Scuba Diving Lessons : How to Refill a Scuba Cylinder


So, this is to show you how to fill a scuba
cylinder for use underwater. This should only actually be done by someone that knows what
they’re doing, an expert, and one of the first things that you want to make sure that you
recognize is how what pressure that you’re going to fill the cylinder to. So, in this
case, this is an aluminum cylinder, and the working pressure for this cylinder is three
thousand PSI. Now, what we want to do is check and make sure that there’s actually an O ring
in the tank. And we go ahead and slide our whip on to the cylinder. The next thing to
actually do is close the bleed valve of the tank. And at this point, you could go ahead and
turn on or open up both valves. And actually let air into the cylinder. Now, with our compressor system, this fills
eight tanks at a time. And we would then go ahead and turn on our compressor and when
it hits three thousand PSI it’s going to stop.

  1. why the hell is this video even on here, the only people that should be filling the tanks would be the employees. Which a pre-existing employee or manager would teach a person who was just hired to fill tanks. This video is completely useless.

  2. Yes, it would fill your paintball cylinder. Many people use scuba cylinders for paintball. These cylinders come in various sizes from a few cubic feet to over 100 cubic feet (the cylinder in the video is approximately 77 cu ft.)

  3. I appreciate this. My boss says "I only explain things once. If you screw up you're gone." So put more scuba stuff on here please!!

  4. @NauiDiver91 Why would say your appauled at this video? Then post that you over fill aluminum 80s the tanks that have actually killed people. Your not really a diver your a wanna be.

  5. @cue1go I have never been asked for my C-card to buy a tank. I have 7 of them and like I said I have never been asked to show that I was indeed a diver Same go's for the day that I bot my diving air compressor…….

  6. @scubaflier1 there is nothing wrong with filling brand new aluminum tanks to 3300 read the manufactures book nd wanna be diver? im an advanced rescue/nitrox diver so yeah im a wanna be

  7. You're only required to show your c-card when buying air. It is not necessary to posess a c-card to buy equipment (tanks, compressors).

  8. @divetech11 I think the people who made this are assuming that the tanks are all recently tested/made and have been drained completely.

  9. 1) You must be a certified Fill Station Operator (FSO)  to fill compressed gas cylinders over 40 PSIA. 2) inspect the hydro date to make sure the hydro is current (within 5 years of last hydro for most cylinders), 3) check the Visual Cylinder Inspection/Evidence of Inspection (EOI) label to make sure it's current – within one year, 4) give the cylinder and valve a quick look over to ensure there is no obvious damage: warped, heat damage, dents, etc 5) 'crack' the cylinder valve open briefly to blow any moisture/particulate from the cylinder valve opening, 6) 'crack' the fill whip valve open briefly for the same reasons as #5. 7) Connect the fill whip to the cylinder, close the fill whip bleed valve and open the cylinder valve. 8) the fill rate should be between 300-600 PSI/minute. 9) Best to keep all personnel out of the area in case of a cylinder, fill whip, etc failure – 90% of all cylinder failures occur during filling. 10) If you must stay in the area wear hearing protection if filling from a nearby compressor and make your stay in the fill area as brief as possible.

  10. so, i just started working at a dive shop. the owner has me filling and inspecting tanks and i have absolutely no experience. the only training ive had was a one hour tutorial by one guy and if i have questions ill call the owner. i dont feel safe doing this, im not sure if the air going into the tanks is good air and i'm worried about someone getting hurt. i don't think i can do this anymore.

  11. what about us who are far from Europe there are no refilling stations can we use our local compressors which we used to refill the car tyres?
