Abstract:
1. A device for compressing and cooling breathable air, said device comprising: a housing having arranged therein a compressor and a motor operatively connected to drive the compressor; the compressor comprises a compressor housing with a compressor cooling fan mounted at a first end of the compressor housing, the compressor cooling fan being arranged to draw a first flow of cooling air into and through the interior of the compressor housing to cool the compressor, the first cooling air flow exiting the compressor housing and into a first heat exchanger in fluid communication therewith; the motor comprises a motor cooling fan, the motor cooling fan being arranged to draw a second flow of cooling air across the motor to cool the motor; a second heat exchanger sealingly connected to the motor cooling fan, whereby the second flow of cooling air drawn by the motor cooling fan must necessarily pass through the second heat exchanger; a first inlet pipe arranged to introduce an ambient breathable air to the compressor, the compressor being arranged to compress the air; a second pipe arranged to lead the compressed air from the compressor to the first heat exchanger; a third pipe arranged to lead the compressed air from the first heat exchanger to the second heat exchanger; and a fourth outlet pipe arranged to lead the compressed air out of the housing, the compressed air being available to a user via the outlet pipe.
