Alfa Laval MIB 503
The MIB 503 scales up the same compact, manual-cleaning design to handle higher fuel flow rates and significantly higher lube oil temperatures, up to 95°C. It's typically supplied as a complete skid-mounted module and can be paired with Alfa Laval's MIBMatic control unit for automated operation and remote monitoring — capabilities the smaller 303 doesn't offer.
