About the Alfa Laval MMB Series

On a superyacht, space is limited, operations are demanding, and expectations are high. The MMB 304 and 305 modules are compact, self-contained systems designed for effortless integration into engine rooms or auxiliary machinery spaces. These units continuously remove harmful water and solid contaminants from marine diesel or lube oil, ensuring cleaner combustion and reduced engine wear, critical for long-range cruising or charter operations where reliability is non-negotiable.

MMB 304 vs MMB 305

Choosing the Right Fit

Both the MMB 304 and MMB 305 share a reliable, proven design known for performance, durability, and easy maintenance. The main difference lies in flow capacity.

Designed for vessels with moderate fuel demands, the MMB 304 offers robust filtration and separation performance suitable for smaller to mid-sized yachts. It delivers consistent results for engines and generators that operate within standard fuel flow ranges.

Engineered for higher throughput, the MMB 305 supports increased flow rates, making it the preferred choice for larger yachts or installations with more powerful engines and multiple onboard generators. This model is ideal where continuous, heavy-duty operation is required.

Applications Usage

Superyacht Edition

These Alfa Laval modules are especially well-suited for:

  • Continuous purification of marine gas oil (MGO)
  • Lubrication oil treatment for propulsion engines and generators
  • Onboard fuel polishing systems
  • Pre-treatment for bunkered fuel to meet engine warranties and IMO compliance

Whether your yacht is preparing for a transatlantic voyage or maintaining peak condition for charter service, MMB modules offer the peace of mind that your oil systems are clean, efficient, and reliable.
