Cold air guns are also called tool cooling guns , vortex cold air guns, jet cold air ducts, stainless steel air conditioning nozzles, cold air nozzles, cold air nozzles, vortex cold air ducts, local coolers, dry coolers, etc. The compressed air enters the vortex generator of the cooling gun, generates a vortex, and then separates hot and cold air. The efficiency ratio of cold air is as high as 80%~90%. For many dry air-cooling systems that require local rapid cooling of small areas, Applications, such as machine tool head cooling, various cutting tool cooling, as well as cooling of electronic components, cooling of welded parts, cooling of heat sealing parts, etc., the vortex tube cold air gun can fully meet the needs and is an ideal refrigeration tool. JESON standard air-conditioning 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 can be used by passing in compressed air. It is suitable for most applications. Most dry air-cooled industrial applications require local rapid cooling of a small area. The cold air gun can also be equipped with air oil and water filters, double-ended universal air pipes, air switch valves, etc. There are two series of fixed temperature cold air guns and adjustable temperature cold air guns.
