Abstract: The present invention provides an air blaster 100 for removing jammed materials. The air blaster 100 includes a tank 110 filled with compressed air and a dual piston assembly 400 inside the tank 110 for triggering a blast with minimum energy loss and high impact force. The piston assembly 400 includes an inlet piston 320 connected to an outlet piston 250 with a coupling mechanism such that the inlet piston 320 and the outlet piston 250 move in tandem and pressure acting on the inlet piston 320 and outlet piston 250 pushes the assembly 400 towards top of the tank 110 thereby compressing a dampening device/spring 360. The force produced by the instant discharge of air creates a strong blast of air in the tank 110.
