    Oxygen Concentrator typically usepressure swing adsorption(PSA) technology and are used very widely for oxygen provision in healthcare applications, especially where liquid or pressurized oxygen is too dangerous or inconvenient, such as in homes or in portable clinics. For other purposes there are also concentrators based onmembrane technology.

    An oxygen concentrator takes in air and purifies it for use by people requiring medical oxygen due to low oxygen levels in their blood.[1]Oxygen concentrators are also used to provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators oroxygen generation plants. Oxygen concentrators utilize amolecular sieveto adsorb gases and operate on the principle ofrapid pressure swing adsorptionof atmosphericnitrogenontozeoliteminerals and then venting the nitrogen. This type of adsorption system is therefore functionally a nitrogen scrubber leaving the other atmospheric gases to pass through. This leaves oxygen as the primary gas remaining. PSA technology is a reliable and economical technique for small to mid-scale oxygen generation, with cryogenic separation more suitable at higher volumes and external delivery generally more suitable for small volumes.[2]

    At high pressure, the porous zeoliteadsorbslarge quantities of nitrogen, due to its large surface area and chemical character. After the oxygen and other free components are collected the pressure drops which allows nitrogen to desorb.
