Replace messy mist systems - improve dry machining with clean, cold air!

What is the Cold Gun Aircoolant System?

 

EXAIR’s Cold Air Guns use filtered compressed air (80-100 PSIG) and vortex tube technology to produce sub-zero air for industrial spot cooling. Using only compressed air, the Air Gun produces a stream of cold air 50°F (28°C) below your compressed air temperature @ 80 psi. It’s clean, convenient – put the gun where you need it, using the magnetic base – aim the cold air stream onto your work with the flexible hose – go to work!. To optimize the gun’s cooling capability the cold airflow & the temperature drop are factory set & is non-adjustable.Cold air machining eliminates mist coolants and heat-related parts growth while improving tool life, parts tolerance and surface finish quality. Air Cooling System for dry machining applications -

Cold Guns keep parts cool

The Model 5215 Cold Gun keeps the part
cool to the touch and prevents discoloration.

replaces polluting and often toxic mist systems to improve dry machining operations. No mess, no residue and low in cost. The unit is muffled for quiet operation. No moving parts assure long life, maintenance free operation while extending tool life and improving production rates.

Cold Air Guns are used in various industrial processes, fabrication, assembly and packaging as a versatile spot cooling device. Most popular applications involve cooling during the machining of metals, plastics, wood, rubber, ceramics and other materials.

Cool a two flute carbide cutter

The Model 5315 Cold Gun cools a two flute 3/8" carbide cutter on a CNC, increasing tool life by 50%.

Coolant Free Tool Grinding

 

 
Model 5215 Cold Gun System

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.

Flycutter Cooling




Model 5215 Cold Gun System

Milling & 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.

Coolant Free Tool Grinding




Model 5315 Cold Gun System

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.

Coolant Free Tool Grinding




Model 5230 High Power Cold Gun System

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.

  How the Cold Gun Works ?

 

Cold Gun Diagram

The standard Cold Gun and High Power Cold Gun incorporate a vortex tube to convert an ordinary supply of compressed air into two low pressure streams, one hot and one cold. (For complete information on vortex tube operation, see the "Vortex Tubes and Spot Cooling Products" section of this website.) The Cold Gun's hot airstream is muffled and discharged through the hot air exhaust. The cold air is muffled and discharged through the flexible hose, which directs it to the point of use. Easy mounting and portability is provided through the use of an attached magnetic base.
