Cold Air Guns

Cold Air Gun Application

Cold Air Guns

Cold Air Guns use filtered compressed air (80-100 PSIG) and vortex tube technology to produce sub-zero air for industrial spot cooling. Cold air machining eliminates mist coolants and heat-related parts growth while improving tool life, parts tolerance and surface finish quality. 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.

Versatile Spot Cooling for Machining, Repair Shops and More

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.

Applications:

Cold Air Guns are used in various industrial processes, fabrication, assembly and packaging as a versatile spot cooling device. Most popular applications involve cooling during the machining of metals, plastics, wood, rubber, ceramics and other materials. Cold Air Guns provide effective cooling for most dry machining operations, allowing increases in feed rates and extending tool life. With no moving parts to wear out, the internal vortex tube converts factory compressed air into a sub-zero air stream, producing temperatures down to as much as -30°F.
