of this manual;
– Never operate the compressor if there is a possibility
of inhaling smoke or toxic or ammable vapors;
– Never operate the compressor at pressures higher
than those indicated on the ID plate. The air
delivered directly by the compressor, ltered and
puried from oil, cannot and must not be used for
breathing;
– If hoses are used to distribute air, ensure that they
are of a proper size and adequate to the working
pressure and that they are neither damaged nor
worn. Please remember that rubber hoses should be
replaced at regular intervals;
– Never remove the oil inlet plug when the machine
is running or there is still pressure inside the
compressor: there would be a leak of hot oil;
– Please note that the machine, although it has an
acceptable sound pressure level, can produce a
much higher noise if the room for its installation
is narrow and reverberating. It should be noted

BLADE

General Information - Safety
that the machine does not require the continuous
presence of an operator. For protection against noise,
in compliance with local laws in force, if necessary,
specic warning signs should be placed near the
machine and the sta should be equipped with
suitable personal protective means.
INSTALLATION
Besides observing the rules and regulations set out by
competent bodies, it is recommended to consider as
follows:
– The compressor will perform most eciently 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 5 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 air sucked must be cleaned and free from
ammable vapors that could cause res or explosions;
– As the machine is air cooled, except for versions “R”
(Heat recovery) and “W” (Water cooled), adequate
ventilation must be ensured to prevent it from
overheating and thus avoiding the recirculation of
the expelled hot air;
– 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 a gate 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 knife line switch be
installed in front of the compressor.
MAINTENANCE
The person in charge of the eective operation of the
compressor should regularly check that all the operating
instructions relevant to the operation and maintenance
are followed by the operator.

GENERAL DESCRIPTION OF THE MACHINE
Mattei rotary compressors of the BLADE 15÷22 Series
are the result of years of investments in research and
development, to improve performance continuously,
and at the same be environment-friendly. Designed for
a continuous industrial service, they guarantee constant
performance over time, low energy consumptions,
reliability, functionality, and easy maintenance.
The electro compressor comes complete with all of the
elements described below and equipped with optional
devices. Unless dierently required, the group is
supplied with synthetic oil Mattei Rotoroil F2. For special
lubricant requirements, please refer to Section 10.
Description of the machine

BLADE
3-2 TI215G0010
Description of the machine
All components are eclosed in a soundproong canopy
in sheet stell, epoxy powder painted and lined with
deadening resistant material. The canopy has a pre-
lter to prevent intake of gross particles that might
prematurely clog the radiators and air lter. Wide
detachable panels and hinged doors allow easy access
for all.
The base has openings to allow easy lifting and handling
of the compressor (See Section 4). Standard packing
includes: xing on wooden pallets, protective polythene
cover, and a cardboard box.
THE COMPRESSOR
The vane compressor is a volumetric rotary compressor.
It consists of a cylinder (stator) in which a rotor, mounted
eccentrically and tangential with it rotates, and two end
covers.
The rotor has longitudinal slots in which the vanes slide.
The vanes are pushed against the stator by centrifugal
force.
Sealing of the moving parts, cooling and lubrication are
provided by an ecient injection of oil through proper
ports, due to the pressure dierence between the
compression chamber and the oil receiver. No pump for
uid circulation is needed.
An oil lm on the inner surface of the stator prevents
direct contact of the moving parts and avoids any
wear. In the vane compressor there are no axial thrusts
pushing the rotor against the end covers. Therefore
there is no need for thrust bearings.
The rotor is supported by white metal bearings having a
practically unlimited lifetime.The air drawn in rst passes
through a lter and then through the modulating valve.
The decrease in volume of the pockets formed by the
stator, rotor and vanes produces a continuous, pulse-
free, compression.
INTAKE VALVE
The intake valve, driven by a specic servovalve
through a hydraulic circuit using the same oil as used
for lubrication, adjusts the intake air quantity to the air
system requirements.
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 guarantee 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 dierent stages and
ensures exceptionally low oil consumptions. The main
mechanical separation occurs in the oil receiver.
This mechanical separation works via the continuous
changes of direction of the air low in the labyrinth path.
The last separation occurs through the coalescing lter,
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 lter and quality
of materials ensure a long life of the lter itself.
MOTOR
The compressor and the motor are connected by means
of exible coupling. This ensures a perfect alignment,
no power absorption, silent operation and no need for
maintenance.
The electric motor is asynchronous, threephase, 4 poles,
with short circuit winding.

COOLING SYSTEMS
The compressor comes with two aluminium radiators
and suitable for cooling oil and compressed air,
respectively.
An air ow, output from the fan inside the sound poof
cabin, 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.
INVERTER ONLY “i” VERSION
The inverter (frequency converter) is an electronic
device that can modulate both the voltage and the
frequency of the machine’s mains electrical supply.
