Information gathered from Aerzen's Literature on this model : The core of this package is the well known Aerzen VM Oil-Free rotary screw compressor.  Aerzen has been making screw compressors since 1943.  The compressor housing is air cooled for highest reliability.  The steel rotors are machined to final tolerances without need for coatings, which are temporary in nature.  The conveying chamber is completely dry.  Clearances between rotors are maintained by the timing gears.  Since compression is accomplished without oil lubrication, there is no possibility of oil contamination of the process steam.  With a huge service life, it is not unusual to find Aerzen screw compressors still in service after decades.
