The air we breathe contains roughly 78% nitrogen, 21 % oxygen, .9% argon and the balance is other gases. The oxygen is separated from the air using PSA Technology. The process centers around a molecular sieve known as Zeolite. The air we breathe contains roughly 78% nitrogen, 21 % oxygen, .9% argon and the balance is other gases. The oxygen is separated from the air using PSA Technology. The process centers around a molecular sieve known as Zeolite. At high pressures the sieve adsorbs or attracts nitrogen, and at low pressures it desorbs or releases nitrogen. Thegenerator consists of two tanks filled with sieve. As high pressure air (about 70 psi) is introduced into the first tank, it passes through the sieve and nitrogen is adsorbed. The remaining oxygen and argon are piped to a buffer or storage tank. Just before the first tank becomes completely saturated with nitrogen, feed air is redirected to the second tank which then repeats the above process. The first tank is the
