NanoEFX for agriculture
NanoEFX is a passive, water-based air-filter treatment for combustion engines with a treatable intake filter or intake medium. It can be applied to tractors, harvesters and other farm machinery where such a filter or medium is present. We have not yet run an agricultural trial, however, so we do not assign a sector-specific fuel-saving percentage to tractors, harvesters or other farm machinery.

|---|---|
| Applies to | Tractors · Combine & forage harvesters · Sprayers · Irrigation pumps · Forestry machines |

A coating on the air filter — not a fuel additive or a remap
NanoEFX is sprayed onto the engine's air filter — the existing one, or a replacement filter treated in advance — where it dries into a thin, breathable nano-coating. As the engine draws air through that treated surface, the coating is designed to condition the intake air before combustion, with the aim of supporting a cleaner, more complete burn — what we have measured is set out below. For a farm fleet, that means the same treatment can be applied to every engine that breathes through a treatable filter — whether it lowers fuel use on a given engine is what a pilot measures.
What it is
- A passive nanostructured intake-air treatment
- Applied to the engine’s air filter
- Water-based — dries to a thin, breathable coating
- Works before combustion, at the intake-air stage
What it isn't
- A fuel additive or oil additive
- An ECU remap or tuning
- A mechanical retrofit or powered device
- Anything that changes how you operate
Three pressures every farm operator already feels
These are the forces that make intake-air efficiency worth acting on — independent of any single engine or duty cycle.
Fuel is a major input cost
Field operations are fuel-intensive, and fuel is a large, controllable cost on the farm. If a pilot measures a gain that holds over a representative period, even a modest one could add up across a season; whether it carries over to other machines is checked separately.
Sustainability in food supply chains
Buyers and farm-assurance schemes increasingly ask for lower-carbon production. A more complete burn is the aim — less fuel wasted per hour of field work; measured results vary by machine and duty cycle.
Non-road emission standards
Farm engines fall under non-road emission standards such as EU Stage V. Combustion theory would expect less CO and unburned hydrocarbons from a more complete burn; we hold one accredited measurement on one vehicle, so treat it as a possible contribution within a tightening framework, not a compliance measure.

No trial data from this sector
Why this sector matters — independent figures
EU agriculture and forestry consumed 26.4 million tonnes of oil equivalent in 2023, 3.0% of total EU energy consumption — and oil and petroleum products still supplied 58.3% of the sector’s direct energy.

We have no agricultural trial data. No tractor, harvester or irrigation pump appears anywhere in our records.
The nearest evidence we hold
Nothing in our evidence transfers cleanly. The nearest duty cycle we have measured is heavy road haulage: four diesel vehicles at Inabe Logistics Service in 2016 — two 10 tonne tippers and two trucks — improved by 4.9% to 7.1% in fuel efficiency measured in km/L, a median of 6.3%. Those are road vehicles. A tractor under sustained PTO load is a different machine doing a different job, and we will not present that figure as an indication for farm equipment.
What a trial here would have to look like
Field work is seasonal and highly variable, so a credible agricultural trial needs either a full year-on-year comparison of the same operation, or treated and untreated machines working the same task in parallel with hours and area logged. We would rather run one properly than quote a number from elsewhere.

From the main tractor to the irrigation pump
A farm is rarely one machine. NanoEFX can be applied to agricultural engines that breathe through a treatable air filter, and it works at the intake air, whatever the fuel burned.
Equipment types
Fuels
For the fuels marked above we have no documented field validation, so we make no performance claim for them.
No workshop, no retrofit, no new hardware
Your own team either fits a pre-treated filter, or treats the existing filter, lets it dry for at least 20 minutes and refits it.
What this could mean for a farm fleet
NanoEFX doesn't add energy or oxygen and doesn't modify your engine — it is designed to help the engine waste less of the energy already in the fuel. NOx response is engine- and control-system dependent.
Common questions from operators
Can NanoEFX be used on our tractors and farm diesel engines — and what can we expect?
Does NanoEFX make any change to the engines of our farm machinery?
How often does NanoEFX need reapplying over a season?
Can NanoEFX help lower the carbon footprint of our production?
Don't take the claim — measure it
The most honest evidence is your own baseline. In a NanoEFX pilot you run a controlled trial on your own engines, measured against your own fuel data — and you only pay if it proves savings.
