Cooling Only PAC with Vest

Product Overview

Workers in extreme temperatures wear Personal Air Conditioners (PACs) to minimize cold stress and fatigue. Another important use is to improve comfort and productivity. This PAC uses vortex tube technology to provide cold air relief and protection to workers in hot environments. This vest helps to minimize heat related injuries and allows the worker to be cool and productive while eliminating the need for costly, unproductive cooling breaks.

  • Temperature adjustment knob provides easy temperature control, even with gloved hands.
  • Available in two different cooling capacities;1500 - 2500 BTU/hr.

September 2021 Update:

The Personal Air Conditioner Vest is currently undergoing a new design. As the old style vest is phased out, you may receive the new style cooling vest depending on size selection. The cost, effectiveness, and efficiency remains the same for the new style vest and the comfort is enhanced! If you have any questions, please let us know at

Personal Air Conditioners

Workers in extreme temperatures wear Personal Air Conditioning Vests to minimize heat stress, cold stress and fatigue, and to improve comfort and productivity. Cold (or Warm) Air circulates through a Diffuse Air Vest to distribute cooling (or heating) to the wearer's torso and neck. The air supplied to the vest achieves a temperature differential of 45 - 60 F° from the inlet compressed air temperature.
