Hi David, glad it was helpful.

[@SK-me9by]

For those new to this type of compressor. That unit there goes by many brand name stamped onto it nothing wrong with that but you should know. Now the most important thing is just because the packaging states no oil or water needed you must still do pre maintenance and even a partial rebuild down the road relative to how often you use it. These run hot so us in the pcp air rifle world have learned not to push it. Sure it can do up to the 4500psi in a 0.5L as stated in the manual. We recommend running it up to 7 or so minutes Not 10 not 15 but around 7 or 8 minutes a session. Depressurize the line and w/fan running let it cool back down to room temp. Keep any metal to metal moving (talking about the bracket from the motor to piston rod) greased. Consider this a very light duty compressor and with some TLC you may get several years out of it. My first one was D.O.A and had to be replaced (metal to metal very nasty friction sounds) the one bearing on the motor bracket adapter was not properly greased or aliened. Have fun Be Safe high air pressures are no joke.

[@AlecPeirceScuba_SeaHunter]

You're right, high pressure air is not a toy. Be careful and safe always. Thanks for sharing SK. A

Thanks Darryl, It makes a great dive knife too!

[@toestr2120]

This looks like a branded version of a Chinese compressor you can get on eBay (there are several, with the Yong Heng being the most ubiquitous). Not sure I'd trust the activated charcoal and molecular sieve to be much more than regular charcoal and clay beads. Personally I think I'd go for a used shoebox compressor since it's made in the US and the maker was well known in the paintball industry. Also, is that tank TC approved?

[@AlecPeirceScuba_SeaHunter]

There are so many similar or white labeled products, this may be that but its better made than most and works.

[@Jetfire108]

Pretty interesting dive kit it would make a good back up system

[@AlecPeirceScuba_SeaHunter]

I think so too.

[@allenhilburn8686]

Having to use a new filter for each refill makes it sound like you will be going through a ton of the active coal and molecular sieve.

[@AlecPeirceScuba_SeaHunter]

Depending on how many times you fill it, for sure. Think of this as a backup to filling from a full scuba tank.

[@Lordvader330]

Well that thing is cool.

[@AlecPeirceScuba_SeaHunter]

It is cool. We talk a lot about new regs, etc but an affordable, compact compressor to fill tanks from 0.5L to 2.0L is amazing. Thanks for watching.

That is cool Alec I think I am going to purchase one of those. Thank you for sharing!

[@AlecPeirceScuba_SeaHunter]

[@wormhole331]

I use one of those cheap yong heng compressors on Amazon. Haven’t used it a lot yet but works fine. Just gotta give it a break once in awhile. It has the same filter setup as the compressor in the video but with only a fiber filter. That’s definitely ni enough so I bought two of those 12 inch filters that have refillable cartridges. I use the fiber filter first then daisy chain a 12 inch half full of silica to remove moisture. Other half is 13x molecular sieves to capture any fumes from the compressor and I believe they also capture carbon dioxide and carbon monoxide. The second long filter has is 1/4 full of more moleculer sieves and the rest activated charcoal. Air comes out with zero smell or taste. You can also buy a cheap foundry to reactivate the sieves and charcoal but haven’t tried that yet. I’d recommend to anyone using these small cheap compressors to upgrade the filter setup.

[@chiranagheorghitaeugeniuth98]

"13x molecular sieves to capture any fumes from the compressor and I believe they also capture carbon dioxide and carbon monoxide" yeah... some miracle fumes from the engine and maibe CO2 and CO :))))))))))))))))))) I hope you get my point and go take a proper scuba class and fill your tanks with a proper scuba compressor or in a trusty dive shop.

[@wormhole331]

@@chiranagheorghitaeugeniuth98 what do you think scuba shops use?! They use compressors that use oil just like a small one. And I’ll give you one guess on how they filter that air.

[@chiranagheorghitaeugeniuth98]

@@wormhole331 Yes I am totally agree with you. They use SCUBA compressors not aliexpress compressors and they use proper scuba filters on those compressors, some of them are rebuildable, some of them not, but the manufacturer of the proper SCUBA compressor offers the rebuilding materials not a company that rebrands some shit out of aliextress/china and sells it as mini scuba/dive system.

[@wormhole331]

@@chiranagheorghitaeugeniuth98 it uses all the same principles. Scuba shop compressors are just beefed up versions. They use the same materials for the filter media. Hell alec has a video on here with small gas engine ran compressors. That’s riskier than electric powered. I will say that No one should fill their own tanks unless they do the research

[@AlecPeirceScuba_SeaHunter]

Thanks for the feedback and for watching.. Others will have comments I'm sure about the filters.

I got one of these type compressors for a little 3Liter. Can confirm they work and air tastes great but I have a slightly upgraded filter

These little tanks are fine for their intended purpose, short & shallow dives. Like everything from scissors to cars, up to the owner to know and understand the products safety and operating procedures (I know it's a lot to ask). Thanks for watching. A

[@nitroxdiver461]

quite a interesting little gadget, wonder how long that would take to fill a al80 lol

[@nilotubes]

I checked the specs and i believe it mentioned 12 minutes to fill a 0.5l bottle, (was some hours ago) so about 4.5 hours to fill a AL80 (11.1l). Also the filter was for one filling only (0.5l), so you would need to replace the filter about 22 times for one fill of an AL80 :)

[@Atrinax]

@@nilotubes it will take more than that I guess, since when the pressure in the tank rises it takes more power to add additional gas? Correct me if I am wrong.

[@nilotubes]

@@Atrinax Maybe, not entirely sure, my compressor has a kind of fixed fill rate regardless of pressure, maybe this one does not? Anyhow my point was this is a kind of useless compressor for anything scuba. For filling suit gas bottles, I would rather then steal some gas from my other tanks with a hose

[@Atrinax]

@@nilotubes I am happy that smart guys in the comments point out that it is more efficient to use bigger tank to fill a smaller tank. There is a comment that says that you better spend only $100 on AL80 and spare air than invest $1000 in this high maintenance gimmick.

[@AlecPeirceScuba_SeaHunter]

Your going to need a 1st stage, either rent, borrow or buy. Also your 2nd stage needs to be balanced to the Intermediate Pressure from the 1st stage. So having a complete unit, serviced and balanced will make your diving much easier.

Looks ok ... BUT ... how long does it take to fill the little tank , let alone an AL80 or so ... keep the awesome videos coming ... Great Job.

[@AlecPeirceScuba_SeaHunter]

Manual says its only rated for up to 2L or 10 cu/ft. They have bigger models for 80's but that may be for another day.

[@klixtrio7760]

Although the compressor it neat, I don’t think it’s practical. They say the compressor uses 280 Watts and runs for 20 minutes to fill the tank. About 23 amps running on 12V, using 8 amp hours per fill. Most car batteries are around 50 amp hours, only a few fills and hard on the battery. The filter media costs $50 and lasts for about 50 fills. Not sure how often they recommend replacing oil but it costs $30. Probably adds a couple dollars to each fill. The worst part is the price. It costs over $1000! For that money you could buy a aluminum 80 and a spare air. Use the 80 to fill the spare air and pay a dive store $10 to get a over a dozen fills on your spare air. No compressor repair, no oil changes, much less possibility of breathing bad air, and cheaper. The 80 also holds its value much better or use it when you upgrade to full scuba gear.

[@rayanefree5790]

Agree, simply inefficient.

[@AlecPeirceScuba_SeaHunter]

Good points but the one key point the compressor is for filling mini tanks up to 2L or 10 cu/ft only. Anyone can try to fill a 80 cu/ft but you will probably be a lot older when it fills. Thanks for watching KT.

[@klixtrio7760]

@@AlecPeirceScuba_SeaHunter Hi Alec, I meant a cheaper alternative would be buying an aluminum 80 and have a dive store fill it. Then fill a spare air with a fill adapter :)

[@Xxxxx3x333]

Is it possible to bring this mini compressor in a plane for traveling? How much it weights? Amazing videos!! 😁

[@AlecPeirceScuba_SeaHunter]

I don’t see why not, nothing dangerous about it A

[@BakaNewsNetwork]

I am a Padi Advanced diver. I'm interested for safety reason. I use an airbuddy dive compressor and have only on air supply and no backup (airbuddy is limited to 12 meter). Having a mini emergency bottle in case of failure or air depletion can save your life or can make you go out of water without make an emergency ascent if you are in low deep water. So after 2 years, how about this product ? Safe to use with the mini compressor (no air quality problems ? (I will only refull at home with 230v so no gas problems). In fact, good video and explanation.

[@AlecPeirceScuba_SeaHunter]

If you're doing regular scuba dives greater than 10', a hooka or surface supply with a redundant reserve setup (tank & reg) is a good solution. Anything deeper/longer, go full scuba gear for safety and good air from a LDS. Being safe is smart. A

[@ephraimwiesel2110]

Surprised to see you dont have a scuba knife in the kitchen .😉

[@toriless]

I have lots of knives (somewhere between 40 and 100) in my kitchen and none are SCUBA ones. I keep that in my SCUBA kit along with one of my medic scissors.

[@AlecPeirceScuba_SeaHunter]

Oh I do have them lying around. Open my knife drawer and there may be a 8 inch US Divers in there, just in case.

[@Alvinyokatori]

How does the air taste from them little filters?

[@AlecPeirceScuba_SeaHunter]

No taste at all if filled properly. For shallow dives it fine. A

[@Josh-oq2kw]

I dove last week with someone who slings a 6cf spare air which I found ridiculous until I saw his low sac rate. He can get five minutes from one unless you account for duress maybe adding some additional breathing requirement. I suppose it's reasonable to a handful of people as a better than nothing option. The majority of divers would be much better served with a larger pony bottle. The mini integrated scuba systems are only good for certified divers who want to do three minutes underwater for some reason. (Getting something off a boat propeller?) They seem dangerous for anyone else, though I don't know of many reports of related issues, because it required a bike pump in the past. The ability for the untrained to refill them easily and put themselves or their families in danger only exacerbates the issue of misunderstanding pressures near the top of the water column or trying to extend a free dive by holding a compressed air breath.

[@AlecPeirceScuba_SeaHunter]

Good points Joshua. Like many mini tanks, this is a limited use for short and shallow dives or a BC vest inflator if your a vintage diver. Many items in our lives can be dangerous when not used properly: example cars, guns. Just read smart phones taking selfies kill 4x more people than sharks. We still use them right?

[@drewrose2750]

The hand pump that came with my Dedepu setup is absolutely horrid. I'm 25 years old and build strong and it's insane to use. Not even worth using. I'm looking for an electric pump that is on a good Budget! Love your videos you got my sub!

I can see this used as an emergency water egress system for aircrews flying helicopter overwater operations or small seaplanes that have a tendency to flip with improper landing technique.

This was a good unit. I have seen many, many compressors both small (like this) up to commercial units. For filling mini tanks, perfect!

[@chiranagheorghitaeugeniuth98]

The best thing I would use that compressor would be for car tyre inflation and that mini tank would look slick as a argon drysuit inflation bottle :) And one more point here: I saw a couple of vids on these toys but this is the most dangerous to put up there. What is your sincere opinion about you doing this: You are promoting a compressor + tank + reg to the wide untrained world.Why a dive store would not fill your tank unless you put cards on the table and check your tank inspection? Why a dive store would never rent regulators to uncertified divers? Why rebresther companies will not even sell you a rebreather unless you prove you are certified or during training? Than why do you accept these companies and this one specifically. It is like " we will sell everything for someoane to be able to kill himself very very fast". I refused to show to my father-in-law how to use dive gear because I am no instructor and he is uncertified. Would you? Really curious on your argument here. Do not get me wrong , I admire you a lot and you have some pretty good info in most of the vids but I really do not agree to what are you doing related to these products....They are dangerous and there are a lot of stupid people in this world. Just and example: someoane will fill that tank with that compressor near the car thatvhas engine running, not drainingvthe battery, and will put some carbon monoxide inside that tank. After that that person will take that underwater... I think that chances that his wife and 2 kids to light up some candles in the same day are very very big, indirect proportional to the size and wheight of that "scuba tank"..... does this ring some bells?

Completely agree, I admire the work of Mr. Alec on educating us but this is a dangerous product to advertise.

[@toms4022]

I knew there would be these comments.. guys these products have been out there for years and there are many brands.. at some point you have to accept they are here to stay.. there are inherent risks with many activities that can lead to injury or death and we have to trust people will read and understand the product they are using, I see people using these in shallow rivers, I haven't yet read about anyone using it as a primary air source for open water diving .. dive hookahs have been out for even longer than these and people successfully use them. The dive community needs to ease up a bit and welcome the innovation.

[@chiranagheorghitaeugeniuth98]

I know about hookahs but do not compare. The hookahs are used in conjunction with a dive operator or some of them, which are very dangerous for non divers, are a floating gas engine with a tube that goes to the diver. But this "pony" is ridiculous. With the hookahs the out of air is less probable, at least with a full tank and engine running , but with this... 5 breaths and you are out and in panic. I hope I will not get the chance to read a death report on DAN about these..... Yes they are on the market for some time but they were coming with a hand pump and after pumping 1/4 of a cylinder everyone would have thrown them away , but now with a chinese compressor? with no proper filtration? I knew a guy who was breathing from a oil contaminated cylinder. Imagine what happened in 3 years with him... We had an accident in our country with 2 "specialists" that were in the water with less than minimal equipment. Imagine what happened to both in 3 meter water. And now a complete filling and barely minimal diving apparatus is being sold to the wide public... crazy times. Accept and agree with these??? Let's go back than to the J-valve and no SPG or computer.. it's much safer. I strongly think that the international safety organizations should put a ban on the sale of these. People back 20 years ago were much more careful with their lives and used to read the manuals, now almost 80% don't even bother tacking the manual out of the pouch. Come on what are we talking about. Have the agencies do a pony diving intro course and yes, than it would be great. I see divers first time in dry suit, uncertified for dry usage, that put 25 kg of lead on them... and they at least have an idea about diving procedures and diving dangers. When accidents will start to arise because of these chinesium products the entire diving industry and diving community will be put in a really bad light, regulations will become absurd, and so on... and why? To put some money in a stupid chinese company's pockets?

If you want to use it during snorkeling for something in the deep you will be limited too.

If one doesn’t have a large compressor, this would do the trick for quick adjustments on the first and second stages or for checking performance after doing a service on your regulator set. All my regs are pre- 2000 and are simple enough to do myself(contrived). This would work for IP and breathing checks on 1st and 2nd stages. 🤷🏻‍♂️

This rumbling on is just horrid

Lots more to check out.

Why did you not do an air quality test on the system? Send it in for analysis? What is the time to to fill an 80 cf cylinder? Did it die trying to fill a 80 cf cylinder? You were marketing this set up, seems you are? You are not Really telling what we need to know or was that the point. Market this system.....

[@AlecPeirceScuba_SeaHunter]

The largest size tank the compressor is rated for is 2L or 10 cu/ft, and 80 would take a loooong time. As for air quality, if used right for short and shallow no air test is needed. I'm not marketing this, note there are NO links in the description to Amazon or the maker. This is information only. Thanks for watching U.M.

How long can you run it for before it over heats

[@AlecPeirceScuba_SeaHunter]

The compressor has a temperature monitor to stop when too hot. Manual does not say what temp is too hot. A
