WB-25 Classic Fuel Cleaning System


12 marine fuel polishing25 litres per minute fuel polishing system, cleaning fuel to 10 micron, removing both free water, bacteria and particulate.

Fuel infection from water or other foreign matter can damage or destroy an engine, so maintaining  fuel quality is vital.

The WB range of Fuel Cleaning Systems offer a fuel cleaning solution with many of the features of the W-PFS range but is the more cost effective solution. These quality systems will clean your fuel automatically, removing water, bacterial infection, sludge solid and semi-solid contaminates from your fuel up to 10 micron. The WB Classic range can be custom built to your specifications and we have a wide range of add-on options to meet all your needs.

Available in either 220v 50hz 1ph AC, 24v DC or 12v DC

If you require touch screen technology, BMS and field bus functionality, emulsified water removal and filtering to 2 micron, we recommend the W-PFS Range.

*Please note, the dimensions, weights above are for the wall mounted version. The enclosure revision will be slightly larger and heavier. 

**Flow rates quoted assume the ideal conditions, a large positive head, no left, wide pipe work, etc. Narrow pipes, tight bends, elbows, lifts and other such external factors can and will impact on the maximum flow achieved by the system.


The WB range of products is typically wall mountable and should be installed close to the fuel tank it is cleaning.

In any typical fuel tank, the pipe feeding fuel to the engine is not at the bottom, however to successfully clean fuel, the pickup pipe going to the WB unit should be right at the bottom of the tank, below the engine feed.

The return pipe from the WB unit should ideally be at the top of the tank at the opposite end to the pick up; if this is not possible the top of the tank at the same end is acceptable.

Apart from that, the list below highlights our recommendations.

  • A fused spur is required to power the system (24v DC or 220v 50hz 1ph AC).
  • Only two pipes are required (input/pickup and output/return)
  • We recommend a non return valve on the input pipe
  • Alternatively we recommend a foot valve at the tank end of the input pipe
  • We recommend isolating ball valves before and after the system
