2.3.2 Exhaust
The exhaust Fig. 2 /2 flange is located on the side of the PhoeniX.
There is a filter mounted in the exhaust that absorbs the oil steams occu-
ring during the use of the rotary vane pump. The exhaust filter has to be
cleaned when doing the maintenance.
Caution When the Phoenix is running in closed rooms the exhaust has to
be put out-of-doors using the provided adapter. So the oil
steams that are harmful to health are lead off.
With the provided connection a hose line can be connected to the exhaust
of the PhoeniX and lead off.
2.3.3 Vent
Usually the parts under test are vented with ambient air when the test is
finished. If it is required the parts can be vented with a different gas (i. e.
fresh air, dry air, nitrogen, …) at atmospheric pressure. In this case a vent
hose has to be connected to the hose coupling
Fig. 2 /1.
2.3.4 Gas ballast connection
For the mode gas ballast it is recommended to use helium-free gases at
atmospheric pressure. Ambient air can be contaminated with helium due
to
spraying or charging. In this case a gas supply line (i. e. nitrogen, fresh
air, …) should be connected to the hose coupling Fig. 2 /3. The pressure of
these gas line must not exceed 1050 mbar.
The connector 1,2 and 3 in Fig. 2 are quick connectors for hose diameters
of 8/6 mm.
