A method of testing a system including a plurality of modules, each of which in use, produces from an air supply, a product gas which is one of oxygen gas and oxygen enriched gas, the method including providing to an inlet to at least one of the modules, when the module is not in use, a restricted air supply, and at an outlet of the module, sensing at least one of the oxygen concentration and product gas pressure, and analysing the sensed oxygen concentration and/or product gas pressure during a test period to determine the potential performance of the module in use.
