Incredible Spot Cooling for Machining Operations

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.



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

Widely used in milling, drilling turning and other metalworking operations
Machining of plastics, composites, wood and other materials
