MAN B&W 8.05
Lubricating oil full flow filter
Lubricating oil flow ..............see ‘L<strong>is</strong>t of capacities’
Working pressure .........................................4.4 bar
Test pressure .................... according to class rules
Absolute fineness .........................................40 µm*
Working temperature ............. approximately 45 °C
Oil v<strong>is</strong>cosity at working temp. ............. 90 � 00 cSt
Pressure drop with clean filter ....maximum 0.2 bar
Filter to be cleaned
at a pressure drop .......................maximum 0.5 bar
* The absolute fineness corresponds to a nominal
fineness of approximately 25 µm at a retaining
rate of 90%.
The flow capacity must be within a range from
00 to 2% of the capacity stated.
The full�flow filter should be located as close as
possible to the main engine.
If a double filter (duplex) <strong>is</strong> installed, it should
have sufficient capacity to allow the specified full
amount of oil to flow through each side of the filter
at a given working temperature with a pressure
drop across the filter of maximum 0.2 bar (clean
filter).

If a filter with a back�flushing arrangement <strong>is</strong> installed,
the following should be noted:
• The required oil flow, specified in the ‘L<strong>is</strong>t of
capacities’, should be increased by the amount
of oil used for the back�flushing, so that the
lubricating oil pressure at the inlet to the main
engine can be maintained during cleaning.
• If an automatically cleaned filter <strong>is</strong> installed, it
should be noted that in order to activate the
cleaning process, certain makes of filter require
a higher oil pressure at the inlet to the filter than
the pump pressure specified. Therefore, the
pump capacity should be adequate for th<strong>is</strong> purpose,
too.
Flushing of lube oil system
Before starting the engine for the first time, the lubricating
oil system on board has to be cleaned in
accordance with MAN Diesel’s recommendations:
‘Flushing of Main Lubricating Oil System’, which <strong>is</strong>
<strong>available</strong> on request.
