EXAIR'S 1 1/4 NPT Super Air Nozzle delivers 9.4 lbs of strong blowing force when mounted 12 inches away from the target. The force is more than 12 times that of ordinary air nozzles, making it ideal for blowing heavy materials of for applications where the air nozzle can't be mounted close to the surface to be blown off, dried or cooled. The compressed air is ejected through a series of holes located in recessed grooves on the nozzle surface.
