Aerzener Maschinenfabrik GmbH

- Model VMY Series - Oil-Injected Screw Compressors


The synthesis of over 40 years experience and advanced concepts within the compression technology. AERZEN Screw Compressors VMY are oil injected and the ideal choice for a whole range of process gas and industrial applications, where reliability and low operating costs are prime requirements. The oil injection makes the compressor insensitive to fluctuating volumes, temperatures and pressures. Further fields of application: compression of biomethane or biogas on request. The VMY-compressor is a machine with downward delivery. The rotors are positioned horizontally in the housing, the profile is a 4+6-profile. The male rotor directly drives the female rotor; there are no timing gears.
