan WF20 8-Inch Blower / Exhauster with 1.5 Inch NST/NH Male connection (Australian Navy Specification). No portable blower in the world compares with the smoke removal rates of the WF20. The WF20 blower uses the water pressure energy of a fire hose and a patented turbine, coupled to a high-efficiency fan blade, to generate high-velocity, high-pressure airflow. The modular construction, choice of corrosion-resistant materials and simplicity assures infrequent and simple maintenance.
