ITW Vortec’s dual-action personal air conditioner (PAC) regulates body temperature during all seasons. The PAC is coupled with a lightweight vest, which delivers either cool or warm air to the wearer’s torso and neck. The PAC provides air temperatures ranging from 30°F to 120°F through its vortex tube technology. The diffuse air vests are available in three sizes to accommodate a range of body types. The durable, flame-retardant vest enables full range of motion with no airflow restrictions and will not absorb sweat or other contaminants, the company says.
