EXAIR Corporation has introduced a new Cold Gun Aircoolant System that protects tools on operations that create excessive heat and eliminates mist, slips, and coolant costs. The Cold Gun is a low-cost alternative to expensive mist systems and eliminates the ongoing costs associated with liquid coolants. It incorporates a stainless steel vortex tube that converts compressed air into a cold 54°F (30°C) air stream at one end and a hot exhaust at the other. The system now features an improved muffler on the hot air exhaust to reduce noise levels. It is non-adjustable to prevent freeze-up during continuous use and is ideal for machining applications.
