Rotary Screw Air Compressors are offered with reduced differential pressure between flutes that helps decrease back flow increasing adiabatic efficiency. Air Compressors are equipped with rotors that rotate at low speed resulting in decreased noise level. Air Compressors use oil or air tag that allows easy installation and replacement of oil separator. Rotary Screw Air Compressors are provided with fin type after cooler with large pipe diameter, which makes repair and maintenance job fast and easy.
