HHO Hydrogen On Demand System for 4 and 6 cylinder engines.
Application: Compact to midsize cars with 1 to 5 liter engines.
Recommended to be installed on mid-size vehicles up to full-size trucks

There are two ways you can buy this system.

The basic system shown here comes with everything needed to do a basic install.

A "basic system" is for customers that all ready have the required electronics to make a HHO system work properly.

And the full system shown here that comes with everything to do a full system install
including all required electronics. Volo FS-2 HHO chip and PWM controller.

When purchasing a "FULL" system please indicate your vehicle year, make and model so we can program your Volo FS2 HHO chip. The Volo chip will work with 1996 and newer vehicles. If your vehicle is older please contact us. We have a solution for your vehicle.

With the ever increasing costs of fossil fuels and planned shortages by the international oil producers, The Hydro GFx1 fuel cell is an essential fuel assistant for the internal combustion engine application in the Automotive Fuel Arena. If you are looking to save from 20 - 40+% on your fuel costs and get back that new car performance and if you want to extend the oil change and tune up time service period and ultimately lower your exhaust emissions to exceptional levels, then a Hydro GFx1 on demand hydrogen fuel system is easy to install and pays for its self in a matter of a few months.
Reactor is only 6" round x 2 3/4" thick.
Produces enough HHO to enhance up to 5.0 liter engine.

This new unit uses a simple mix 10 teaspoon KOH in 2 liters of distilled water.
The cell is made up of 20 specialty designed and spaced
plates of stainless steel and high temp HDPE wall.
The unit comes in a complete add on kit!

Takes about 2 to 4 Hour to install
Will Work On fuel injected, carbureted or Diesel up to 5.0 liter engines. Average Mileage gains will be between 20 to 40% and a noticeable increase in power!
What is happening is you are introducing Hydrogen and Oxygen in to the air stream of your vehicle. The Hydrogen and Oxygen not only is adding supplement fuel to your engine, making it a HYBRID, but the extra oxygen is helping your normal fuel burn more complete raising power, better mileage and lower emissions.
You can see savings of double the cost or more in first year of use!
So add a HHO generator to your vehicle and see and feel the difference!
Not guaranteed to fit your vehicle. Please measure for size under your hood before buying.
Custom sizes are available. Simply tell us the size and space you have and a unit will be built to fit your vehicle.


If your vehicle is fuel injected and you install a hydrogen generator, your mileage will decrease unless you install some type of fuel leaning device. THIS IS TRUE FOR ALL HYDROGEN GENERATORS (except when installed in a carbureted or diesel vehicle) that is why we have included the
Volo chip in the full system. The reason fuel mileage will decrease as stated above, is because the oxygen sensor will detect a larger amount of oxygen in the exhaust and think the engine is running lean. Because of this, the oxygen sensor will tell the engine's computer to increase the fuel going to the engine. The Volo chip is used to lean your engines fuel so your vehicle will receive the full benefits of the GFx1.

What is a Volo fs2 HHO chip?

This chip has been specifically tuned for the needs of HHO generator equipped vehicles. The FS2 is dynamic - which means the FS2 will consider oxygen levels in the exhaust, along with engine speed and load, intake air temperature and volume, and many other variables to determine the most efficient fuel delivery rate and timing at up to 256 separate load points.
When using HHO as a fuel supplement, the FS2 will adjust fuel delivery and timing to optimize efficiency.
When HHO is disabled, the FS2 will automatically re-adjust and switch to highly efficient, non-HHO enhanced maps.
The FS2 is a vehicle specific, custom programmed 20MHz Microcontroller. It utilizes its high speed serial input/output to communicate directly with the ECU through the OBD-II port.

What is a PWM Controller?

A PWM is a electronic device used to control the amount of power that goes into the HHO cell. The amount of power determines how much HHO will be produced by the cell. It also keeps the cell at the desired amount of power. Keeping the cell running cool and the whole system within desired specifications. Any company claiming their system doesn't need a PWM either doesn't know what they are doing or is deceiving you.
