A water-cooled oil-free air compressor which features compactness and ensures improved productivity and maintainability. The compressor is an oil-free screw compressor which includes a low pressure stage compressor body, an intercooler for water-cooling the compressed air discharged from the low pressure stage compressor body, a high pressure stage compressor body for further compressing the compressed air cooled by the intercooler, and an aftercooler for water-cooling the air discharged from the high pressure stage compressor body. The intercooler and aftercooler each have a plurality of units, all of which are almost equal in shape. A cooler header on each or either of the inlet and outlet sides for compressed air is shared by the units of each cooler.
