Abstract

A power tool includes a power tool housing including a fluid inlet and a discharge outlet. A motor is supported by the power tool housing. A tool is configured to be moved relative to the housing by the motor. A fan is configured to be rotated by the motor, such that a fluid flow with debris generated by movement of the tool is drawn into the fluid inlet and through the discharge outlet. A filter is removably attached to the power tool housing. The filter includes a filter media configured to separate the debris from the flow of fluid. The filter media includes a collection container configured to store the debris. The filter also includes an opening in the filter media through which the flow of fluid with the debris enters the collection container, and a valve that is moveable between a closed position and an open position.
