Abstract
A power tool is provided and includes a tool housing having interior and exterior surfaces and inlet and outlet air vents and a motor disposed in the tool housing and having a motor housing with an external surface and inlet air ports for the passage of cooling air into the motor and outlet air ports for passage of warmed exhaust air from the motor. The inlet and outlet air ports open at the external surface and the outlet air ports are spaced from the inlet air ports. The tool also includes an air deflector resiliently coupled to the external surface. The air deflector includes wall structures bracketing the outlet air ports. The structures have portions extending to and contacting the interior surface of the tool housing and bracketing the outlet air vents to form a barrier around the outlet air ports and vents to channel exhaust air to the outlet vents and substantially inhibit exhaust air from the outlet air ports from entering the inlet air ports or other portions of the tool.
