Hast du noch einen Filter eingebaut? Habe gelesen, dass diese unbedingt noch eingebaut werden sollten. Es stand etwas von einem 10µ-Filter mit Wasserabschneider nach dem Kompressor und zusätzlich einen 20µ-Filter direkt vor der zweiten Stufe.
Zwei Filter wäre absoluter Overkill und kostet nur Leistung, einer reicht vollkommen. Wir arbeiten hier mit wesentlich geringerem Druck als bei konventionellen Pressluftgeräten nach der 1. Stufe. Jeder Filter bedeutet Druckabfall. Kondenz ist bei dem geringen Druck auch kein Thema. Vor und nach Benutzung ca. eine halbe Minute durchblasen lassen, damit mögliche Feuchtigkeit beseitigt wird und das Thema hat sich erledigt.

@@e-mat6077 ah, the vent pipes! I think they have virtually no pressure handling capacity- at least the straight pipe. What has your experience been? What is your relief valve set at?
@@en2oh The pressure release is triggered at 1 bar, which this compressor can barely reach. You need to keep in mind that this kind of compressor is designed for high volume output, not high pressure like for example a tire inflator. I did a separate stress test, filling the reservoir to 3 bars (using a different pump) without any issues, so there´s plenty of safety margin. It could probably stand a lot more, but I didn´t want to break it just to find out how much more.
Hi, did you ever try with the Maisi compressor you advised for 2019. As that one has no cooling ribs I am wondering if it can be cooled enough. Thanks.
I haven´t yet used it for building a new version, but having more power, the amout of heat it produces will also be somewhat higher. A strong enough constant airflow around the compressor is essential. Adding some fans with enough power and designing an efficient airflow path might be the way to go.
Hi awesome job. I'm trying to decide what type of lipo to buy. You recommend 12v 30AH, how long does that run for? If I went cheaper 12v 12Ah how long would it run?
It depends on many variables like temperature and resistance. The deeper you go, the more resistance, the higher the current draw. It´s always better to be on the safe side. You need to do your own research and then add a sufficient safety margin. Even though Lipos have great capacity, they are not the safest option because their BMS will automatically cut off the power once the minimum voltage is reached, so you need to stay aware of your battery status at all times.
I'm a little confused with the max Presure indications for the compressor. For instance, the "recommended version 2019" compressor has a max pressure of 1.85bar (26.83 psi). Does that mean I cannot fill my PVC air reservoir to anything more than 1.85 bar? The PVC reservoir coild easily hold 150 psi safely, and the 2nd stage regulators are normally rated for 145~150 psi. Also, I see you did not include an Air Pressure Switch in the list of materials, does that mean the compressor has a built-in pressure switch to automatically turn off/on? Or are you just running the compressor non-stop until the battery dies?
You need to use a second stage especially adjusted for hookah diving. They run at much lower pressure than the ones used in regular scuba applications. Yes, it means your reservoir will be filled with the amount of pressure that the compressor is able to produce. Storing large amounts of air is not the idea of the reservoir, but to improve breathing comfort by buffering air for your next breath stroke while you are still exhaling from your previous one. That way, you can get away with a compressor about half the size that you would need without a buffer tank. With the setup used in this video (ACQ-903 compressor), adding a pressure switch wouldn´t make any sense because in actual use, the compressor needs to run constantly. You wouldn´t be able to switch it off for more than 1-2 breath strokes without drastically increased breathing resistance. Also, the compressor´s max pressure is way below what could cause structural harm to the buffer reservoir. However, the 2019 compressor recommendation is more powerful. I haven´t yet been able to test how much excess it would produce, but it´s possible that a pressure switch might make sense. An even better solution would be to have it run constantly but adjust its power based on how much pressure there is in the tank. That would require an additional control circuit. However, if you want to keep the setup as simple (and reliable) as possible, then an overpressure valve for simply venting any small amounts of excess air might be a good alternative.
He great system. I'm planning to make a hookah diving rig my self. Im locking ad a compressor similar to yours but instead of 70L/min this one puts out 160L/m an has 0.02MPa more (i dont think that 0.02 is going to make any difference). The only thing I don't understand is how deep you can go on ... MPa, PSI or Bar. And would you recommend a small airtank Like your ring?
You need to look at the curves which show how much output in liters you will get at what pressure. For example, at 5 meters the compressor needs to overcome 0.5 bar of pressure, at 10 meters, it will be 1 bar. At the same time, the volume of the air that the compressor is able to supply, will be reduced by 1/3 at 5 meters and by half at 10 meters due to the surrounding pressure. One diver needs about 15-20 Liters of air (at depth) per minute, depending on physical activity and individual properties. So as an example, if you want to dive to 10 meters, it means that you would want a compressor that is able to supply 40 liters per minute against a pressure of 1 bar. By the time the air is pumped down to 10 meters, its volume will be reduced by half, so the diver will have 20 liters to breathe per minute. 160L/min might make it possible for you to supply two divers at the same time when at shallower depths. With only one diver, you will be able to go a bit deeper, but not not much more than with the smaller compressor. I can´t give you any precise calculations without seeing the exact specs and curves, but my guess is around 7-8 meters. A buffer tank is an absolute necessity. Without one, breathing comfort will be a lot worse and maximum diving depth will be greatly reduced.
@@koenmastbergen9216 The floating ring serves as a buffer tank. The compressor is pumping air directly into the floating ring and the long regulator hose is connected to the bottom of the floating ring.

I understand that this might be frustrating for those who could find the plans useful and would use them responsibly. On the other hand, those who do have the necessary knowledge and skills might find this info useful for making their own construction, even without any of my plans. After all, it´s a relatively simple device, but you have to understand what you are doing and be aware of all potential risks.
Thanks! The files are not yet 100% ready to be used as such, there are still a few minor details to be optimized. Once finalized, I will need to reach a decision on whether or not to make my design available and in what form.
Sorry, you need to do your own research then. You´ll also need to take other issues into account like avoiding exhaust gasses from entering the system.
You can adjust it to fit the pressure of your compressor. Adjust it until it closes at exactly the maximum pressure that your compressor produces. No air is supposed to flow unless you inhale. I also changed the hose on the regulator for a wider one with 10mm inner diameter. It will improve breathing characteristics.

The plans are not quite finalized, which means that not all of the parts will fit perfectly, but they require some manual modifications and adjustments for them to fit and work properly. It´s definitely not a plug-and-play device and all those who decide to use one need to have at least some kind of diving background as well as a decent understanding of the function this rig and be aware of all possible risks.

Ja habe direkt angeschlossen haste aber ich habe auch eine große schlauchtrommel verwendet ca 20 Meter an Garten Schlauch und ich habe dort auch kein immensen Unterschied festgestellt
Eine Schlauchtrommel bringt nichts. Du brauchst einen richtigen Druckbehälter dazwischen mit genügend Volumen (ca.15-20 Liter) als Puffer für mehrere Atemzüge Luft. Dann kommt auch genug. Ich habe bei meiner Version den Schwimmring zugleich als Luftbehälter benutzt, d.h. die Luft vom Kompressor zuerst in den Schwimmring und dann den Schlauch zum Atemregler direkt am Schwimmring anschliessen. Du kannst aber anstatt des Schwimmrings genausogut eine andere Art von Behälter benutzen, hauptsache genug Volumen und stabil genug. Bei der Wahl des Behälters unbedingt darauf achten, dass er den Druck gut (mit grosszügigem Sicherheitsfaktor) aushält. Ich habe meinen Schwimmring mit einem Überdruck getestet, der dem dreifachen Maximaldruck des Kompressors entspricht.
@@victorvinasco2070 It depends on your compressor. The one in this video ACQ-903 produces only enough air for one diver. For two divers, you need a more powerful one like ACQ-910 or Maisi.

@@e-mat6077 assuming that the compressor (that's a single chamber design) delivers more than 50lpm and the air reservoir is suitably pressurized, a second hose can be added. Depth will be more limited.
@@en2oh That would require a more powerful compressor than the one used in this video (ACQ-903), which can theoretically provide 70l/min, but with zero counterpressure. That output will decrease drastically even at very shallow depths like 1 meter. That compressor is the absolute minimum to just barely sustain one diver and there´s absolutely no way you could use it for two. However, the next bigger models (ACQ-906, 908 or 910) should have enough power to supply two divers, but of course at the expense of maximum depth.
Are the files available for purchase? I've been looking for a personal hookah diving system but they are all insanely expensive. This is by far the best option available.
The files are still at a prototype stage, so there are some details which are not 100% optimized. I haven´t had much time to work on this project lately due to what´s going on in the world right now. The files could be used, but they are definitely not plug-and-play.

Just take off the regulator hose (open the quick connector underneath the tank) and run the compressor for a moment, it will blow everything out. Or leave it open for a while if you´re not in a hurry.
I haven´t had any issues. It´s important that the comressor head with its cooling fins is exposed to the open air. The part of the compressor which is inside the enclosure is also surrounded by a constant airflow because all the air that the diver uses is sucked in through the snorkel and into the enclosure before it enters the compressor. So the air inside the enclosure is constantly changing and there is no heat buildup. The outer walls of the enclosure are also kept cool by the surrounding water.
Hey my dear I want to build it same as you but the compressor link in your info box is for a 220 volt but we need a 12 volt one and the second point is you don't have functional link for the tube and the thing which goes into the mouth Yours faithfully robin
All the compressor links in the description are 12V, not 220V. The tubing was bought locally. The size I used is 14mm/10mm (outer/inner diameter). I updated the broken link to the regulator, it should work now.
Kaikkimuumit Laaksossa moin habe gerade herausgefunden das du deutscher bist habe mal ne Frage habe als Budget 120 Euro habe schon ein akku.

Nein, bin ich nicht - aber zu deinen Fragen: Ich glaube nicht, dass es denselben Kompressor in Deutschland direkt gibt, aber du kannst ja mal bei ebay oder Amazon suchen. Wenn es diesen dort gibt, dann wahrscheinlich nur mit Lieferung aus China. Gartenschlauch empfiehlt sich nicht unbedingt, da diese meistens aus PVC sind, und alle möglichen Lösungsmittel enthalten. Silikon in Lebensmittelqualität wäre eine gesündere Lösung, aber da muss man widerum aufpassen, weil solche Schläuche eher zum Umknicken neigen da das Material weicher ist.
Habe den kompressor nicht bei Ebay gefunden naja dann werde ich wohl bei Ali bestellen wo wohnst du denn und hattest du Probleme mit dem Zoll und noch meine letzte Frage wie tief kann du den tauchen mit dem kompressor der hat ja 0.1mpa das ist ja das gleiche wie 1 bar theoretisch gesehen müsste man ja 10 meter tief tauchen können. So hohe Ansprüche habe ich eh nicht d hofft er aber 5 meter tiefe:) Vielen Dank für deine Hilfe ohne dich wäre ich nicht so weit gekommen.
Der Atemregler braucht Überdruck, um zu funktionieren und gleichzeitig genügend Fördervolumen. In der Praxis reicht es bis ca. 5m. Probleme mit dem Zoll sind nicht zu erwarten, es kann höchstens sein, dass Du auf den Gesamtbetrag Mehrwertsteuer bezahlen musst.
No mold whatsoever. I live in a dry climate and always vent it thoroughly after use, store it indoors in a dry heated space and leave the hose connection open until the next use.

Hola e-mat me gusta tu idea y quisiera armar un equipo como el tuyo pero vi en el mercado un compresor marca EInhell modelo te-ac 36-6-8 li of qué es inlambrico y funciona con 2 baterías de 18 voltios y ya biene con un tanque de 6 litros quisiera saber si lo conoces si se podría usar o si alguien que lee este mensaje lo conoce por favor opine gracias
The compressor you mentioned is very different from the one I used. The Einhell uses much higher pressure, but relatively low volume, so you would need to use a regulator with higher intermediate pressure setting. Also, I have no information about the internal structure of the compressor, so I cannot say whether the air it produces is clean enough (free of oil and particles) for breathing. If it uses pistons instead of membranes you need to expect some debris. You really need to do your own research.

The plans are not quite finalized, which means that not all of the parts will fit perfectly, but they require some manual modifications and adjustments for them to fit and work properly. It´s definitely not a plug-and-play device and all those who decide to use one need to have at least some kind of diving background as well as a decent understanding of the function this rig and be aware of all possible risks.
@@e-mat6077 Will you eventually release the 3D print files? I had a look at your Thingiverse account but doesn't seem like you have shared them there. I know it is up to you if you want to make the files public or not, but I find it strange that you put a parts list in your video description with links to buy all the stuff, but the stl files are not shared.
Hi, what is the pressure (psi) inside the floating reservoir? Thanks
With this compressor (ACQ-903) maximum about 1 bar.
Ja habe direkt angeschlossen haste aber ich habe auch eine große schlauchtrommel verwendet ca 20 Meter an Garten Schlauch und ich habe dort auch kein immensen Unterschied festgestellt
Eine Schlauchtrommel bringt nichts. Du brauchst einen richtigen Druckbehälter dazwischen mit genügend Volumen (ca.15-20 Liter) als Puffer für mehrere Atemzüge Luft. Dann kommt auch genug. Ich habe bei meiner Version den Schwimmring zugleich als Luftbehälter benutzt, d.h. die Luft vom Kompressor zuerst in den Schwimmring und dann den Schlauch zum Atemregler direkt am Schwimmring anschliessen. Du kannst aber anstatt des Schwimmrings genausogut eine andere Art von Behälter benutzen, hauptsache genug Volumen und stabil genug. Bei der Wahl des Behälters unbedingt darauf achten, dass er den Druck gut (mit grosszügigem Sicherheitsfaktor) aushält. Ich habe meinen Schwimmring mit einem Überdruck getestet, der dem dreifachen Maximaldruck des Kompressors entspricht.
E- Mat hello in the diving tank what are you doing can you connect 2 buses?
@@victorvinasco2070 It depends on your compressor. The one in this video ACQ-903 produces only enough air for one diver. For two divers, you need a more powerful one like ACQ-910 or Maisi.
Hi Great job, did you use 1 or 2 batteries..
One 12V 18Ah gel battery, for simplicity and reliability. The weight also helps to stabilize the rig.
Hi, how deep can you go with this? And how many hours can stay underwater?
How about reading the video description?
@@e-mat6077 sorry for not read correctly,, your compressor is for 5 meters but if a want one for 10 meters what I should by? Thanks
What size pvc do I use?
Hi, great job.
Did you test(or made) the two-diver model?
No not yet.
I choose to model (two divers for) : www.aliexpress.com/item/BOYU-electromagnetic-DC-vehicle-oxygen-pump-105W-pump-DC-12V-Elemental-O2-Air-Pump-Aquarium-Pond/32849967763.html?spm=a2g0s.13010208.99999999.263.3pwaiE
Will you be enough?
That one should also work ok.
@@e-mat6077 assuming that the compressor (that's a single chamber design) delivers more than 50lpm and the air reservoir is suitably pressurized, a second hose can be added. Depth will be more limited.
@@en2oh That would require a more powerful compressor than the one used in this video (ACQ-903), which can theoretically provide 70l/min, but with zero counterpressure. That output will decrease drastically even at very shallow depths like 1 meter. That compressor is the absolute minimum to just barely sustain one diver and there´s absolutely no way you could use it for two. However, the next bigger models (ACQ-906, 908 or 910) should have enough power to supply two divers, but of course at the expense of maximum depth.
Are the files available for purchase? I've been looking for a personal hookah diving system but they are all insanely expensive. This is by far the best option available.
The files are still at a prototype stage, so there are some details which are not 100% optimized. I haven´t had much time to work on this project lately due to what´s going on in the world right now. The files could be used, but they are definitely not plug-and-play.
Do you have your printer files posted somewhere?
Have you built the120 and 160 Hooka yet? thanks
Not yet as I´m currently busy with a few other projects. Hopefully soon.
I would love to buy one, please keep me informed
oh wow you are great job.. i would like to buy this.. how much cost is that i am live in orlando fl?
Thanks for your comment. It´s only a single prototype so far, which is not for sale at this time.
thank oh gosh....
How long did the battery last
I don´t know. Longer than any of my dives. At least 2-3 hours, probably more.
to what deoth can u go with the old version?
As the description says - to 5 meters.
How deep will that pump allow you to go
How about reading the description?
How long do you think that battery would last with the stronger compressor

Hallo, hätten Sie für mich die STL Datei?
Nifty
Tank condensation drain?
Just take off the regulator hose (open the quick connector underneath the tank) and run the compressor for a moment, it will blow everything out. Or leave it open for a while if you´re not in a hurry.
Does it overheat?
I haven´t had any issues. It´s important that the comressor head with its cooling fins is exposed to the open air. The part of the compressor which is inside the enclosure is also surrounded by a constant airflow because all the air that the diver uses is sucked in through the snorkel and into the enclosure before it enters the compressor. So the air inside the enclosure is constantly changing and there is no heat buildup. The outer walls of the enclosure are also kept cool by the surrounding water.
Hey my dear I want to build it same as you but the compressor link in your info box is for a 220 volt but we need a 12 volt one and the second point is you don't have functional link for the tube and the thing which goes into the mouth
Yours faithfully robin
All the compressor links in the description are 12V, not 220V. The tubing was bought locally. The size I used is 14mm/10mm (outer/inner diameter). I updated the broken link to the regulator, it should work now.
Kaikkimuumit Laaksossa moin habe gerade herausgefunden das du deutscher bist habe mal ne Frage habe als Budget 120 Euro habe schon ein akku. Der kompressor den du verlinkt hast kommt ja von Ali darauf habe ich net so Bock kannst du mir auch ein Link geben von einem wenigsten von Ebay oder am besten noch aus Deutschland und ich weiß du hast mir schon gesagt wegen dem Schlauch aber kannst du mir noch ein Link schicken bzw funktioniert ein einfacher Gartenschlauch für das Gerät
Danke: -)
Nein, bin ich nicht - aber zu deinen Fragen: Ich glaube nicht, dass es denselben Kompressor in Deutschland direkt gibt, aber du kannst ja mal bei ebay oder Amazon suchen. Wenn es diesen dort gibt, dann wahrscheinlich nur mit Lieferung aus China. Gartenschlauch empfiehlt sich nicht unbedingt, da diese meistens aus PVC sind, und alle möglichen Lösungsmittel enthalten. Silikon in Lebensmittelqualität wäre eine gesündere Lösung, aber da muss man widerum aufpassen, weil solche Schläuche eher zum Umknicken neigen da das Material weicher ist.
Habe den kompressor nicht bei Ebay gefunden naja dann werde ich wohl bei Ali bestellen wo wohnst du denn und hattest du Probleme mit dem Zoll und noch meine letzte Frage wie tief kann du den tauchen mit dem kompressor der hat ja 0.1mpa das ist ja das gleiche wie 1 bar theoretisch gesehen müsste man ja 10 meter tief tauchen können. So hohe Ansprüche habe ich eh nicht d hofft er aber 5 meter tiefe:)
Vielen Dank für deine Hilfe ohne dich wäre ich nicht so weit gekommen.
Der Atemregler braucht Überdruck, um zu funktionieren und gleichzeitig genügend Fördervolumen. In der Praxis reicht es bis ca. 5m. Probleme mit dem Zoll sind nicht zu erwarten, es kann höchstens sein, dass Du auf den Gesamtbetrag Mehrwertsteuer bezahlen musst.
What is the max diving depth?
How about reading the description?
Lol thanks bro👍
You ARE aware that visual inspection and cleaning for mold will be this rigs downfall.
How is the black lung treating ya?
No mold whatsoever. I live in a dry climate and always vent it thoroughly after use, store it indoors in a dry heated space and leave the hose connection open until the next use.
Kann man kaufen ? Preis ?
This is really cool, I just hope you have proper training before you you start diving more with it
What would make you think that I didn´t?
@@e-mat6077 I know nothing about you
I enjoy being alive way too much that I would take any unnecessary risks.
Ich habe genau solche Regulator auf Ali bestellt :)))
Hast du das gerät nachgebaut
Galvanised steel drain pipe would work.
Why not. Or even stainless steel, even though it´s more demanding to work with.
Hi again, i was very impressed with the cad and printing, did you do all that your self or did you get some one to do it for you, the reason i ask is i have a diving / scuba patented invention that i need help with..i have spent thousands on it so far but i need help.
Here is my Line Buddy on Facebook...facebook.com/LINE-BUDDY-403709290211468 you can contact me their..speak soon.
@@freemanchannel9222 All done on my own, many of the parts needed several attempts before getting them to fit and work as needed.
I would buy this..so can I?
It´s a prototype with some imperfections, so it´s not yet good enough to be sold as a product.
@@e-mat6077 So are you pursuing to market them ? have you seen the Air Buddy ? Its nice but way way to expensive I would pay in the neighborhood of 600.00 to 800 .00 It would need to go 20 feet and last 90 min or longer
@@nitro200flyer3 I´ll have to see how good it turns out. There are also quite a few legal requirements which need to be taken into consideration.
Hola e-mat me gusta tu idea y quisiera armar un equipo como el tuyo pero vi en el mercado un compresor marca EInhell modelo te-ac 36-6-8 li of qué es inlambrico y funciona con 2 baterías de 18 voltios y ya biene con un tanque de 6 litros quisiera saber si lo conoces si se podría usar o si alguien que lee este mensaje lo conoce por favor opine gracias
The compressor you mentioned is very different from the one I used. The Einhell uses much higher pressure, but relatively low volume, so you would need to use a regulator with higher intermediate pressure setting. Also, I have no information about the internal structure of the compressor, so I cannot say whether the air it produces is clean enough (free of oil and particles) for breathing. If it uses pistons instead of membranes you need to expect some debris. You really need to do your own research.
Perfecto gracias
How much
Hola, me interesaría los archivos en 3D, si no es molestia me los puedes pasar, me gustaría probar esa esperiencia.
how get 3d model sample bro
Some details of the design still need some minor adjustments.
Do you sell this ?
No. At this stage, it´s more a proof of concept than a finished product.
hello are you able to man made ??
I´m not sure what you mean, but so far only this prototype exists.
Kaikkimuumit Laaksossa you do not make it to sell?
are there any new experiences about the two diver prototype, you would like to share?
Not yet since I'm currently occupied with other projects but hopefully soon.
hello can you send me the computer plans i ordered the parts
Hello, sorry but the plans are not yet ready for release.
