The SUNAIR cooling gun system provides a low-cost, reliable, maintenance-free solution to various industrial local cooling problems. The cold air gun uses vortex tube technology to generate low-temperature cooling from compressed air as low as -34  ℃ (-50  ℃ temperature drop). air for many industrial local cooling applications. Since there are no moving parts to wear out, maintenance-free operation is required. The cold air gun requires no electricity, only a source of compressed air, with air consumption ranging from 15 SCFM to 40 SCFM. The cooling gun is very convenient to use. Its permanent magnet base is easy to install and can be placed in any position. The flexible bending of the universal hose (single-head and double-head) used for cold air delivery can deliver the cold air flow to the areas that need cooling. any position.

Cold air guns are often used for cooling metal parts and are used for processing and polishing metal, plastic, wood, ceramics and other materials. Cold air machining outperforms spray coolants and significantly increases tool life and feed rates in dry machining operations. Effective cooling from a cold air gun eliminates heat-related part growth while improving part tolerances and surface finish quality. Cold air guns have adjustable temperature and flow settings; some models have a frost-free nozzle to eliminate the mess caused by frost and condensation.

Cold air guns can provide cooling applications for important and harsh industrial environments. The cooling guns are made of very strong stainless steel and are precision machined, assembled and tested under strict quality control. When used in an environment with coolant, water or other corrosive substances, the surface of the cooling gun will not be dented or corroded or rusted, and the cooling performance will not be affected.

The SUNAIR adjustable cooling gun uses a vortex tube to turn ordinary compressed air into two low-pressure airflows, hot and cold. The hot gas flow is reflected by the suppressor, and part of it is discharged from the hot gas outlet 3. The cold air flow is discharged from the universal hose 4, and the flexible tube is directly directed to the parts that need to be cooled, immediately cooling the heating components. The cooling gun comes with a magnetic base 5, making it very easy to install. The adjustable cooling gun is equipped with a temperature control valve knob 2. When the knob is turned counterclockwise, the cold air temperature will be lowered. At this time, the cold air temperature will decrease and the cold air flow rate will decrease. Turning the knob clockwise will increase the cold air temperature and the flow rate will increase. .
