EXAIR - Cold Air Gun Aircoolant System

Heat build up on dry machining operations reduces tool life and machining rates.  EXAIR's Cold Gun Aircoolant System produces a stream of clean cold air at 28 deg 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 on machining operations 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.

EXAIR's Cold Gun is non-adjustable to prevent freeze-up during use.  Cold airflow and temperature drop are factory set to optimise the gun's cooling capability.

The Cold 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 airstream is muffled and discharged 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.
