Vortec Cold Air Guns use filtered compressed air and vortex tube technology to produce sub-zero air. With no moving parts to wear out, the internal vortex tube converts compressed air into a cold air stream, producing temperatures down to -30°F (-34°C). With adjustable temperature and flow rate settings, users can customize the output to their specific application needs. By utilizing air-cooling technology, the Cold Air Gun eliminates the mess and expense of liquid coolant and helps avoids secondary parts cleaning after machining.

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.

For a more comprehensive solution, the Cold Air Gun can be purchased as a system that includes a magnetic base and a 5 micron auto-drain compressed air filter.
