Design and technical characteristics

A-Series screw oil-filled compressors produce industrial compressed air, optionally with refrigerated dryer, up to
class 4-4-4 to ISO 8573-1:2010.
New compressor design: Professional controller (A), Reliable electric motor (B), Oil separator tank (C), Screw
airend Rotorcomp Verdichter (D) and Comprag made control valves (E).

The professional controller allows a group
mode control via several t-Log controllers
and connection to a higher-level master
controller or a control room via MODBUS.
