Abstract

A power tool having a power tool housing, a motor, a tool moved relative to the housing by the motor, a fan rotated by the motor such that a fluid flow with debris generated by tool is moved into the fluid inlet by the fan and through the discharge outlet, and a filter that is removably attached to the power tool housing. The power tool housing includes a fluid inlet and a discharge outlet. The filter includes a filter media for separating the debris from the flow of fluid. The filter media defines a collection container for storing the debris. The filter also includes an opening through which the flow of fluid with the debris enters the collection container, and a valve that is moveable between a closed position, in which the opening is closed, and an open position, in which the opening is open. The valve includes a duckbill check valve.
