A barrel fan for the heavy duty circulation of air at the floor level consisting of a cylindrical tubular housing having a guarded rotating propeller blade therein. The blade is driven by a belt connected to an electric motor located on the lower exterior portion of the housing preferably shielded by a skirt in ventilating communication with the housing interior for motor cooling purposes. The motor is pivotally mounted and a spring interposed between the motor and housing maintains the tension within the belt.

Barrel fan with enclosed motor

A belt-driven fan characterized by its concise axial relationship of components. A shroud includes a planar apron and a tubular throat intersecting the apron. Linear support members attached to the apron support an electric motor and blade assembly bearing structure. The motor is mounted upon a bracket attached to the support members for selective assembly thereon between operating and shipping positions and with the bracket in the shipping position the electric motor is primarily located within the shroud throat.
