Safety devices
Oil Level Display
The oil sightglass enables regular checks for
correct oil level (1).
Exhaust Valve
The “exhaust valve” protects the compressor
in case of air overpressure inside the
chamber limiting its value to the preset
value (2).
Anti-condensate valve
The anti-condensation valve extends the
compressor operation by bringing the oil
temperature up to the setting value of
the thermostatic valve, to avoid moisture
contained in the intake air condensing
on the surfaces and accumulating inside
the compressor. In this way all the intaken
moisture remains under the gaseous state
and is then expelled with the compressed
air. The anticondensate system operates
only when required. (3).

Pressure switch
All versions are
equipped with
a pressure
switch. Its
function is to
keep the
system
pressure within
a preset range
(7,5 – 10 bar).
When the
pressure value
decreases under the minimum setting value
the compressor is set to operation.
When the pressure value increases over the
maximum setting value the compressor is
switched o.
!
WARNING!!!
For suitable operation of the
anti-condensate valve, for no
reason should the pressure
switch setting xed during the factory
testing be modied.
For further information please contact
Mattei’s nearest SERVICE CENTRE or
distributor.
Safety Thermostatic Switch in Case of
Compressor High Temperature
The compressor is equipped with a
protection thermostat in case of high
temperature of the air-oil mixture: this
thermostat detects the temperature at the
outlet of the rotor-stator assembly. This
protection device stops the compressor
as soon as the oil temperature reaches
110 °C. Before restarting the compressor,
identify and resolve the cause of the over
temperature.
