Product Description


What Is a Vortex Tube?

A low cost, reliable, maintenance-free solution to a variety of industrial spot cooling problems. Using an ordinary supply of compressed air as a power source, vortex tubes create two streams of air, one hot and one cold, with no moving parts. Vortex tubes can produce:
  • Temperatures from -50° to +260°F  (-46° to +127°C)
  • Flow rates from  2 to 150 SCFM  (28 to 4,248 SLPM)
  • Refrigeration up to 10,200 Btu/hr. (2,571 Kcal/hr.)

Temperatures, flows and refrigeration are adjustable over a wide range using the control valve on the hot end exhaust.

Why EXAIR Vortex Tubes?

EXAIR Vortex Tubes are constructed of stainless steel. The wear resistance of stainless steel, as well as its resistance to corrosion and oxidation, assures that EXAIR Vortex Tubes will provide years of reliable, maintenance-free operation.

Tool Grinding

Cold air eliminates heat cracking of carbide and tool edge burning during grinding and sharpening operations. Increased tool life between regrinds is the result.

Milling and Drilling

Fly cutters up to 460mm in diameter have been cooled with the Cold Gun. Dissipating heat with cold air extends tool life, increases speeds and feeds, and improves finishes.

Chill Roll

Cooling a roll with 20°F  (-7°C) air keeps the material on the surface from bunching up, jamming or tearing. The metal surface transfers the cold temperature to the product.

Laser Cutting

Cold air cools a laser cut part so it can be handled seconds later. The High Power Cold Gun has twice the cooling capacity of the standard Cold Gun, cooling the part in less time.
