AquaCure Model AC50 (used/refurbished)


The AquaCure Model EA-H160 has been REPLACED by the model AC50
Buy the new AquaCure Model AC50 HERE:

The AquaCure® (Model AC50) is our MOST ADVANCED and user-friendly HydrOxy for Health machine.  It has several features that our customers were asking for.  Like easily-adjustable gas volume and an hour meter.  We also added a Tower Cap which makes the AquaCure simpler to use and even more reliable.

The AquaCure Model EA-H160 is no longer available on this sales page… We now only sell the refurbished AquaCure Model AC50 and only when they are available (they get snapped up fast).

Of course we still (and will continue to) support the AquaCure Model EA-H160, as we support ALL our products going all the way back to 1984.

SKU: Refurb AquaCure Category:


The AquaCure (Model AC50) can generate up to 50 liters per hour (lph) of mixed hydrogen and oxygen gases.

This mixture of gasses has MANY trade names.
For the purpose of AquaCure we’ll call this gaseous mixture HydrOxy.

The AquaCure is LOADED with SAFETY features (see below).

The AquaCure is a practical, reliable and versatile HydrOxy electrolyzer (generator) that should give you years of trouble free service.

The AquaCure can be used continuously with minimal maintenance
(just add pure water as needed and clean it at least once a month).

For LEGAL REASONS we need to state up front that the AquaCure is NOT yet defined as a MEDICAL DEVICE and therefor cannot legally be recommended for human use.
Legal uses would be for plants, fish, birds and mammals.

Hundreds of scientific studies have proven that it is safe for plants and animals to use for drinking and breathing.  Current studies are proving that humans are having all the same benefits proven on Plants and Animals but until we get medical certification we cannot (for legal reasons) recommend it for human use.
Note: A study of all the studies (including on humans) shows NO negative side effects of hydrogen, only positive benefits.  See our full Medical Disclaimer here:

The AquaCure is 110-125 VAC 60 Hz (North American standard)

IF you want a version compatible with 220-240 VAC 50 Hz,
We are now stock the ‘international version’ but this sales page doesn’t yet have that ‘feature’ as an option, so just state that you want the international version in your order comments so the mail room will get the correct version to you.

Note that the 220-240 VAC version has a mechanical timer switch instead of an electronic one because that’s the ONLY version of timer we can acquire in North America that is compatible with 220-240 VAC.  the newest version does have the ‘continous’ option.  It will work fine, as is, but you can trade it out for a local timer switch (if you wish) once you receive your AquaCure.

AquaCure comes with access privileges to an online AquaCure Resources, which will give you instruction videos, tips, options and (quite frankly) anything we can think of to enhance your user experience.  The online Resources ae updated as needed to assure that you will always have access to the most recent information.

Warranty includes parts, labor and shipping if issue is manufacturer related.  We’ve been in business since 1984 and expect to be in business at least another 20 years.

If Warranty is invalid (because of user or shipping abuse), we will still repair any issues for lifetime if purchaser pays for parts, labor and shipping.

100% satisfaction Guarantee

SATISFACTION GUARANTEE: We can’t guarantee any particular result because every body is different.
HOWEVER, because we are SO CERTAIN you’ll be happy with this machine, we have a 100% no questions asked one YEAR money back satisfaction guarantee(from the date you receive the machine).
You don’t need to state a reason if you want to return the machine (even after used for 12 months), just ask for an RMA number and instructions to properly send it back and (once we receive the machine) we’ll refund your purchase price (shipping, taxes and duty costs not refunded).

We reserve the right to discount the refund to cover any customer related damage
(normal wear and tear is expected and will not be discounted).
Adequately package and insure when shipping to cover potential shipping damage.

Resources, Warranty and Guarantee are privileges we extend to customers that purchase directly from us.  Distributors, other manufacvturers, etc. will have their own customer services.

AquaCure has a low water level switch to automatically shut off the machine if the liquid level gets low.

Running ANY electrolyzer out of water can cause internal explosions that could lead to damage and harm.  Most electrolyzer manufacturers don’t mention this issue because they do NOT have low liquid level shutoff.
They depend on you to visually check the liquid level frequently.

AquaCure shuts off the gas production when liquid level gets low, so no danger condition can exist.  AquaCure also has a low level alarm and indicator light, so there is no question when the liquid is low.

Low level control also allows the AquaCure to be used as an oxygen source for Mammals needing additional oxygen…
… with the additional benefit of getting hydrogen (something an oxygen concentrator or bottled oxygen can’t do).

Liquid level control is REQUIRED in applications where the electrolyzer is going to operate unattended for long periods of time; for examples:

  1. When needing extra oxygen all night (also gives hydrogen and ExW).
  2. Using HydrOxy to continuously bubble water for hydroponics / aquaponics.
  3. Automatically feeding HydrOxy to a furnace for combustion enhancement.
  4. Creating ‘NEW WATER’.  New Water is water that’s had its memory entirely erased and the things that you can do with it (like programming for health and transmutation) are astounding!

We’ve added a ‘reserve’ tank to the machine, so it can operate for hours longer between ‘refills’.  This is needed when using the AquaCure for applications requiring continuous use.

The AquaCure has an ‘anti-backfill’ feature, that reliably prevents the water in the filter, humidifier and bubblers from ‘back-feeding’ (getting sucked back) into the electrolyzer upon shutdown.
Many electrolyzers do not have this feature and/or the ‘feature’ isn’t reliable.

Backfill isn’t ordinarily a ‘big problem’ in itself…
EXCEPT if there is a backfire (from the machine or from static electricity).

The PRIMARY backfire suppression is the stainless steel ‘filter’ tank, but it must be full to do ALL its job(s) properly.  The jobs of the primary filter are:

  1. To pre-filter out any residue of lye (NaOH) that comes out of the machine with the gas.  If there is not enough liquid or if it isn’t changed often enough, this function becomes compromised.
  2. To stop backfires originating in the machine or from the output gas.  If there isn’t enough liquid in the filter, this function becomes compromised.
  3. If HydrOxy is being used to fuel a torch, the filter water can be replaced with a ‘buffer’ like alcohol (of various kinds) to ‘cool’ the flame and/or make the flame less oxidizing for specific applications (buffer fluid is seldom needed but IS an option).
    But again, the liquid level (buffer) must still be high enough to clean the gas and stop a backfire AND, (here’s where, if there is backfilling from the filter it becomes a bigger issue) the electrolyzer’s electrolyte would actually become contaminated with the alcohol and would need to be changed immediately (very inconvenient).
  4. So a reliable anti-backfill feature is IMPORTANT!

AquaCure Gas Volume is sufficient (~ 50 LPH) to ‘charge’ water quickly and supports the 4 treatment protocols (plus the potential of NEW water).

1. Bubble (infuse the water with HydrOxy) for healthful drinking and for feeding to plants and animals.  Can also be used to enhance hydroponics, aquaponics, fish growth, etc.

2. Bubble (infuse the water with HydrOxy) for topical treatment of skin issues and wounds,

3. Bag HydrOxy gas for external treatment of skin, wounds and various pain relief (like arthritis and carpel tunnel).

4. Direct BREATHING (inhalation) of HydrOxy gas (hydrogen / oxygen mixture), to efficiently put the hydrogen directly into the blood for fast, efficient whole body hydration.

SAFETY NOTE:  While breathing some hydrogen has been proven beneficial in hundreds of scientific studies, do NOT want to breathe TOO MUCH hydrogen volume (> 4% in air), because higher concentrations of hydrogen are potentially explosive and you do NOT want an explosive mixture of anything in the lungs!
The AquaCure is designed to keep the volume of hydrogen inhaled below the combustible limit in a 120 lb to 175 lb Mammal (you’d want to reduce the gas volume for smaller mammals).

5. There are ‘developing application’ protocols that use ‘NEW WATER’ that is generated by collecting the condensation of the HydrOxy flame.  The AquaCure is designed to ‘make’ New Water (using the correct attachments).

AquaCure has a timer switch, for convenience and efficiency.  Treatments can be easily timed so no gas is produced beyond timing needed.
The timer switch also has a ‘continuous’ setting, so that HydrOxy can be produced for extended times (until the low level switch shuts it off).

This switch completely shuts off power to the AquaCure.  Most other electrolyzers only shut off the ‘power’ wire (like the timer switch would), leaving the neutral wire connected to the Grid.  For safety, we shut off BOTH the power and neutral wires.

ATTACHMENTS that normally come with the machine (see above picture).

1.  2 of Nasal Cannula for Inhalation; (also used for bubbling tube and/or torch hose).

2. 1 of humidifier (to scrub HydrOxy of any possible lye mist) + attachment hose

3. 1 of Soft Silicone HydrOxy Spot Applicator (with hose adaptor)

4. Basic Operation Manual (updates, upgrades, additional information in the Resources).

5. Medium Bubbler
So you can infuse your drinking water AT THE SAME TIME as breathing the gas.

6. Additional bubbling stone,
so that you can bubble the HydrOxy into other containers of water.

OPTIONAL ATTACHMENTS (you can order in addition to the above)
to order these additional options, go to the bottom of the AquaCure Model AC50 Sales page and put them in your shopping cart.

Some of the items below are already included with the AquaCure, but are listed in case you want extras.  You can purchase most of them on our ‘Parts’ page.

1. Humidifier Holder:  $15
Bracket that can be appropriately attached to the machine (if needed) to help with portability (holds humidifier so it doesn’t need to be detached when the machine is moved).

2. Extra nasal Cannula(s) (for Inhalation): $5
Good to have extras for more people to use, and you’ll want to trade them out occasionally as they get ‘snotty’.  You can clean them for awhile using alcohol or bleach solution (I prefer colloidal silver to wash and disinfect the cannulas).
Note: Used cannula hoses are still useful (cut off the cannula) for spot applicator and torch fuel-gas hoses.

3. 20 foot Cannula Extension hose, which allows people to walk around while breathing: $20.

4. Extension hose Swivel Adaptor, for above, helps prevent kinks.

5. Extra Oxygen Humidifier: $15

6. Extra Oxygen Humidifier attachment hose $10

7. Extra Soft Silicone HydrOxy Spot Applicator: $10

8. Extra Water Infuser/Ionizer Bubbler stone: $4
(for bubbling water in container of choice).

9. Electrolyte (lye) Powder (each bottle enough for 2 fill, last 5 years): $24

10. Extra Drinking Water Bubbler 1 liter bottle (assembled): $20

11. Large Drinking Water Bubbler 3 liter Jug (assembled): $22

12. Drinking Water Bubbler attachment hose $3
(works with both versions of Drinking Water Bubblers)

13. Drinking Water Bubbler parts kit: $9
(so you can make your own Big Bubbler from your own plastic bottle(s)).

14. Leg bag: $20

15. Arm bag: $20

16. Mini-Torch KIT  that you can fuel with HydrOxy:
(Comes with torch handle, two orifice sizes, hose, plugs, fittings, etc.  Is useful for Health protocol 5).
You can do amazing things with the HydrOxy as a torch fuel-gas.
Manufacturers, jewelers and artists (that discovered it) have LOVED this gas since 1964.
It’s been one of the most under-appreciated and under-utilized technologies in America.  Asia has fully embraced it.

17. Tower Cap Upgrade Kit $100
Tower Cap eliminates the need for the silver filter on the front of the machine (when using the AquaCure for the first 4 health protocols).  Making maintenance simpler and eliminating the possibility of gas hose ‘plugging’ that sometimes happens.

18.  Hour Meter Upgrade Kit $50
Install an hour meter on the back of the machine (need to drill a 2 inch hole with a hole-saw).

19. Extra AquaCure Model EA-H160 Operation Manual: $25
For people who lose theirs (or just download from your Resources).

20. Registration to AquaCure Online Resources: $200
Registration is automatic and INCLUDED when you purchase an AquaCure from us… But some people acquire an AquaCure (as a gift, for example) and want to have access to all the ‘extra’ information, videos, etc.

HydrOxy is BIG in the Asia mostly because of the COST to build the machines in America For example, this company has made HydrOxy machines since 1964 and their machines do NOT have the same safety standards as the AquaCure design.  To implement ALL my safety features, I estimate they’d need to retail their machine at >$5000.00.

I’ve gone to Asia and imported a ‘basic’ reasonable quality electrolyzer (known as the VING) to use as the AquaCure ‘chassis’.
I then tear it apart and upgrade it with all the safety standards on this page (Standards I’ve learned from building and selling thousands of practical, efficient and innovative electrolyzers since 1984)…
and this allows me to sell a NEW SAFER, high quality machine (which I re-name AquaCure) at <$2,500.

This low cost AquaCure is a ‘game-changer’ because now most people can actually afford to use the amazing HydrOxy gas safely in their own home (for their plants, birds, fish and mammals).

AquaCure has long life, reliable electrical and electronic components and electrolyzer chamber.  Do NOT assume that because it ‘looks’ like a VING, that it is a VING.  It is significantly upgraded (at a cost several times higher than the VING retail).

AquaCure is CE safety certified, which I’ve then UPGRADED to pass CSA/UL standards.
Some manufacturers try to bypass this (expensive) certification by claiming that all components used are safety certified and while this is good (if true and includes the electrolyzer chamber too), it does NOT mean that the MACHINE as a whole is safety certified.

There’s no USA law that states any machine needs to be safety certified to be sold, but many business insurance plans require ALL equipment used in a building be safety certified.
If there is a fire, etc. and there is a SINGLE piece of uncertified equipment in the building (even a light switch that did not cause the fire), their insurance becomes invalid, even if they had properly kept up their payments.

Besides, wouldn’t YOU feel more secure using equipment that has been completely and independently inspected, tested and SAFETY certified to rigorous industry agreed standards?

In addition to all the above, we do our OWN multi-step testing on every single AquaCure machine, so there is NO QUESTION that it will perform perfectly for you.

AquaCure has a 2.5 psi electrical shutoff AND an over-pressure gas relief.

These are IMPORTANT safety factors because when water is turned into gas, it expands and  ‘wants to’ take up 1800 times more space.  If confined to a specific volume, (enclosed container without release) the internal pressure rises until the machine bursts and/or explodes.

If the HydrOxy is used as created, on-demand, there should never be a case where the pressure would rise too high…

BUT what if the gas output hose gets trapped (pinched) under a chair leg (as happened to me) or gets kinked under a pillow as someone sleeps…?

Over-pressure control is an important SAFETY feature.

Further, over-pressure control (along with an appropriate torch and backfire filter) then allows the HydrOxy to be safely used to fuel a torch; a nice additional useful feature to have.

NOTE: The original China basic chassis (VING) comes with 15-20 psi pressure, which is (in my opinion) DANGEROUS!
I’ve tried to tell them this but they arrogantly believe no one can ‘improve’ on their design.
Because of my DECADES of research and experience with HydrOxy, I KNOW this gas mixture is MUCH MORE explosive as its pressure rises.
At ambient pressure, a pop bottle can contain a HydrOxy explosion.  As the pressure rises, the explosion is logarithmically more powerful and at 20 psi, it’s like holding an M80 firecracker.

So I’ve changed their pressure switch to MY safety standard of ~ 2 psi, which, when combined with my other technologies, solves all the issues that demand they use up to 20 psi.  I do this for YOUR safety!

AquaCure uses a lightly caustic electrolyte mixture designed to achieve practical efficiency with minimal foaming and to promote long internal plate life.
(1 ounce of lye in about a quart of water).
This mixture IS technically caustic but can be safely used if appropriate care is taken.  It’s about as caustic as dish soap.

We’ve been selling ER50 electrolyzers optimized for health since 2007.  AquaCure is a new product for us, so we don’t yet have the articles and testimonials filled out specifically for it.  To see what HydrOxy (Brown’s Gas) has done for others, see the testimonials at the bottom of the ER50 Basic Kit sales page.
