Tanks are filled using an air compressor capable of producing over 3000psi coupled with a filtration system that purifies the air to a level acceptable by the Compressed Gas Association as breathable air for scuba. This is not a "do-it-yourself" project - Scuba Diving facilities are certified to fill tanks. Trying to do this yourself will result in deadly gas mixes and overfilling can rupture the tank or valve - in addition to harming (deadly results) anyone in the immediate area.
You would need about 2000-3000 PSI of air to fill up a tank, but this varies from tank to tank. Some tanks with a DIN valve can go up to 4000 and 5000 PSI.
It depends on the size of the cylinder. Cylinder sizes are based upon the quantity of gas that can be put in them. For example, one of the most common cylinders is an aluminum 80 cylinder - which means it holds 80 cubic feet of gas when pressurized to it's normal working pressure (as described above which is 3000 psi for this one). In reality it will hold a slightly different amount depending on the manufacturer.
Either dry fire it till its empty OR there is a little metal thing on the regulator were u screw it into the gun, if u push it in hard enough air will come out of it. It is coming out at high speed so it will startle you.
You should take a trimix course before you even thinkabout diving with helium as a gas.
If you still want to do it, take a gas blending course from a professional instructor. Otherwise, just ask a dive shop which does Helium fills. Cheaper and easier.
Tanks are usually filled from compressors, which simply pump in new gas until they reached the required pressure. Most dive shops have one or more compressors for this purpose.
Sometimes tanks are directly filled from other tanks (called 'banks'), but that is usually when you need to fill them at a location where you don't have a compressor.
Most recreational SCUBA divers dive using an on demand regulator system. As the diver inhales, the low pressure created in the second stage regulator (the thing nearest the mouth) acts on a diaphragm inside the regulator which provides the diver with air from the tank via the first stage tank valve and a low pressure air hose.
There are 2 answers to this... air or sometimes nitrox is compressed into scuba tanks using multi stage compressors. These use pistons to increase pressure incrementally and then remove the water and filter it in a 'filter stack'.
Oxygen is much more difficult to put into cylinders because it is highly reactive at high pressures. It is either decanted from high pressure oxygen cylinders or pumped from an oxygen cylinder to a higher pressure using a booster pump. You need to ensure that there are no fuels in cylinders like oil from previously being filled with air from a conventional compressor as this can cause a dangerous reaction when the oxygen is added.

How much pressure should my water tank bladder have?
The water pressure depends on the residual air pressure in the tank. Normally it should be between 30 -50-psi. Tank air pressure is important, it should be about 27-29 when water is nearly empty.
How do you pressurize your water system with a well mate pressure tank?
The tank comes with a residual air pressure of about 40 PSI. This can be regulated through the air nipple at top of tank. If you are going to use 30/50 as is common, then set tank air to 28 by adding or letting air out of this nipple while the tank is empty of water. After setting this pressure, adjust the pressure switch to come ON at 2 psi above this , ie 30 PSI. Now when the water level lowers in the bladder the pump will switch ON before the tank is empty. If tank residual pressure is very low on an old tank it is possible that your bladder has holes.
What propels a paintball?
A compressed C02 tank or High Pressure Air tank propels the paintball.
When is A Medical oxygen tank empty?
In general any pressurized gas container is "empty" when the pressure inside is equal to ambient air pressure. There is still gas in the container, but not enough pressure to expell the gas. Medical oxygen tanks should never be allowed to go below 200psi. The tank is considered empty at this point and should be replaced.
When filling a scuba tank from a high pressure reservoir the air goes from a high pressure reservoir to a low pressure reservoir so the air expands into the scuba tank. Shouldnt this cool the tank?
Think on it a bit closer: -- The expansion is happening in the high-pressure reservoir, as some of the air leaves and the rest expands to fill the volume. So you'd expect the supply tank to cool as it empties. -- The compression is happening in the SCUBA tank, where you're continuously stuffing more and more air into the same volume. So you expect the SCUBA tank to warm as it fills.
Can you tell if a cylinder is full or empty depending on its weight?
Yes. Not sure on the exact weights (as it depends on size of tank and pressure of the gas) but you can tell a definite weight difference between an empty and full tank because the compressed air does have a weight
When setting pressure on a bladder tank approx 2 psi below cutin do you do this with the tank full or empty?
You do this with the tank empty. First adjust the air from the nipple usually on top, to 28 psi, then switch on pump to fill tank. Now open 2-3 faucets and watch the gauge very carefully as pressure reduces. Adjust main spring on pressure switch to cut ON at 30-31 psi.
If deep well pressure isfrom 48 to 68 lbswhat should the air tank pressure be set at?
Generally the pressure in the tank air bladder should be 2 psi below the water pressure switch kick in (pump turn on) point. In this example of 48 to 68 Lbs the air bladder pressure should be 46 psi. This pressure should be measured with the tank empty of water, that is to say NO water pressure applied. NEVER over pressurize the air bladder - it would be better to under pressurize if in doubt. Some tank manufacturers may recommend a different PSI differential so check with the tank literature or the manufacturer.
What is a paintball gun that uses a Dye air tank?
Any gun with a High Pressure System (which is basically all of them) can use this tank.
What is the range for air pressure in the tank?
What tank?
If punctured which hose would empty a scuba tank at a faster rate high pressure hose or low pressure hose?
LOW PRESSURE HOSE: Yes, a low pressure hose. A high pressure hose has a very small diameter opening since it is just used to measure pressure and it is not performing any work. A low pressure hose is used to perform work and has a larger diameter opening so air can move through it.
Does an empty tank weigh the same as the tank filled with air?
Something not everyone takes into account is that every molecule has a weight, even the molecules that make up air. It may not be noticeable, but it's definitely present. So if by "empty tank" you mean "a tank containing no molecules", and it were compared to a tank filled with air, or "a tank containing at least one molecule", then you can see that a tank filled with air will weigh more than an empty tank (although the difference may be very very small).
