Introduction
Introduction
GA 18 VSD+ up to GA 37 VSD+ are single-stage, oil-injected screw compressors driven by an interior
permanent magnet motor (IPM).
The compressors are controlled by the Atlas Copco Elektronikon® Graphic regulator (ER).
The regulator is fitted to the front panel. An electric cabinet (1) comprising fuses, transformers, relays, etc.
is located behind this panel.
The compressors use VSD (Variable Speed Drive) technology. This means: automatic adjustment of the motor
speed, depending on the compressed air demand.
The compressors are air-cooled and are enclosed in a sound-insulated bodywork.
