Design and technical characteristics

DV-Series screw oil-filled compressors produce industrial compressed air, up to class 4-4-4 to ISO 8573-1:2010.
New compressor design: Professional controller (A), Effective and reliable electric motor (B), Screw air-end (C),
Effective separation system (D).

Controller v-Log (A)

The professional controller v-Log controls A D
operation of the compressor in automatic
mode, and also provides the user with
necessary information on the working

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