The Alfa Laval MAB-104 is a purifier type disc-stack centrifuge. It is designed to separate water (moisture) and fine sediment from mineral oil and lubricating oil. It is primarily used for purifying fuels such as diesel, kerosene, etc. The MAB-104 is also used for separating water and fine sediment from lubrication oil, hydraulic oil, and other mineral oil.
For offshore applications, the centrifuge is configured similar to the OCM-104-Ex configuration with explosion-proof ATEX Zone II.
The MAB 104 centrifuge needs modifications for specific applications such as hazardous area installation, processing of water-based fluids, oil, or fuel. The following is a list of common modifications by Dolphin Centrifuge based on the specific application.
| Centrifuge Modification | Application / Purpose |
| Direct Drive (Replace Friction Clutch) | Explosion Proof Configuration |
| Non-Sparking Friction Blocks | Explosion Proof Configuration |
| Pump Reconfiguration (Capacity) | Lube Oil to Light Fuel OR Light Fuel to Lube Oil |
| Seals Elastomer (Viton / EPDM) | Biodiesel, Hemp Ethanol, Corrosive Chemicals, etc. |
| Gear Pump Replacement | Water Based Fluids (Steel Gear Pump not Suitable) |
| Operating Frequency Conversion | Adapt to Operating Voltage Frequency (50 or 60 Hz) |
| Special Motor Adaptation | Single Phase (110 V or 220 V) Voltage Application |
| Bowl Parts Material Upgrade | Convert Bowl Parts to Stainless Steel (Aqueous Ammonia) |
| Purifier to Clarifier | Convert from 3-Phase to 2-Phase Mode (Clarifier) |
The process oil is fed to the rotating centrifuge bowl from the top (1) and is sped-up in the distributor (2). It then enters the disc stack (3), and it is between the discs that the separation occurs.
The high centrifugal force pushes the water and heavy solids to the bowl wall. The solids accumulate here, and the water travels over the top disc (4) and exits the bowl through the open outlet (5).
The oil (light phase) is moved towards the bowl center and exits the bowl through the open outlet (6).
The centrifuge needs to be periodically stopped for manual removal of separated solids.
The rotating bowl assembly is mounted on a vertical 'bowl-spindle' (7). A horizontally mounted motor rotates the spindle via a worm-gear.
The Alfa Laval WSB 104 Centrifuge is a solid-retaining (aka solid bowl; manual-clean), disc-stack centrifuge ideal for the continuous, three-phase separation of water-based industrial fluids like machining coolant and washer fluid. With a 2 HP Motor, the WSB 104 centrifuge has a bowl RPM of 7,500 and can process 2 GPM of water-based synthetic coolant.
| Model Type | Alfa Laval WSB 104-70 |
| Rated Capacity | 2 GPM on Water Soluble Machining Coolant |
| Sludge Space | 0.25 Gallons |
| Motor HP: | 2 HP |
| Voltages: | 230 / 460 V |

The Alfa Laval WSB-104 is a concentrator version of the MAB-104 disc-stack centrifuge.
It is specifically designed to concentrate oil from water-based industrial fluids such as machine coolant, washer fluid, parts washer solvent, water-soluble cutting oils, de-oiling of split emulsions, etc.
The process fluid is fed to the rotating centrifuge bowl from the top (1) and is sped-up in the distributor (2). It then enters the disc stack (3), and it is between the discs that the separation occurs.
