Abstract: The modular timer for an air circulator comprises a timer for energizing an air circulator motor for a predetermined amount of time. A first connector connects the timer to an air circulator motor while a second connector connects the timer to a power switch. A selection switch controls the timer setting of the timer such that the time period corresponds to at least one time period of a work shift. A housing limits access to the selection switch and protects it.

Abstract: A fan cleaning system includes a fan having a motor mounted to a support structure. A fan blade is mounted to a shaft of the motor and enclosed by a fan guard. In one aspect of the invention, the fan guard comprises a front guard and a rear guard having an upper rear guard and a lower rear guard. The upper rear guard and lower rear guard are mounted to the motor on opposite sides of the motor and shaft thereby permitting removal of the upper and lower rear guards from the motor without removing the fan blade. In a second aspect of the invention, fan cleaning system includes a cleaning shroud which completely encloses the fan guard, blade and part of the motor. The cleaning shroud preferably comprises an upper shroud and a lower shroud and an upper shroud bracket and a lower shroud bracket sealingly mounted against the motor.

Abstract: An industrial electric fan motor has a remote hand set in which both a switch and a motor capacitor are disposed. The remote hand set is connected to a casing of the fan motor by a control cord with a selectively engageable plug. The switch and the capacitor are serviced by disconnecting the hand set from the motor by unplugging it and plugging in a replacement remote hand set.

Abstract: A fan comprises a pair of guard halves which surround an impeller. One of the guard halves is smaller than the other guard half, such that the smaller of the two may be stacked within the larger to reduce the required space for packaging. Due to the inventive construction, the required space for packaging the guard is substantially reduced over prior art structures which have guard halves of approximately equal dimensions. Further, an inventive packing structure is disclosed wherein the individual components of a guard/impeller subassembly are securely packaged relative to each other. In particular, an impeller is positioned within the stacked guard halves, and secured at a relatively fixed positioned by resilient packing materials. The guard halves are preferably formed by a number of radially and circularly extending wires. A plurality of foam blocks are spaced in the stacked guard halves, at positions spaced from the impeller.

Abstract: A modular motor end dome for an industrial electric fan motor has a motor capacitor, and is provided on the rear end with a protective axial cavity in which may be seated the threaded mounting stem and attachment nut of an internally mounted pull chain electric motor control switch. Alternatively, an external 2-speed electric motor control switch can be employed with the modular motor end dome and with a drop cord connecting the external 2-speed electric motor control switch to the motor capacitor mounted in the modular motor end dome, and with the drop cord entering the modular motor end dome through the protective axial cavity.

Abstract: A hinged and quick mount guard for an electric fan. The fan guard includes a concave, dish-shaped rear guard member having an axial opening for the reception of a fan motor shaft, and a plurality of key holes for the reception of thru-bolts on the fan motor for securing the rear guard member to the fan motor. The fan guard includes a concave, dish-shaped front guard member hingedly and releasably retained on the rear guard member.
