Section II - General Description
The oil separator tank (OT) removes most of the oil from the air/oil mixture by centrifugal
action. The oil separator (OS) removes the remaining oil. The oil collects in the lower part
of the oil separator tank (OT) which serves as oil tank.
The oil system has a thermostatic bypass valve (BV).When the oil temperature is below
83 °C (181 °F)(87°C (189° F) for optional high water handling capacity versions), the
bypass valve shuts off the oil supply from the oil cooler (Co).
Air pressure forces the oil from oil separator tank through the oil filter (OF). The oil cooler
(Co) is bypassed. When the oil temperature has increased up to 83 °C (181 °F) (87°C
(189° F) for optional high water handling capacity versions), bypass valve (BV) starts
opening the supply from the oil cooler (Co). At approx. 95°C (203 °F)(104°C (194° F) for
optional high water handling capacity versions), all the oil flows through the oil cooler.
The filtered oil flows into the vacuum pump element (E).
Cooling
The cooling system has an oil cooler (Co).
The fan (FN) blows air over the coolers. This fan is set to run on or off, depending on the
operating conditions, according to a specific algorithm.
Condensate system
When discharge piping is used , water in the discharge air can condense in the piping
and is accumulated in the collector of the outlet pipe, where a drain point (Dr) is
available.
When the pump leaves the factory, this drain point is sealed with a threaded plug, but
can be exchanged by a G1/4” connector with tube to drain the condensate. Preventing
condensate collection in the oil separator will extend oil life.
Consult local regulations, which are applicable for water drainage.
