Table 1: Fuel oil filter duplex
To safeguard the injection system components on
the GenSets, is it recommended to install a fuel oil
filter duplex, as close as possible to each GenSet.
The fuel oil filter duplex is with star-pleated filter ele-
ments. The fuel oil filter duplex is supplied loose and
it is recommended to install it, as close as possible
to each GenSet, in the external fuel oil supply line.
GenSets with conventional fuel injection system or
common rail fuel system must have fuel oil filter
duplex with a fineness of max. 25 microns (sphere
passing mesh) installed as close as possible to
each GenSet.
The filter surface load of the 25 microns filters must
not exceed 1.5 l/cm² per hour ! Figure 1: Fuel oil filter duplex.
