Figure 4-48 Fuel oil filter arrangement ‘A’
The automatic self-cleaning filter of maximum 10m abs. is used to protect the
engine against serious damage. It captures the catalytic fines which were not re-
moved by the fuel oil separator. In addition, the filter provides a good indication
of the separator's efficiency.
NOTE
The self-cleaning performance must be suitable for the required filter
fineness.
