Air Jet Nozzles for Polar paper cutters: these are 30mm (1.18") long, including the height of the protruding ball. These air jets or air nozzles are used in early Polar guillotine paper cutter air tables and air feed tables, Polar jogger tables, as well as in other industrial applications for material flotation. They allow for easy movement of stacks of paper or card stock by allowing the stock to float on a thin layer of air. Once the stock clears the button the air jet closes off to prevent wasting air. They are a press fit in the 15 millimeter diameter reamed holes in the table.
