What is SFD Diesel purifier?
The SFD Purifier is, by definition of the Society of Automotive Engineers (SAE), a combination Primary Fuel Filter and Fuel / Water Separator and temperature controller on permanent basis. It removes up to 90 percent of solid contaminants (down to approximately 12 microns) and 99.8 percent visible water, including emulsified water that may be in the fuel. The SFD Purifier, depending upon the model, typically has six to ten times the contaminant storage capacity of other combination primary fuel filter / water separator products on the market. The oversize storage reservoir capacity is particularly important when you do get an occasional load of contaminated fuel.

How does the SFD DIESEL PURIFIER work?
Unlike most other type combination Primary Fuel Filter, Fuel / Water Separator products, the SFD Purifier product is not a spin - on type canister or a replaceable cartridge type unit. In contrast, the only moving item inside the SFD is the fuel itself. The SFD product works on a simple centrifugal principle that swirls the fuel from the top to the bottom of the unit, where solid contaminants and water stay until drained, then the Diesel will go through simple process of filtration . No canisters or messy cartridges to replace, no screens requiring cleaning or replacement. There are no internal parts that will ever require replacement. Fuel Purifier also extends the life of the fuel filtration system provided by the engine manufacturer by removing sediments algae, oxides, dirt, dust and prevents the formation of harmful sulfuric acid in the fuel.

"This isn't important, I don't have fuel problems."
Don't kid yourself. Water is continually being formed in all fuel storage tanks from condensation. This process goes on day and night. If the tank is steel, this also sets up the possibility of rust contamination. As processed fuel is transferred in the marketing system, it can pass through as many as eight or ten different tanks before it finally reaches your vehicle. In some of these transfers, it may be filtered in some manner, often it is not filtered. Once it reaches its final destination, your vehicle tank, what are you getting? And don't forget, condensation is still forming water in your tank!

"New Engines today have good filtration systems."
True. They also demand ONLY the Highest Quality Fuel entering the cylinders. Fuel pressures today are extremely high. For example, Bosch mechanical type fuel pumps have pressures set as high as 17,000 PSI. HEUI type Unit Injector Systems used by Caterpillar, Detroit Diesel and Navistar in their electronically controlled engines have fuel pressures as high as 28,000 PSI. As the fuel is transferred from the tank to the engine, you have but a single opportunity to catch and hold any and all contaminants. With these types of pressures, the smallest particle of water or solid contaminant can do a lot of very expensive damage in a millisecond. A lot more than the cost of an SFD Purifier!!!

Advantages of the SFD Purifier!
There are many advantages and benefits to the owner and operator with the installation of an SFD Pirifier. These advantages include the following:
