Personal Air Conditioners (PAC's) use filtered compressed air and vortex tube technology to keep workers comfortable in extremely hot or cold areas.With no moving parts, the Vortex tube forces a simple heat exchange to separate compressed air into hot and cold airstreams.

The small Vortex tube, worn on a supplied belt, is connected to ourDiffuse-Air Vest which delivers continuous cooled or heated air through its perforated, inner lining. Temperature is easily adjusted to 33 ºC above or below the inlet temperature. ITW Vortec PAC's provide effective cooling or heating, and are especially popular for workers in confined spaces or operating in or near:


  • Improves worker safety
  • Eliminates the incidence of worker heat stress or cold stress
  • Reduces frequency and duration of non-productive cooling and warming work breaks
  • Maximizes worker productivity and comfort in extreme temperatures
  • Eliminates the need to air condition large warehouse or shop areas


  • Provide continuous, consistent cooling, unlike ice or gel paks
  • The Dual Action PAC can be easily switched from one mode to the other by rotating the tube and swapping the muffler from one end to the other.
  • Three cooling capacities available in the cooling only mode; heating and cooling model is available at two heat/cool capacities
  • Air is delivered at up to +/- 25 - 33 ºC differential from the compressed air inlet
  • Cooling only version has easy temperature adjustment by user, even with gloved hands
  • All PAC models are supplied with an adjustable waist belt and an Industrial Interchange style quick connect for attachment to the compressed air supply
  • Can be worn under other protective clothing
  • Two vest sizes available to fit all workers, plus a vest extension for varying sizes
  • Vest is impermeable to sweat, dirt and other contaminants; easily cleaned
  • Collar unfolds to deliver air to the neck & faceVest allows full range of motion with no airflow restrictions
  • Vest collar unfolds to deliver air flow to neck and face
  • The vest is made of an abrasion resistant, flame retardant vinyl laminated nylon that is self-extinguishing and has a melting point of 149 °C.

consumes 425 SLMP at 6.9 Bar to deliver cold air with a temperature drop of 16 ºC up to hot air with a temperature rise of 33 ºC.
