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.

Modular air circulator control

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. A J-shaped spray arm is rotatably mounted about an axis generally aligned with the axis of the motor and includes a plurality of spray heads which spray the fan guard and blade from the front and rear. The spray heads are mounted at an angle to create a propulsive force which causes the J-shaped spray arm to rotate on its axis. The cleaning shroud can be secured to the fan, mounted in place without removing the fan guard, fan blade or removing the motor from its mounting.
