Get cleaner gas, safely, with our exclusive design!

A good bubbler is an essential part of an HHO system. These Heavy-Duty Bubblers are exclusive to HHO-Plus Kits.

Why Do You Need a Bubbler?

Bubblers serve two purposes: cleaning the HHO gas and acting as a safety barrier. When HHO gas is produced from a dry cell, aerosols are produced when the bubbles burst inside the reservoir. These aerosols carry small amounts of electrolyte (potassium hydroxide) which must be prevented from reaching the engine otherwise over time, corrosion could occur. The column of water inside the bubbler scrubs the HHO gas of any electrolyte to give much cleaner HHO gas.  The water in the bubbler will eventually become alkaline from the accumulated aerosols so the water should be changed frequently.  Many people use 1 bubbler unit but we recommend using 2 units in series as an added precaution.

In the event of a flashback, the bubbler acts as a safety barrier. If a flame reaches the bubbler and ignites the HHO that has accumulated at the top, the water column will prevent the HHO from going on to the dry cell because the flame cannot get past the liquid barrier.


Why do you need a non-return valve? 
The Bubbler is placed downstream of the HHO water reservoir which gets warm during use. When the HHO unit is turned off and cools down, the liquid in the reservoir contracts and creates low pressure in the HHO system. Water in the bubbler gets sucked back into the reservoir so the next time you start up the engine, the bubbler could be empty and not serving its purpose. A non-return valve fitted in-between the reservoir and bubbler prevents this from happening and is included.


Technical features

  • Heavy duty high density polyethylene tank with molded side mounting ear. 
  • Thick-walled and heat resistant.
  • Resistant to electrolytes such as potassium hydroxide solution.
  • Tight fitting screw cap with nitrile gasket.
  • Supplied with 2x 3/8" Barbed fittings* and 1 x drain plug in black nylon, 9 mm internal PVC hose.
  • 1 plastic non-return valve is also included.  
*The hose barb fittings are placed inside the container for shipping, but the holes are threaded ready for assembly. The hose barb threads should be wrapped with PTFE tape, as used by plumbers, to form a good seal.

Bubbler Tank measures: 5.5 x13 cm

Stop spending so much money in fuel with HHO System!

Now there is a system that allows you to reduce fuel consumption in your car at a very low cost. Simply use your normal fuel mixed with the hydrogen generated in your own car by a process called electrolysis which splits the water into its components, hydrogen and oxygen.  This mix of hydrogen and oxygen gases are commonly referred to as HHO which is drawn into the engines combustion chamber via the air intake manifold, where they mix with carbon based fuel (petrol, diesel, lpg) and are ignited. Hydrogen diffuses extremely fast and increases the speed of the flame front. It effectively increases the octane level of the air/fuel mixture and allows the fuel to burn almost completely, thus extracting more energy and reducing the amount of pollutants released from the exhaust.  It is important to understand that the hydrogen is not being used as a fuel substitute but as a means to improve the combustion efficiency of your existing fuel so that less is required.

HHO PLUS kits are simple to use and you will be able to install one in your car without the help of a mechanic.

Advantages of HHO PLUS Technology Generators :

1. Savings in fuel expenditure. This is valid for both highway and town (city) driving as well. Just imagine how much you can save by the end of the year!
2. Increases the power and performance of your vehicle. By facilitating more efficient combustion of your fuel
3. Reduces the CO2 emissions. Improved combustion gives improved mpg and results in lower emissions overall.
4. Reduces the temperature in the engine. Also improves engine life-span since its burning at a much cooler state.
5. Removes the carbon in your motor and prevents future carbon build up.
6. Lower noise in the engine. With HHO the engine will sound quieter than before.
7. Increases the life span of your engine.

Safety Warning

The amount of hydrogen produced by on demand HHO kits is small but please note the following:

CAUTION!  Hydrogen is a flammable gas and can form explosive mixtures with oxygen or air. Hydrogen gas poses an immediate fire and explosive hazard when concentrations exceed 4%.  It is much lighter than air and burns with an invisible flame. Before working on an installed HHO system ensure to extinguish all sources of ignition, naked heat including sparks or flames disconnect the vehicles battery terminals and take precautions to eliminate static electricity.  No smoking near the generator or its reservoirs at any time. HHO generators produce HHO gases on demand when the engine is running but when disconnected there will be residual amounts of HHO gases in reservoirs and tubing.  Allow units to vent thoroughly outdoors or in a well ventilated area  before working on the units or accessories.
