Abstract
An oxygen concentrator system that includes or can be expanded to include more than one compressor is provided. The system utilizes a controller that is adapted to selectively activate or deactivate one or more of the compressors to optimize system performance and efficiency. Multiple compressors can be selected to operate at the same time, thereby enabling the system to operate at a higher peak pressure, increase the recovery of the PSA cycle, and expand the product rate. The additional compressors can also be removed when not in use so as to reduce weight of the system. In some implementations, the system housing reserves a certain amount of space for accommodating additional compressors and related components, which can be added to the system as after market parts. In other implementations, the additional compressor can be located external to the system.
