Electric motor

One of the fundamental parts of the compressor: the motor transfers the motion to the pumping unit through the belt. The 7.5 three-phase electric motor is available on this model kW.

Electrical cabinet

• ON / OFF switch with motor protection switch.
• Electromechanical pressure switch that stops the compressor at the final pressure.
• Drainage of all separators between the individual stages and also of the final separator during compressor operation
• Timer for automatic condensate drain.
• Integrated no-load start (automatic drain every time the unit is switched off).
• 5 liter condensate collection tank, with silencer; capacity of about 3 liters, for the ecological disposal of condensate.
• 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.

Chassis

Silenced chassis made for environments that require a low noise level. The oil level and drain reported outside, the control console equipped with inter-stage pressure gauges, the internal temperature indicator, the alarm presence and incorrect phase sequence, the oil lack alarm and the start-stop commands and manual condensate drain allow easy management and maintenance of the compressor.
