Questions about this item:
The item arrived today but there is no user instruction.
I filled the tank through yoke filler, the gauge shows around 2000psi. Does that sound right? at 2000psi means it is full?
The H2Odyssey tank is a 3000 psi tank so it technically is not "full". That being said; did you check the pressure in the tank that was filling the H2Odyssey prior to the actual fill? I bet it was somewhere above the 2000 psi mark. Just remember that if you're filling from a larger bottle using the yoke fill setup then you will basically be equalizing the pressures between the two tanks. Since the H2Odyssey would be empty to start off with that void has to be filled. Basically if you take a specific volume of gas at a given pressure within a confined space (ie. the large bottle) and then add more space (ie. H2Odyssey's 6 cubic feet); said gas will expand to occupy the entire space, but will do so at a lower pressure as long as the temperature remains the same. This is just basic gas law practice. You can read more about it at Wikipedia by searching for "Gas laws".
Kuan H Hi Brandon
I have tried again
I checked my 15 LTR tank which was around 3300psi, the H2Odyssey was around 2000psi from the last fill.
I filled again through the yoke setup.
The H2Odyssey went up to 2500psi then slowly dropped to 2200psi. I couldnt get it to 3000psi.
I checked my 15 LTR tank again, it is now down to 2200psi.
During the filling process, lots of excess air went out from the yoke filler.
Please kindly advice why
Kuan: I had my H2Odyssey Extra Air Source 3 inspected and filled by a professional Scuba shop. It reads 3,000 pounds per square inch (psi). I suggest you contact H2Odyssey and obtain the instructions and have it inspected at a Scuba shop. My opinion about the pressure reading: 1) maybe the main air tank you used to fill your H2Odyssey had less than 3,000 psi. If this was the case, your H2Odyssey would read no more than the pressure in the source tank. Example: If the tank you used had 2,000psi, your H2Odyssey would read a little less than 2,000psi (approx. 1,750psi, if my math is correct). You are sharing air pressure from a 80 cf (source tank) with a 6 cf. (H2Odyssey), therefore the pressure will drop on the main tank and both tanks should read the same psi. 2) Or, you could have a leak on your regulators (or hoses)... I have a slow leak on my 2nd stage regulator. 3) Or, you may have a bad pressure gauge. Try installing another pressure gauge to the 1st. stage regulator (release all the air from the H2Odyssey or make sure the air valve is closed before removing the "plugs" on the 1st stage or you could experience a 2,000psi of air explosion on your face or worse) to verify the psi reading is correct. A Scuba shop can give you a better answer because I have not used my H2Odyssey for diving yet . Hope this helps. Happy diving.
Kuan H Hello Carlos
yes, you are right
I better take it to a dive shop for them to have a look.
many thanks for your help
Will airlines let you fly with these? Can they go in carry-on or need to be checked? Thanks.
GREGORY J I'm not sure; I've never flown with it.
JOSEPH S Yes. I have carried my on several times with no problems. I take the regulator off and put on the plastic plug.
TIM F Not sure about major airlines but the smaller carriers have let me travel with mine as long as it is empty.
how much air do you get ? 500psi?
Brett H This package includes a 6cf tank that will fill to 3000 psi.
I dive Enriched air and want to refill this at home, Can you fill it with Nitrox and is it compatible?
BRIAN H Hi Zach;
I am a air only diver, I should defer this to H2Odyssey customer servise/tech support. My training for Enriched Air is not yet complete, and from what I have learned from the tank manufacturers is that the tank of this unit arrives to the purchaser in Nitrox ready (clean) condition, once you put your equipment into service for one particular use (nitrox) , then it needs to stay in that particular use only (designated-labeled-specifically) . If you have the capability to fill tanks with enriched mixtures at home you must be an advanced diver ? My end use of this product was to mount the regulator/fill valve combo on a 19 cf bottle, remove the second stage from the side of regulator, attach standard octo setup, mount to side of main tank with X-Scuba's "Pony Tamer", I have 3- tanks set up with this, I beleive in a real redundant system. Wish you the best on working this out, good diving!
DANIEL V Hi Zach! I dive nitrox as well and to answer your question ,absolutely yes! This set is great and I take it on every dive with me.Everytime diving enriched air.
JOSEPH S The packaging for the EAS 3 indicates the kit has been cleansed for Nitrox. I only put Nitrox in mine.
EDWARD B Zach,
Since you are wanting to fill with a mixture less than 40% O2 the normal equipment standard do not require special handling, such as Viton Orings, etc. I would assume it would be fine. You may want to confirm with the manufacturer on this. My past experience with them is that they are readily accessible and will answer your questions.
I assume your interest in filling it with Nitrox is simply a function of whip filling it from your existing tank that is filled with Nitrox. The H2Odyssey is a "Bail-Out" bottle for last resort and nothing more. WIth only 6cf capacity it isn't intended to to be used as a stage or deco gas source. There is just enough to do an ascent from 100' deep assuming a normal ascent rate to avoid any issues.
DON H You may fill with Nitrox up to 40 percent off a regular scuba tank, or premix up to 40 percent. Hope that answers question.
TIM F Yes, and it is very easy.
What is the diameter of the tank? What is the length, with and without the reg attached? What is the buoyancy?
LeisurePro S This 6cu tank has a diameter of 3.2 inches and a length of 11 inches without the attached regulator (approx. 15 when attached). It has a buoyancy of -3 pounds when full and -1.2 pounds when empty.
1st and 2nd stage included in this kit?
LeisurePro S Yes, first and second stage included.
This product has a limited warranty of 24 months.
Whats in the box:H2Odyssey Extra Air Source Balanced Diaphragm 1st Stage, Downstream Second Stage, Yoke Filler Adapter, 6 cubic foot Tank, EAS Bag
You're 60 ft down, and your primary air source isn't functioning and you can't get air, what do you do? Pull out your Extra Air Source, calmly make your way to the surface, make a safety stop and once back on the boat or on shore thank God you dove with the Extra Air Source.
The Extra Air Source removes existing limits on redundant air currently on the market and allows you to configure a redundant air source tailored to your diving needs. Whether you're cave diving or diving shallow reefs the Extra Air Source will get you to the surface and even provide you with enough air for a safety stop if configured correctly for your maximum depth. The Extra Air Source3 Yoke Kit consists of the follow:
The EAS3 gives you the reliability of a redundant air system using a dependable environmentally sealed balanced diaphragm first stage with a downstream demand valve second stage. The First-Stage Regulator threads directly into the neck of a cylinder eliminating the need or bulk of a cylinder valve, it also gives you the latitude of selecting the size of cylinder to be utilized. First stage has a sure grip on/off valve hand wheel that is easy to turn even with gloved hands. First Stage has three low pressure ports and two high pressure ports and is manufactured from corrosion resistant forged brass with a black chrome finish. First Stage is equipped with an analog pressure gauge.
Second Stage Regulator has a bright yellow purge cover, is a dependable simple down-stream demand valve design which connects to the first stage via a 360° vertical/ horizontal swivel. The second stage has a quality silicone mouthpiece, diaphragm and dual exhaust manifold with dual exhaust valves for ease of inhalation/exhalation when in an emergency out of air situation. The large purge button makes clearing the regulator safe and easy.
System includes a lightweight 6 cubic foot aluminum cylinder that fits into H2Odyssey's Quick Release EAS Bag. The bag is the best way to mount your redundant air system. Designed to hold the 6 cu ft tank, the bag clips easily to your BCD "D"-rings. Bag is made of durable nylon material with two adjustable Quick Release Buckle straps.
Kit comes equipped with the handy yoke filler adapter. Adapter allows your ExtraAir Source System to be filled on the beach or where a compressor is not handy. Yoke Filler allows you to fill off of a standard scuba yoke valve, made of durable chrome plated brass and corrosion resistant materials.
