Oxygen boosters require some design features which may not be necessary in boosters for less reactive gases. It is necessary to ensure that drive air, which may not be sufficiently clean for safe contact with high pressure oxygen, cannot leak past the seals into the booster cylinder, or high pressure oxygen can not leak ito the drive cylinder.
An oxygen concentrator takes in air and removes nitrogen from it, leaving an oxygen-enriched gas for use by people requiring medical oxygen due to low oxygen levels in their blood.
