Cold air gun

The high-power cold gun incorporates a stainless steel vortex tube that converts ordinary supplies of compressed air into cold air. The air gun produces a stream of 20 F air to reduce heat buildup from laser cutting, and a flexible ball-and-socket hose holds its position to direct the cold air to the point where the heat is generated.

The high-power cold gun incorporates a stainless steel vortex tube that converts ordinary supplies of compressed air into cold air. The air gun produces a stream of 20 F air to reduce heat buildup from laser cutting, and a flexible ball-and-socket hose holds its position to direct the cold air to the point where the heat is generated. A portable magnetic base facilitates mounting. The air gun can help reduce harmful airborne coolants.
