Abstract
A battery powered tool includes a housing containing a motor assembly. A fan positioned in the housing is rotated by the motor assembly. The fan has a circular ring/body and further has multiple fan blades directly connected to the circular ring body. The circular ring/body defines a concave shaped surface having the fan blades directly connected to the concave shaped surface. A housing cover includes: first and second extending walls; a slot created between the first and second extending walls; and multiple air intake vents all positioned in a lower housing zone separated from an upper housing zone by the slot. An electronics module is positioned in the housing proximate to the housing cover lower housing zone such that air entering the intake vents passes only through the lower housing zone and past the electronics module to cool the electronics module before entering the fan.
