Cold air gun is very helpful for the application of rapid dry cooling of small local area, such as machine tool head cooling, cooling treatment of various cutter tools, electronic components cooling, the cooling of welding and so on, it is an ideal tool for small area cooling. Features: Cold air gun is the cold air source which is easy to carry, it is widely used in mechanical drying or cooling process. It can only use compressed air to lower the air temperature to produce low-temperature airflow. Clean and easy to install, and its flexible universal tube delivers cold air to the location where it needs to be cooled. An important device to provide cooling applications in harsh industrial environments and it can work continuously and stably. It has built-in control valve, thus you can adjust the volume of outlet air and the temperature according to the need.
