Abstract: A powered fastener driver including a housing defining a cylinder support portion with a cylinder and a motor housing portion. The driver includes a piston and a driver blade. The piston is movable within the cylinder from a top-dead-center (TDC) position to a bottom-dead-center (BDC) position with a blade attached thereto for driving a fastener. The driver includes a lifter for moving the piston and blade, in unison, from the BDC position toward the TDC position. The driver includes a nosepiece from which the fastener is discharged, a motor disposed in the motor housing portion, a fan coupled to the motor to receive torque therefrom, causing the fan to generate an airflow, and a conduit for directing the airflow to at least one of away from the cylinder to clear and/or prevent debris accumulated in the cylinder support portion of the housing, or toward the cylinder for cooling the cylinder.
