A powered fastener driver includes a cylinder and a drive piston within the cylinder being acted on by a driving force resulting from a pressure differential. The powered fastener further includes a drive blade coupled to the drive piston and operable to drive a fastener, and an adjustable valve for selectively introducing air from ambient atmosphere into the cylinder, thereby changing the pressure differential acting on the drive piston. By adopting a self-contained vacuum generating means as described above, the present invention does not rely on any external vacuum source and powered fastener driver can be used and carried with conveniently.
