1.General Information
The M/E LO SYSTEM is one of the most important piping system located in E/R area The
oner and class ha"e a lot of recommendations and re#$irements regarding M/E L$%ricating

FILTER
Next is auto filter, where impurities are collected on filters. Cleaning of filters are done automatically
by using flushing oil from same oil. Clean flushing oil is returned back in to the system from sludge
check filter. In case of maintenance for Auto Filter can be use bypass filter. Auto Filter and bypass
