3.3 Operating
conditions
Default conditions
Ambient temperature
+20 °C +68 °F
Ambient pressure 101.3 kPa 14.7 psi
Air saturation 50 %
Temperatures
Temperatures of pumped gases/vapours
Intake temperature
max. +60 °C max. +140 °F
Delivery temperature  Ambient temperature
Temperature of operating liquid
max. +60 °C max. +140 °F
Ambient temperature
max. +40 °C max. +104 °F
min. +10 °C min. +50 °F
With ambient temperature < 10 °C (< 50 °F):
Observe yellow adhesive label on cover plate.
Add ethylene glycol to operating liquid in separator
accordingly.
Pressures
Inlet pressure
min. 5 kPa abs. min. 0.725 psia
max. 80 kPa abs. max. 11.6 psia
At inlet pressures > 35 kPa abs. [5.08 psia], the
share of water vapour in the escaping gases may
be slightly above that of the gases sucked in. The
resulting water loss can automatically be
compensated by a feed regulator (see Chapter 5.5,
"Accessories", Pg. 19).
It is prohibited to connect piping to the discharge
side of the system!
Discharge pressure
