Our Breathing Cold Air Source is a fresh, refrigerated air supply system which provides comfortable and safe cooled breathing air for industrial users who require an OSHA compliant fresh air supply system, with the advantages of air-conditioned air. It can maximize productivity and minimize the possibility of heat stroke, heat exhaustion, dehydration, nausea and cramps for your workers. While our Breathing Cold Air Source improves the worker’s safety and comfort, it also helps reduce their frequency and duration of breaks on the job. This sealed, low maintenance unit includes a removable, washable filter and is powder coated for a longer-lasting durability.
