Description of the Machine
TI008G0001
Minimum pressure and non return valve
Compressed air is delivered by the compressor through a valve
ensuring a minimum pressure inside the oil chamber, so as to gua-
rantee smooth operation when the compressor is delivering air.
This valve also prevents the compressed air in the system from
returning to the compressor.
Oil separation
The air/oil separation occurs in different stages and ensures excep-
tionally low oil consumptions.
The main mechanical separation occurs in the oil chamber through
a labyrinth path.
This mechanical separation works via the continuous changes of
direction of the air flow in the labyrinth path.
The last separation occurs through the coalescing filter, removing
the remaining oil vapours from the air.
This particular oil separation system brings to a very reduced oil
consumption. The large size of the filter and quality of materials
ensure a long life of the filter itself.
Electric Motor
The compressor and the electric motor are connected by means of
flexible coupling.
This ensures a perfect alignment, no power absorption, silent ope-
ration and no need for maintenance.
Asynchronous, threephase, 4 poles electric motor, with short circuit
winding:
- class F insulation
- High Efficiency Class
- IP 55 protection degree
- electrical supply according to IEC 38
- voltage/frequency V 230/50 Hz - V 400/50 Hz
V 230/60 Hz - V 460/60 Hz
Cooling Systems
The compressor is complete with two coolers, entirely made of alu-
minium and suitable to cool the oil and the compressed air.
An air flow, produced by the fan placed inside the soundproofing en-
closure, flows through the coolers and removes the heat generated
during the compression phase. The compressed air outlet tempera-
ture is slightly over the ambient temperature.
