Replace messy mist systems
April 2006
Pneumatics & Hydraulics
A new solution to an old problem. Heat build up on dry machining operations reduces tool life and machine rates. The Exair cold air coolant system produces a stream of clean cold air at 28°C below supply air temperature. Operation is a quiet 70 dBA - and there are no moving parts to wear out. It will remove heat to prolong tool life and increase productivity when liquid coolants cannot be used.
The cold gun is also an alternative to expensive mist systems. It eliminates the costs associated with the purchase and disposal of cutting fluids and worker related health problems from breathing airborne coolants or slipping on wet floors.
The Exair cold air gun is non-adjustable to prevent freeze-up during use. Cold airflow and temperature drop are factory set to optimise cooling capability. It gives instant cold air when filtered compressed air is supplied to it. Cycling on and off is a good way to save compressed air. For manual control the model 9012 Manual Shutoff Valve is used. To turn the cold gun on with the machine, the model 9020 solenoid valve may be used and wired through the machine control switch. This method is suitable for hand grinders and drill sharpeners.
The cold air gun is designed to use full line pressure of 550 to 690 kPa. Temperature drop and flow are reduced when lower input pressures are applied. The use of clean, filtered air is essential to the operation of the cold air gun. A manual drain filter that removes moisture, dirt and other particles from the compressed air is included with each cold gun system.
How the gun works
The Exair cold air gun incorporates a vortex tube to convert an ordinary supply of compressed air into two low-pressure streams. One hot and one cold. The hot air stream is muffled and discharges through the hot air exhaust. The cold air is muffled and discharged through the flexible hose, which directs it to the point of use. The magnetic base provides easy mounting and portability.
