ABSTRACT:
A device for producing compressed air arranged to suction air from the atmosphere an increase the pressure of the suctioned air by a turbo-supercharger, to cool the air at high temperature by passing the air through an intercooler and to compress the air to a required pressure by an oil-free screw compressor having an air inlet port connected to the intercooler. The compressed air discharged from the compressor is cooled by coolers and then delivered to a user side.
