Principle
The composition of air (78% Nitrogen, 21% Oxygen and 1% other gases like Carbon Dioxide, Argon, etc.) clearly shows that air is mainly comprised of two gases Nitrogen and Oxygen [together 99%] If Nitrogen is removed from air, the primary gas remaining would be Oxygen with purity of about 90-95%. An Oxygen Concentrator uses this idea with the basic principle of Pressure Swing Adsorption (PSA) to deliver 90% pure oxygen.
Ambient air (room air) passing through a series of filters is drawn into the machine by a Oil Free Piston Type compressor which is feed into (A) Molecular sieve bed and all the Nitrogen is adsorbed and Oxygen Passes through to attain a concentration of up to 90%. Just before (A) molecular sieve bed gets saturated, the Switch Valve comes into action and output of the air compressor is immediately switched to (B) sieve bed i.e. the compressor starts compressing air to the (B) molecular sieve.
The Nitrogen that was trapped in the 1st sieve bed is flushed Out. The switch valve again switches the output of air compressor back to the (A) sieve bed as soon as the (B) sieve bed approaches saturation. This process keeps on repeating to ensure continuous flow of Oxygen. This process of switching the sieve beds is known as Pressure Swing Adsorption (PSA). The output of Oxygen is then controlled using a flowmeter where the flow can be set manually in Litres Per Minute (LPM)
