The demands of emissions regulations have led to higher operating pressures within fuel systems to achieve a more complete combustion process. Higher pressure leads to closer tolerances between moving parts, causing even smaller particles to have more effect on the clearances between these components. The challenge is to remove these smaller particles at the highest efficiency possible.

Our NanoNet filters provide a final stage filtration solution using the same nanofibre media technology that is used in our NanoForce air filters. The nanofibres woven into our media help capture and retain contaminants more efficiently, improving performance by up to 13 times that of standard filters.

Under real world operating conditions, NanoNet has been proven to provide the ultimate protection for high-pressure common rail fuel systems by eliminating wear-causing contamination and maximising the life of the fuel injection components. This substantially improves the reliability of the engine fuel system to reduce downtime and maintenance costs.

With such effective filtration, we can achieve the fuel cleanliness levels dictated by the strict ISO standards of fuel injector manufacturers. It’s easy to see why NanoNet is our leading fuel filtration product.

NanoNet is expanding to cover a larger number of applications and is fast becoming the first choice for filter replacement products within the market.


How does Fleetguard fuel filtration save me money?

Fleetguard fuel products help you achieve the lowest total cost of ownership by meeting or exceeding OE performance requirements. Fleetguard fuel products provide the latest protection technology for your fuel system.

What is the most important factor to know about a fuel filter?

The efficiency to deliver fuel at the cleanliness level specified by the fuel injection system manufacturer (i.e. you need details such as 98.7% efficient at 5 microns).

How will I know I have a fuel issue before I experience fuel system damage/failure?

Indications of fuel problems will be: 1) premature filter plugging which could be evidence of microbial growth in the fuel 2) frequent need to drain water from fuel/water separators which could indicate issues with fuel storage or equipment fuel tanks 3) unusual fuel colour or odour which could indicate improper use of on or off-highway fuel or microbial growth or excessive heat and oxidation resulting in darker fuel colour

For Remote Mount Processors, what does Fleetguard have available?

Fleetguard offers the following fuel processors: Diesel Pro for light commercial applications – flows up to 5.7 litres per minute (90GPH), Fuel Pro for heavy duty applications – flows up to 11.4 litres per minute (180GPH), Sea Pro for medium to high horsepower marine applications – flows up to 68 litres per minute (1080GPH) and Industrial Pro for extreme duty high horsepower mining applications – flows up to 75.7 litres per minute (1200GPH).

What is FIE?

Fuel Injection Equipment represents the entire fuel system including fuel supply plumbing, supply pumps, high pressure pumps, common rail hardware, injectors and return lines.

What is ISO 4406 and what does it measure?

It is the International Organisation for Standardisation measurement methodology for particle counts in fluids at particle sizes >4, >6 and >14 micron-C. The particle counts are typically specified in units of particles per 100 ml of fluid.

What is ISO 12/9/6?

The display of the terminology "ISO 12/9/6" is the proper means of communicating fluid particle contamination as per the ISO 4406 fluid cleanliness methodology. The ISO 12/9/6 is an example of the fuel cleanliness level specified by some FIE manufacturers and corresponds to particle counts per 100 ml of 4000 at >4 micron-C, 500 at >6 micron-C and 64 at >14 micron-C.

What is a micron?

A micron is a thousandth of a millimetre or a millionth of a metre or .000039 of an inch. Micron is the unit of measure used to determinate the size of particles in a fluid which are filtered out by the filter.

What is the difference between Absolute and Nominal micron rating?

Micron rating is the size of particles which are filtered out by filters at a certain efficiency. When this efficiency is at least 98.6%, we speak about absolute micron rating/filtration. Nominal micron rating is just a commercial trick for all efficiencies lower than 98.6%, meaning that for the same micron rating (for example 10 µ) in the case of nominal rating, not all particles will be captured in the filter as in the case of absolute micron rating.

Why doesn't Cummins Filtration publish micron ratings for all its filters?

Generally this is not necessary. Cummins Filtration filters are designed to meet or exceed OEM specifications.
