Vortec cold air guns use vortex tube technology and filtered compressed air to produce sub-freezing air as low as -30 deg F (-34 deg C) 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. Cold air guns have adjustable temperature and flow settings; and some models have a frost free nozzle to eliminate mess from frost and condensation.
