ITW Vortec’s vortex tube products have been solving industrial cooling problems for years. Using only filtered, factory compressed air as a power source, they convert ordinary compressed air into two air streams — one hot and one cold. At 100 PSIG (6.9 Bar) and 70ºF (21ºC) inlet temperature, a vortex tube can produce refrigeration up to 6000 BTUH (1512 kcal/H) or temperatures to -40ºF (-40ºC).
Choose one of our Cold Air Guns for quick, easy installation or the model from our complete vortex tube line that best fits the specific needs of your application.
- Cool without refrigerants (CFCs/HCFCs) or moving parts for reliable, trouble-free operation.
- Use no electricity — intrinsically safe, no RF interference.
- Include an integral muffler for quiet operation — within OSHA noise specifications.
- Are powered by filtered compressed air.
Model 620 Adjustable Cold Air Gun
The Model 620 Adjustable Cold Air Gun is ideal for use in machining applications and for cooling parts and industrial processes. Model 620′s adjustable feature allows you to set the cold airflow rate (BTUH) at optimum levels for your application. The Adjustable Cold Air Gun’s maximum temperature drop is 100Fº (55.6Cº) below inlet air temperature and the maximum cooling capacity is 1500 BTUH (378 kcal/H). Model 620′s compressed air supply requirement is 25 SCFM (708 SLPM) at 100 PSIG (6.9 Bar).
Model 620 comes complete with a flexible nozzle for directing cold air and a magnetic base for quick, easy installation and use.

Model 424 Thread Guard® Needle Cooler
Watch your piece rate jump with ITW Vortec’s Model 424 Thread Guard®. Thread Guard delivers a continuous stream of cold air onto the sewing machine needle to virtually eliminate downtime caused by needle breakage and thread burning caused by overheating. It’s effective even in the most challenging sewing operations including belt loops and tough materials. Cooling also prevents holes caused by hot needles burning synthetic fabrics. Model 424′s compressed air supply requirement is 4 SCFM (113 SLPM) at 100 PSIG (6.9 Bar).
