NanoEFX for military, emergency & public-sector fleets
NanoEFX is a passive, water-based air-filter treatment that helps public-sector engines burn fuel more completely — supporting lower fuel consumption and lower emissions across municipal fleets, fire and emergency vehicles and standby gensets, with no engine modification and no downtime.

A coating on the air filter — not a fuel additive or a remap
NanoEFX is sprayed onto the engine's existing air filter, where it dries into a thin, breathable nano-coating. As the engine draws air through that treated surface, the coating conditions the intake air before combustion — supporting a cleaner, more complete and more efficient burn. For a public-sector fleet, that means the same treatment works across every engine that breathes through a treatable filter.
What it is
- A passive nanostructured intake-air treatment
- Applied to the air filter you already service
- 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 public operator already feels
These are the forces that make intake-air efficiency worth acting on — independent of any single engine or duty cycle.
Public budgets and fuel cost
Fuel is a large, controllable cost across a public fleet, and every litre saved frees public money. Because the effect repeats across every vehicle and every route, savings accumulate across the fleet.
Clean-air and net-zero commitments
Cities and public authorities set air-quality and net-zero targets and are accountable for meeting them. A more complete burn means less CO, unburned hydrocarbons and soot in the areas they serve.
Reliability of emergency and standby power
Emergency vehicles and standby gensets must be dependable. A cleaner burn forms fewer new deposits, easing maintenance of assets that have to start and run when needed.

Our own trials in this duty cycle
Municipal fleets give us our best-documented trial and our only one with a control group. Both are here, with their limits attached.
What this duty cycle actually consumes
A refuse collection vehicle in our Waste Services trial consumed 23.9 l/100 km across the fleet before treatment; Japanese service buses in our records run at 2.5 to 2.9 km/L. Municipal duty is stop-start, high-load and repetitive — which is what makes week-to-week fuel data unusually comparable.

From a municipal refuse truck to a standby genset
A public fleet is rarely one vehicle type. NanoEFX applies to any internal-combustion engine that breathes through a treatable filter, and it conditions the intake air regardless of the fuel burned.
Equipment types
Fuels
No workshop, no downtime, no new hardware
NanoEFX is applied by your own team, onto the air filter they already remove at service. It rides on the maintenance you do anyway rather than adding a new one.
What a cleaner burn means for a public-sector fleet
NanoEFX doesn't add energy or oxygen and doesn't modify your engine — it helps the engine waste less of the energy already in the fuel. NOx response is engine- and control-system dependent.
Common questions from operators
Does NanoEFX work across a mixed public and emergency fleet?
Will it change the engine or need an ECU remap?
How often does it need reapplying?
Does it help meet clean-air commitments?
Does it affect a DPF, SCR, EGR or AdBlue system?
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.
