Oil-free compressors draw air within a cylinder which is pre-lubricated for permanent lubrication so as it produces identical compressed air quality to that of the intake air which helps the air remain oil-free. They are less expensive, lighter in weight and produce as much air flow (CFM) & pressure (psi) as many oil lubricated models.
