Answer
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.
Take Care
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.
