Oil free compressor doesn't require oil separator whereas flooded screw compressor require oil separator. Please let me know the lubrication procedure for both bearings and the screw for both type of compressor. I understand oil free compressor doesn't need lubrication of screw as timing gear take care of the proper screw clearance.
In flooded compressor is the same oil used for lubrication of screw is used for bearing lubrication? Please clarify.
