Fuel oil filter — Arrangement ‘B’
A maximum 10 m abs. filter of automatic self-cleaning type is installed in the
'hot' booster system close to engine inlet. The filter needs to be laid out for a max-
imum working temperature of 150 °C.
Same filter specification as provided by Table 4-12,  4-77.
Figure 4-49 Fuel oil filter arrangement ‘B’
Arrangement ‘B’ does not include secondary duplex filtration. It lacks the indi-
cation of overall performance of the fuel oil treatment system and gives no indi-
cation when the automatic self-cleaning filter fails.
NOTE
The self-cleaning performance must be suitable for the required filter
fineness.
NOTE
WinGD recommends Arrangement ‘A’, as this is a best practice solu-
tion.
