Dangers and residual risks
During the design phase all hazardous
have been considered and, therefore, all
necessary precautions have been taken
to avoid risks to people and damage to the
machine components.
To guarantee both health and safety of
those exposed, the machine is equipped
with appropriate safety devices:
EMERGENCY push-button to
immediately stop the machine and
STOP devices on the push-button
panel of the control device.
Fixed guards: These are mounted in
areas for exclusive access for standard
maintenance. They are fixed with
systems that require specic tools to
remove them or have been screwed in.
Protection and segregation of the
electrical/electronic equipment of the
machine with a metallic container
to avoid accidental contact with the
equipment under voltage in the event
that the metallic container is open;
protection of the electrical cabin: IP
64; protection of inner equipment IP 20
against accidental contact.
Adequate panels or protections to cover
moving elements.
Electrical devices to detect supply failures
of the machine and the malfunction of
electrical devices of motors.
WARNING!!!
Our machine IS NOT SUITABLE
for use in areas with potentially
explosive atmosphere.
After having carefully considered all
possible risks concerning the use and
maintenance of the machine, the solutions
necessary to remove the risks and limits
the dangers to those exposed have been
adopted.
Although the machine is equipped with
safety devices, the following residual risks
remain:
• Risk of bruises, tearing, cuts during the
handling of tools and/or elements.
• Risk of bruises during machine
intervention.
They can be eliminated or reduced by the

2.02
TI013G0008
application for which it is designed (air
compression for industrial use).
Before starting, ensure that compressor
is filled with oil.
Please refer to Section 8 of this manual
for the oil type to be used.
Never operate the compressor if there is
a possibility of inhaling smoke or toxic or
flammable vapors.
Never operate the compressor at higher
pressures than those indicated in the id
plate.The air delivered by the compressor
must not be used for breathing, unless it
is filtered and purified from oil.
If hoses are used to distribute the air,
ensure they are properly sized and
suitable for the operating pressure, and
not damaged or worn. Please remember
that rubber hoses should be replaced at
regular intervals.
Never remove the oil filler plug when
the machine is running or there is still
pressure inside the compressor: as hot
oil may spray out.
Although it has an acceptable sound
pressure level, the machine can produce
a much higher noise if the room is narrow
and reverberating. Please note that the
continuous presence of an operator is
unnecessary. For safety against noise, in
compliance with local laws in force, and if
necessary, place specific warning signs
near the machine and equip personnel
with suitable protections
Installation
Besides fulfilment of rules and
regulations issued by the authorities,
it is recommended to consider the
following:
The compressor will perform most
efficiently if installed in a suitable area
that is well ventilated and far from
sources of heat.
Should any duct be installed for the
suction and cooling of air, always use
the data and recommendations given in
Section 4 and preferably obtain expert
advice during the design stage.
In the event of outdoors installation
(discouraged in very cold climates), the
machine must be placed under a canopy
or a cover to protect it from atmospheric
elements.
Be most careful to prevent any foreign
material from clogging the radiator,
thus provoking surges in the operating
temperature.
The intake air must be cleaned and free
from flammable vapors that could cause
fires or explosions.
The control and safety devices should
never be tampered with.
If there are one or more compressors
installed on one pneumatic line, it is
absolutely necessary that each be
supplied with an isolation valve.
The electrical connections should
comply with the regulations in force.
The machines should be connected to
the ground and protected by a magneto-
thermal switch against possible short
circuits.
It is absolutely necessary that a power
disconnect switch be installed near of the
compressor.
Maintenance
The person responsible for
operation of the compressor
should check periodically that all
instructions for operation and maintenance
are followed by the operator.
Only trained staff should carry out
maintenance, with the compressor off
and with internal pressure relieved. Also
isolate the compressor from the pneumatic
equipment.
Disconnect and lock out the main power
supply.

OPERATING PRINCIPLE
The design consists of a functional sound-
proofing enclosure made of sheet steel and
painted with epoxy powders.
The enclosure is complete with a pre-
filter kit, preventing the access of coarse
particles, which could clog the radiators
and the air filter before their life-time.
Wide removable panels and hinged doors
make all maintenance operations easily
accessible.
The base is supplied with openings that
allow for easy lifting and handling of the
compressor (See Section 4).
Standard packaging includes: fixing on
wooden pallets and a cardboard box.
The Compressor
The vane compressor is a volumetric rotary
compressor consisting of a cylinder, called
stator, within which a rotor turns, which is
mounted eccentrically and at a tangent,
and by two covers. The rotor is provided
with longitudinal grooves within which the
vanes slide that are kept in contact with the
stator by the centrifugal energy.
Sealing, cooling and lubrication of all
moving parts are guaranteed by an
efficient oil injection system that operates
due to the pressure difference between
the compression chamber and the oil
tank. Hence, no pumps are required for
lubricating oil circulation.
An oil film on the inner stator surface
prevents direct contact with the moving
parts preventing their wear.
In the vane compressor there are no axial
forces that push the rotor against the
covers; therefore it is not necessary to
control their position with thrust bearings.
The rotor is supported by a white metal
bearing and a rolling ball bearing.
Air is drawn into the compressor though the
intake filter and intake valve
into the compressor. The air is then
compressed and discharged in a pulse
free stream.
The suction valve
The intake
valve is controlled by a specific solenoid
valve through a hydraulic circuit, driven by
compressed air. It can adjust the quantity of
air taken into the compressor to supply the
line demand.

TI013G0008
Minimum pressure and non-return
valves
The compressed air is discharged from the
compressor through a valve that ensures a
minimum pressure inside the oil chamber
so to guarantee smooth performance when
the compressor delivers air.
The valve also prevents the downstream
compressed air from flowing back through
the compressor.
Oil separation
Oil is separated from the air in several
steps. This allows for exceptionally low oil
consumption.
The mechanical separation – which is the
greater – takes place in the oil chamber
due too reduced velocity.
Final separation takes place via
coalescence filters that remove almost all
oil residuals from the air.
Thanks to this special separation system,
oil consumption is extremely low.
The large size of filters combined with the
quality of materials used guarantee their
long life span.
Motor
The electric motor is coupled to the
compressor by pulleys and trapezoidal
belts.
The motor is asynchronous, three-phase, 4
or 2 poles, with short-circuited winding.

Cooling and Fan Systems
The compressor comes with two aluminum
radiators suitable for cooling oil and
compressed air, respectively. The cooling
air is drawn in by the cooling fan and comes
into contact with the radiators and removes
the heat generated during compression.
The temperature of the output compressed
air is slightly higher that the environmental
temperature.
See technical characteristics attached.
