Alfa Laval MIB 303
The MIB 303 is Alfa Laval's compact, entry-level separator for smaller vessels and coastal craft, built around a straightforward manual-cleaning design rather than automation. Its solid bowl opens without special tools — loosen the hood bolts and the disc stack stays in place — making routine servicing something a crew can handle themselves. It's suited to purifying distillate fuels and lower-temperature lubricating oils, and its small footprint lets it fit into engine room corners larger separators can't reach.
