What Is a Dual-Fuel Generator, and Who Is It For? Natura
A dual-fuel (or gas-gasoline hybrid) generator has a standard gasoline tank and a connection for a propane tank. You use a lever to choose which fuel to use; in Natura, plus, you can shift gears without turning off the engine.
Natura It's for three types of people: those who have gas cylinder at home or on the property and wants to spend less; anyone who has a generator "just in case" and doesn't want to find that it's filled with old gasoline on the day they need it (propane doesn't degrade); and those who already have gas on board —food truck, RV, fair booth— and runs on a single fuel. Three models with electric start, Euro V engine, copper alternator, and regulation SVR that can handle the startup surges from the refrigerator and the pump.
- 3,300–8,500 W, twomodels, single-phase

How Fuel Switching Works
The patented selector lever SDS Tech makes using gas just as easy as using gasoline.
What do you need it for?
The generator that sits idle for months
Gasoline degrades in the tank within a few months, and on the day it runs out, the engine doesn't start right. Propane can be stored for years without losing its properties: you connect the tank, and it starts right up. Natura 6000 for almost the entire house.
You already have a gas tank: skip the gas station
Whether it's a country house, a farmhouse, or a home with a propane supply: the same gas you use for cooking or heating powers the generator. Natura 6000 or Natura 8000 depending on the home.
If you turn it on every week, the gas bill pays for itself
Irrigation, workshops, off-grid businesses: With propane, you save up to 40% compared to gasoline and 25% compared to diesel. The more hours you use it, the more you save. Natura 8000.
You already have gas on board
The stove and oven run on a propane tank—and so does the generator. A single fuel source means less gasoline odor near the food and less smoke. Natura 6000 for refrigerators, coffee makers, lighting, and POS terminals.
The RV's propane tank also provides light
If you're traveling with propane, Natura 3500 It uses the same gas cylinder. Watch out for the noise, because it's not an inverter model: if you're camping near neighbors, check out the silent inverters.
Where you don't want gas cans
Community garages, commercial spaces, boat docks: a sealed gas cylinder can be stored more safely, without leaks or vapors. Natura 3500 or Natura 6000.
Terraces, gardens, urban projects
Propane emits less carbon monoxide and hydrocarbons than gasoline: less smoke and less odor around people. Always use it outdoors, just like any other generator.
Why Natura
Two fuels, zero dependence
Gasoline from any gas pump or propane from any tank. Whatever you have on hand. And if one runs out, the other keeps going.
Change in progress (SDS Tech)
Patented lever for switching from gas to gasoline without turning off the engine, with the generator unloaded. Other dual-fuel systems require you to stop, bleed the system, and restart.
Propane does not expire
It can be stored indefinitely without deteriorating, doesn't spill, and doesn't give off fumes in the garage. The ultimate selling point for an emergency generator.
Up to 40% savings
Compared to gasoline, and 25% compared to diesel, based on average prices in Spain. It also produces fewer CO and hydrocarbon emissions.
Long battery life
20- to 28-liter gas tank: up to 23 hours at 25% load in Natura 3500. With a 12.5-kg tank, about 19 hours. And you can use both fuels in succession.
Mechanics Genergy
Euro V engine, 100% copper alternator, regulation SVR (a 3,300 W unit can handle peaks of 4,200 W), battery-powered electric start, display showing operating hours and maintenance alerts, and automatic shut-off due to low oil level.
Which of the three Natura?
The engine performs slightly worse on gas than on gasoline: when choosing a model, check the power rating for propane if you'll be using mostly propane tanks.
| Model | Gasoline Power | Propane Power | Deposit | Gasoline Range (25%) | Range with a 12.5 kg cylinder | Who is it for? | From |
|---|---|---|---|---|---|---|---|
| Natura 3500 | 3.300 W | ~3.000 W | 20 L | ~23 h | ~19 h | The Essentials for a Home, RV, and Secure Storage | starting at — € |
| Natura 6000 | 5.500 W | ~5.000 W | 28 L | ~— h | ~— h | House almost finished, food truck, emergency supplies stocked | starting at — € |
| Natura 8000 | 8.500 W | ~7.700 W | 28 L | ~— h | ~— h | Large home, frequent use, business | starting at — € |
Gasoline power ratings are based on the specifications for each model on this website; propane power ratings are approximate (about 10% lower). The ranges of Natura 6000 and Natura 8000 and the prices are pending confirmation in the official 2026 catalog.
How much does it really save?
It depends on the daily price of gas and propane in your area, so the fairest thing to do is to give you a way to calculate it:
Based on average prices in Spain, running on propane is about 40% cheaper than running on gasoline and 25% cheaper than running on diesel. The more hours per year you use it, the sooner you’ll see the difference: whether for irrigation, in a workshop, or for business, a few hundred hours a year translate that difference into savings equivalent to several propane tanks. The hourly consumption for each model is listed in its technical specifications; multiply that by the price you pay and compare.

Gas, gasoline, or diesel generator?
| Criterion | Gas (propane or butane) — Natura | Gasoline | Diesel |
|---|---|---|---|
| Cost per hour | The lowest (up to 40% less than gasoline) | Medium | Low-to-medium |
| Fuel Storage | Undefined, no spills or vapors | It breaks down within months | Months; it can lead to bacteria and water |
| Availability | Gas cylinders available at any gas station or via home delivery | Any fountain | Any fountain |
| Emissions and Odor | Less CO and hydrocarbons, no gasoline smell | More | More particles |
| Power | About 10% less than with gasoline, with the same engine | The nominal | Great Powers |
| Extreme cold | Propane is fine; butane is a bad choice below 0 °C | No problem | It can gel |
| Choose… | Emergency storage, propane tank at home, frequent use, less odor | Simplicity and purchase price — see gasoline | Continuous and industrial use — see generator sets |
Natura It's the best of both worlds: gas when you want to save money or stock up, and propane when you run out of propane.
Will the butane tank we have at home work?
This is the most common question, and the answer is yes—with one caveat.
Propane (11- and 35-kg cylinders)
The reference fuel for Natura. It sprays well even at sub-zero temperatures: the ideal choice for outdoor use, winter, and frequent use.
Butane (12.5 kg household gas cylinder)
It works because both are LPG, but butane doesn't vaporize well in cold weather: below 0 to 5 °C, the cylinder may not provide sufficient flow even when fully charged. It's perfect for summer and temperate climates; for winter outdoor use, use propane.
The regulator
The generator has a regulator built into the chassis. The gas cylinder requires its own regulator, rated at 30 mbar and with sufficient flow rate (2 kg/h or more): this is the standard for Spanish gas cylinders, but check yours before connecting it.
Large gas cylinders or tanks
For frequent use, a 35-kg cylinder or the home's propane tank will extend the operating time by several days. Contact us for installation.
¿Natura, Cube Or a small hybrid inverter?
| Criterion | Natura | Cube | Gas/gasoline hybrid inverters from other brands |
|---|---|---|---|
| Fuel | Gasoline or gas, with gear changes while driving | Gasoline | Gasoline or gas |
| Power | 3.300 – 8.500 W | 2.800 – 7.000 W | Typically 2,000–3,000 W |
| Noise | Conventional (67–72 dB) | Conventional (67–72 dB) | Inverter, quieter |
| Automatic Start | No | ATS and SOL | According to the brand |
| Warranty and Technical Support | 3 Years and SAT in Spain | 3 Years and SAT in Spain | She often shops online from another country |
| Choose… | If you want gas: savings, storage, and an on-board tank | If you want it to start on its own — see Cube | If you need less than 3 kW and quiet operation: Natura That's not your line; check out our inverter |
We say it even when we don't mean it: Natura It is not an inverter and does not have an automatic start feature. For automatic backup, Cube ATS; for silence, Inverter Silent.
