A lot of us old divers already know a lot of the stuff Alec talks about, he just makes it so much fun to re-learn. Really enjoy his channel. Great job Kevin. Keep em comin.
Good Infomation...My Dive Buddy is an Instructor and has His own compressor. When He comes to visit He'll bring Me exchange tanks. He told me about how the filters work and like You, knows what He's talking about.I don't think alot of actually know what all it takes to go diving.
absolutely right. Another main source of noxious components in the compressed air stream is the compressor itself, any mechanical oil lubricated machine will finish to lose its oil, in the particular case of a compressor, the lubrication of the cylinders and the rings ends by the lost of some oil, that oil enters in the air stream and is compressed as a mixture in the following stages. on such a high pressure compressors, in the final stages, that oil acts as fuel and ignites causing combustion gases that is saaociated to carbon monoxyde and dioxyde plus unburned and vaporized oil that produces odors. it is a main reason why, on a breathing air compressor, it is imperative to use oil specifically formulated ( esters based ) for that application. As for any compressor, colder are the water separation stages, better is the result. excellent topic very good video ( as usual !!! )
That may have been covered in one of my Vintage Scuba videos. Can't remember which but that was a big problem with double hose regs. Will add it to my future ideas list for sure. A
Excellent information Alec i didnt know that molecular sieve was used in fineal stage of filtration at the scuba store when filling tanks thanks for this
Had a buddy get out of the water before a dive to re fit his CCR. Did it in the parking lot next to a running diesel truck and didn’t think anything of it…..until he’s 200 feet back in a cave and getting tunnel vision. I’m not a CCR diver but I believe he was getting bubbles and went to fix his BOV before the dive.
I did a video on buying scuba tanks and covered the SLC issue with these old tanks. Surprisingly they still appear in dive stores as garages are cleared out. A
Was wondering if you have a chance that you guys could go over the options of full face masks and how they compare to regular and regular mask work, would be a great watch....
Thanks for this very interesting explanation of comp-filter… about the Analysis Report that said CO is less than 0,5… does it mean there is still co in our tanks, but it in a safe level for breathing
Yes. It’s near impossible to remove 100% of any harmful substance but testing standards have agreed on safe levels. Only by getting air tested is a LDS sure their air is safe. A
Often when the result says less than X ammount, it is because the test equipment can't measure an ammount below the specified value. Rather than say somethig ambiguous like undetectable, they say less than the limit amount because as alec said the value will never be 0 but they are unable to measure such a small ammount.
That is something very specific and which I don't have access to a shop that does manual refills. All the stores I have visited use replaceable cartridges. Sorry but not able to show that. A
In my garage I have a Shop Compressor. Fills to 150 psi. The air coming out of the Twin Cylinder pump will Burn you. They use a Copper Tube from the Pump to the Tank. Manual drain for Water on the bottom. And a Water/Air Separator on the Output side. I can only imagine how Hot the air comes out of a 4k Psi compressor.
Just as hot as a big one. There is little space to cool anything down which makes small ones more sensitive to changes and more maintenance in my view. A
Looking at a old hooka it looks to be a strait compressor running on a float with a water trap so is this more dangerous I see a lot of people use them on their boats? what do you know about dagar rays? they seem to be between scuba and rebreathers
Not familiar with CCR''s like Dagar as they are evolving quickly to be safer and easier to maintain. Hooka floats come in many styles but are gas or electric powered. Like anything involving breathing underwater, know your gear and be safe is key. A

Couldn't agree more!

Glad you like it and hope you learned something too. Thanks for watching.

Than you sir and for your support.

Excellent informative video Alec and Kevin. Truly appreciate your channel.
Glad you enjoyed it.

Hi Alec, thanks for a great explanation of the air compression & filtration sequence of operation!
Glad it was helpful!
A
Thank you for this education! Love your content! Can you tell us a bit about why it is harder to breathe through a regulator when you are upside down.
That may have been covered in one of my Vintage Scuba videos. Can't remember which but that was a big problem with double hose regs. Will add it to my future ideas list for sure.

Oh no. That’s a dangerous situation to be in. Hope he learned to check his area before opening up a car.

This is a great video, lots of great stuff 👍, the compressor information was spot on, and really enjoyed this video.
Thanks 👍
A
👍😎🇵🇭Thanks Alex always enjoy your videos 🤿!
Glad you like them!

Interesting!
It is!

Great video! Sadly, our Coltri compressor is giving us a lot of headache :)
Oh no! They can be sensitive or downright cranky sometimes.

Surprised I haven't seen a Video about older aluminum cylinders like ones Marked SP6498 or ones made from the 6351 Alloy

Hi Alec, can you please make a video on manually refilling the bauer filter P21 or P31 cartridges with molecular sieve and activated charcoal?
That is something very specific and which I don't have access to a shop that does manual refills. All the stores I have visited use replaceable cartridges. Sorry but not able to show that.

Hey Alec can you do a video on sidemounts?
Will add it to my future video list. Thanks.

Do it bro . Not worth only talking
Ok.
Me I pipe in air from the mountains
🏔 🌲
Nice. I like my scuba air with a hint of mountain breeze!
