Alfa Laval Moatti L280

Manual lube oil filter para sa diesel engine

Alfa Laval Moatti L280 is a manual (non-backflushing) lube oil filter for diesel engines, used either as a by-pass filter or as an indicator filter after an automatic filter. Oil enters the inlet body, passes the filter insert and leaves through the outlet body; a differential pressure indicator with an electrical contact warns the engine control system when the insert clogs. The book covers safety, function, operation checks, troubleshooting, the yearly overhaul with tools and spares, installation and parts lists.
