The Aerzen screw compressors distinguish themselves by two different rotor profiles, which is a criterion which is so far unique on the market for screw compressors.
In vacuum operating the VM compressors can be used up to 80% vacuum (0,2 bar abs.) designed as 4 + 6 profile.
The compressor design VML is a 3 + 4 profile. It can be used up to 70% vacuum (0,3 bar abs.), as special design (pre-inlet machine) up to 85% vacuum (0,15 bar abs.).
Further sizes and designs in preparation, available as existing Delta Screw series.
