2. GENERAL DATA (continued)
2.3.1 CONDITIONS AT SUCTION
In all cases of use, the compressor inlet suction air must
be filtered in order to eliminate particles bigger than 5 µm.
Compressor functionning under pressure :
The maximum pressure drop at suction must be lower
than 75 mbar.
A clogging indicator device turns red when the filter
needs to be changed.
Vaccum operation (SP version only) :
The maximum vacuum authorised for the intake of the
compressor is -8 bar, since the exhaust is into the
atmosphere. Pressure less than 0,3 bar at the discharge
of the compressor A vacuum breaker must be installed
on the suction circuit in order not to exceed -0,8 bar at
the compressor inlet flange.
The clogging indicator is red during the closed intake
operation. This is normal : after a vaccum operation, the
clogging indicator must be released so it becomes trans-
parent again.
REMINDER :
THE CLOGGING INDICATOR MUST NOT BE RED WHEN
THE COMPRESSOR IS IN PRESSURE OPERATION.
When the compressor is used in vaccum operation,
the temperature of the air that escapes from the
exhaust to the atmosphere may be more than 200°C.
Make sure that the flow of hot air does not cause any
damage to the surrounding elements. If necessary,
provide for protections that prevent operators from
touching the hot parts.
The maximum acceptable temperature at suction as a
function of equipment operating conditions is given in
the § T
ECHNICAL CHARACTERISTICS
.
2.3.2 CONDITIONS AT DISCHARGE
The TYPHON II compressor must be protected by a valve
that protects the compressor against accidental over-
pressure.
See Instructions 1401-E00 MISTRAL B600 TYPHON II
CHECK AND RELIEF VALVE
.
Maximum acceptable discharge pressure : see §
T
ECHNICAL CHARACTERISTICS
.
The pressures correspond to the valve opening start
pressure. In a period of 60 seconds, it is acceptable to
have a pressure of 0,2 bar higher when the valve passes
the complete flow rate.
