Abstract:
An oil free compressor includes a cooling fan, a low-pressure stage air-cooled heat exchanger, a high-pressure stage air-cooled heat exchanger, and a lubricating oil air-cooled heat exchanger. The cooling fan is provided independently from each of the low-pressure stage air-cooled heat exchanger, the high-pressure stage air-cooled heat exchanger, and the lubricating oil air-cooled heat exchanger.
