Vacuum connection
Without purge device
With purge device
The air inlet valve is calibrated to reset the volume of
the pump to atmospheric pressure.
When the pump is isolated (at inlet and exhaust) the rotor
slow down efficiency is increased.
If the venting time is setted, the reset to atmospheric
pressure takes place when the pump is stopped or when
faults are registered on the controller
(see C 50) .
Air inlet valve is delivered with a DN 16 long nipple not
used in this installation.
Install the valve on the DN 16 fitting of the pump.
The valve must be connected to an inert gas line which
can be for example dry nitrogen (Pressure between 1 and
1.5 bars absolute)
(see B 50 for nitrogen characteristics) .
Connect the inert gas line with a rigid stainless stell or
flexible pipe (ext. diam 1/4“).
See B 50 .
