Electric motor
One of the fundamental parts of the compressor: the motor transfers the motion to the pumping unit through the belt. The 5.5 three-phase electric motor is available on this model. kW.

Stand-alone filter system with Hyperfilter
The filter system, with activated carbon cartridge, is mounted on a stand-alone stand and includes:
- Safety valve (variable according to customer’s request)
- Pressure maintenance valve
- External Hyperfilter and separator kit
- Leg kit
- Automatic condensate drain. Removes water from the intermediate separator and the final separator automatically during operation (every 7 minutes).

Compressor control and automatic condensate drainage system
- Motor protection switch.
- Autostop + Autostart.
- Drainage of the separator between individual stages during compressor operation (standard drainage interval every 15 minutes for a period of 6 seconds).
- Interstage pressure gauges display the working pressure for the individual compression stages. This pressure information allows you to check the tightness of the valves (inlet and outlet) of each stage and to quickly identify potential sources of failure.
Interstage pressure gauges are mounted in the compressor frame.
