It is well known that the heat build up on dry machining operations reduces tool life and machining rates. The Cold Gun Aircoolant System from Exair Corp., whose exclusive distributor is Eputec Drucklufttechnik for the DACH region, offers the possibility of concentrate and local cooling. The Cold Gun produces a stream of clean, cold air at 28 degrees Celsius below the supply air temperature.
The Cold Gun incorporate a vortex tube to convert an ordinary supply of compressed air into two low pressure streams, one hot and one cold. The Cold Gun´s hot airstream is muffled and discharged through th hot air exhaust. The cold air is muffled and discharged through the flexible hose, which directs it to the point of use. The easy mounting and portability are provided through the use of an attached magnetic base.
