A pneumatically powered nail gun having a duster mechanism which is also pneumatically powered with the same pneumatic source. The nail gun includes a main body having a lower end and defines therein a compressed air chamber. A cylinder piston arrangement is disposed in the main body, and the compressed air is selectively applied to the piston for moving a driver blade connected to the piston to drive a nail. The duster mechanism includes a duster nozzle provided at the main body for ejecting a compressed air therethrough. A pressure release valve is disposed at an air passage extending between the duster nozzle and the compressed air chamber for selectively shutting off a fluid communication therebetween. A pressure regulating section is disposed at the air passage for providing a compressed air passing through the duster nozzle at a pressure lower than that in the compressed air chamber.
