Cold Air Guns use a small amount of filtered compressed air and vortex tube technology to produce sub-freezing air for numerous cooling applications. Without any moving parts to wear out, the internal vortex tube converts shop compressed air into a cold air stream, producing temperatures down to as low as -30 degrees F.
Visit the Cold Air Guns website (www.airtx.com/cold_air_guns) to see applications and details. There are many makes and types of cold air guns available. A basic setup can be purchased for less than $150.
