  • Patent number: 4251994
    Abstract: A breathing apparatus is provided which delivers cool, air conditioned air to a remote location as much as 100 feet away from the apparatus proper. The unit is powered by an air motor operable from an industrial compressed air tank, and an oil-less pump is driven by the air motor to elevate the pressure of fresh air adequately for remote delivery. Cooling of both the drive air and the respirable fresh air is provided by radiators, and a final cooling stage is incorporated as a heat exchanger which cools the fresh air from the spent drive air, the latter having reached a very low temperature due to the rapid expansion of the air as it passes through the air motor.
