The outer housing is constructed from Fire Resistant Anti-static (FRAS) fiberglass. The drive hub and guards are of a steel construction. The  three blade impeller is made from FRAS polyurethane and has a unique double function of allowing the air supply to turn the blades, meaning that there is no actual motor, and it also creates the air flow of the fan.  The fan can be used as a stand alone unit or with ducting fitted over the outer housing.\u003cbr\u003e\u003cbr\u003eTwo hanging points are provided so that the fan can easily be mounted with chain or straps from a roof.
