Cooling gun is also called tool cooling gun, vortex cooling gun, jet cooling pipe, stainless steel cooling nozzle, cooling nozzle, cooling nozzle, vortex cooling pipe, partial cooler, dry cooler, etc. The compressed air enters the vortex generator of the cooling gun, generates a vortex, and then separates the hot and cold air. Among them, the cold air efficiency ratio is as high as 80%~90%. For many dry air cooling types that require rapid cooling of small areas, Applications, such as machine tool head cooling, various tool cooling, as well as electronic component cooling, welding parts cooling, heat sealing parts cooling, etc., the vortex tube cooling gun can fully meet the needs and is an ideal refrigeration tool. JESON standard cold air gun comes standard with cold and hot end mufflers, single-head universal hoses, magnetic seats, air inlet joints and other devices. It can be directly sucked on the machine tool or metal table and used after passing in compressed air. It is suitable for insulators. Most dry air-cooled industrial applications require rapid cooling of small areas. The cold air gun can also be equipped with air oil and water filters, double-head universal air pipes, air switch valves, etc. There are two series of fixed temperature air guns and adjustable temperature air guns.
