The FBO assembly is used as a primary fuel filter/water separator on large diesel applications, as well as on mobile refuelers and fleet re-fueling pumps.
In engine applications, it is specifically designed as a primary fuel filter/water separator for today's high pressure common rail diesel injection systems.
The FBO assembly can flow from 5 gpm to 75 gpm, depending on the model, element, and type/viscosity of fuel to be filtered.
The large 5.1 oz sump is ideal for applications experiencing high volumes of water in the fuel.
Common applications include diesel locomotives, mining trucks, mobile refuelers, fuel dispensing pumps, fuel docks, etc.
These Marine versions of the FBO filter housing are designed for use on boats. The Marine FBO is UL listed, meets Coast Guard and ABS requirements, and undoubtedly offers benefits for insurance purposes.
Compared to the Industrial (black) version of the FBO the Marine version is white, UL listed, and features, as standard, a differential pressure gauge (indicates time to change the element), a sight glass to check water level, and a mounting bracket.
Three element options are available to meet various requirements:
1) Fuel filter/water separators (coalescers) are the most commonly used elements - especially for single filter installations - as they both filter particles and contaminants and also separate water from the fuel.
Today's sophisticated diesels are particularly susceptible to damage from water and particulates, so ultra-fine 1 and 5 micron elements are commonly used for this function.
2) Silicone-treated particulate pre-filters (also called microfilters) are most often used as primary filters to extend the life of other filters further downstream.
3) Water absorber elements also filter particulates and have micron ratings. They tend to be specialty items and are most commonly used on farm and fleet fuel dispensing pumps.
