A
Compressed
air input The compressed air from the source should be within the following
range:
l
Minimum: 60 PSI (400 kPa)
l
Maximum: 150 PSI (1030 Kpa)
The actual pressure through the eductor is adjusted with the regulator.
You may need to adjust the pressure setting to adapt to different
sampling configurations.
The tubing will be either ¼” or 6mm.
B
Filter (behind
the panel)
C
Regulator Use the regulator to adjust the actual pressure through the eductor.
D
Pressure
gauge Displays the pressure in the eductor.
E
Exhaust The Exhaust fitting uses a larger diameter tubing, ie 3/8” or 8mm, in
order to eliminate any restrictions of the flow.
Note The sound from the gas flowing out the Exhaust fitting can be
very loud if the tubing to the exhaust or vent is not connected.
