In order to use the compressor in complete safety read the safety standards given in
section 1.3. before reading this section..

Preparing to use the compressor
5.1.1
Operational principle
The air taken-in by the filter passes through a valve that controls its flow rate to the screw where, mixing with the oil, it
is compressed.
The air/oil mix produced by compression reaches a tank where the initial separation by gravity is achieved; as the oil is
heavier, it settles on the bottom, it is then cooled and sent through a heat exchanger, filtered and injected into the
screw again.
(The temperature is kept under control by an electric fan that is directly controlled by a thermostat).The oil is required to
reduce the heat produced by compression, to lubricate the bearings and to maintain the coupling of the screw lobes.
The air is sent through an oil separator filter to be additionally purified from residue oil particles. It is cooled by means
of another heat exchanger and is finally outlet to be used at low temperature and with acceptable oil residues
(<3p.p.m.). A safety system controls the crucial points of the machine and points out any abnormal conditions. The
temperature of the air/oil mix at the screw outlet is controlled by a thermostatic probe placed into the Start/Stop button
(single-
phase ver.) or by “F1” thermal relay placed into the electrical cabinet (three-phase ver.), which stops the
compressor if the temperature is too high.
