ABSTRACT:
A fan assembly includes a statonary support holding a rotary support operated by a motor for turning 360 degrees about a vertical axis and a plurality of fan units mounted on the rotary support. First conductors are provided to connect the motor and the fan units to rotary conducting plates which respectively contact stationary second conducting plates, and second conductors are connected to the second conducting plates, thereby preventing the conductors of the assembly from becoming tangled.
