EXAIR has launched a metalwork cooling system which applies a stream of clean air onto a workpiece.
The Cold Gun Aircoolant System produces cold air at 28 degrees Celsius below the supply air temperature. It also operates at 70dBA and has no moving parts.
The standard model has a vortex tube which converts an ordinary supply of compressed air into two low pressure streams. The hot stream is muffled and discharged, while the cold air is directed to the target through a flexible hose.
The company says the system can be used as an alternative to liquid coolants or mist systems. This eliminates the purchase and disposal of cutting fluids and can prolong the tool’s lifespan.
The unit can be employed to prevent burning, reduce breakage rates, improve tolerance control, dry parts and eliminate heat cracking. It is suitable for cutting, milling, drilling, laser and computer numerical control (CNC) applications.
