Exair vortex tubes convert an ordinary supply of compressed air into cold and high temperatures with no requirement of refrigerants or moving parts, thereby providing an efficient spot cooling solution in industrial applications. These units are constructed of stainless steel material to provide wear and corrosion resistance against environmental factors. These units meet OSHA noise and pressure requirements and are ideal for use in electronic controls, gas samples, machining operations and environmental chambers for an instant cooling effect in the desired temperature. Selected models (vortex tube kits) include muffler, hose and generators for aiding the cooling process. Choose from a wide range of these vortex tubes, available in 1/4 and 1/8 inch (M) NPT air inlet connections.
