Cold Air Guns for Spot Cooling

Cold Air Guns,Spot Cooling,Cold Air Gun,Pelmar EngineeringCold air guns for spot cooling use filtered compressed air (80-100 PSIG) and vortex tube technology to produce sub-zero air for industrial spot cooling. Cold air machining eliminates mist coolants and heat-related parts growth while improving tool life, parts tolerance and surface finish quality.

Cold Air Guns Applications:

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

Application Videos

  • Frost-Free Cold Air Gun: See how the frost free Cold Air Guns, models 611, 621 & 631, eliminate the mess of frost and condensation

  • Cold Air Gun In Use: Vortec Cold Air Guns cool the tow (resin impregnated graphite fiber composite tape) to prevent adhesion prior to lay-up on MAG’s Viper® Fiber Placement System.

Cold Air Guns provide effective spot cooling for most dry machining operations, allowing increases in feed rates and extending tool life. With no moving parts to wear out, the internal vortex tube converts factory compressed air into a sub-zero air stream, producing temperatures down to as much as -30°F.

  • Widely used in milling, drilling, turning and other metalworking operations
  • Machining of plastics, composites, wood and other materials
  • Surface grinding, drill and tool sharpening
  • CNC routers, blades and band saws
  • Spot cooling of parts, molds and assemblies
  • Industrial sewing and textiles
  • Setting hot melts and adhesives

Spot Cooling Cold Air Gun Models include:

  • Adjustable Cold Air Gun – Our most popular and versatile model.
  • Cold Air Pistol – Offers an ergonomic, easy to use and less costly alternative to the Cold Air Gun for intermittent spot cooling.
  • Mini Cold Air Gun- Its compact size allows close positioning on grinding operations.
  • Thread Guard® – Keeps sewing needles cool to reduce breakage and thread burning.
  • Hot Air Gun – Spot pre-heating
    (up to 200°+ F) of parts and processes, using no electricity.
