Versatile Spot Cooling in Tight Spaces
The Mini Cold Air Gun is designed for applications where the standard Cold Air Gun is too large to fit, or where compressed air flow is limited. The Mini Cold Air Gun uses only 8 SCFM of compressed air and achieves temperatures as low as 0 deg F. The Mini Cold Air Gun is available with a single nozzle or a dual point nozzle for multi-directional cooling.
Cold Air Guns use vortex tube technology and filtered compressed air to produce sub-freezing air as low as -30 deg F for numerous industrial spot cooling applications. With no moving parts to wear out, Cold Air Guns require no electricity at the target, just a compressed air source.
Cold Air Guns are most often used for cooling of metal parts, in the machining and repair of metals, plastics, wood, ceramics and other materials. Cold air machining outperforms mist coolants and substantially increases tool life and feed rates on dry machining operations. The effective cooling from a Cold Air Gun can eliminate heat-related parts growth while improving parts tolerance and surface finish quality.

Mini Cold Air Gun Keeps Blades Cool for Over 20 Years
Mr. Allen purchased a used surface grinder to grind the knife blades. He saw that the grinder did not have anything to contain the liquid coolant that is normally used in surface grinding applications. He did not want to deal with the mess of liquid coolant all over his equipment (not to mention the hassle of disposing of it) so he started looking for an alternate solution to replace the liquid coolant...
