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.

Cool unit for a back up safety system! Thanks for sharing

I was looking how filling the tank but not manually and this is great. Greetings from Mexico.

I miss good old vintage scuba videos. Great videos as always.

Thank you Mr Peirce for keeping us informed

[darrylblondel]

Looks well made. Probably high maintenance, filters and o rings exetera. Handy in remote diving places. I like your technique of opening parcels Alec. 😆👍

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.

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?

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.

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

[ncwarrior]

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

[nitroxdiver]

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

[klixtrio]

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.

I bet that knife reminds you of your first dive knife.

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.

[Dreoni_]

New diver here, love your videos and have learned quite a lot! One question, will dive centers give me the stink eye if I only travel with a second stage instead of the whole regulator?

Muito bom para ser utilizado como reserva, pequenas intervenções. Muito maneiro o
