A motor driven fan having a plurality of annular disks carried by a drive shaft of the motor in closely spaced, parallel relationship. At relatively high motor speeds, bodies of air between the disks are sheared from boundary layers of the air adhering to the sides of the disks and expelled radially outward by centrifugal force acting on them. An annular plate carried by the disk assembly has a cylindrical skirt encircling the disk peripheries which deflects air expelled from between the disks toward the motor to cool it.
