Abstract
A compressor generates compressed air. Iron powder is provided in a deoxidizing chamber. The compressed air is supplied to the deoxidizing chamber such that the compressed air reacts with the iron powder to form iron oxide, so that oxygen contained in the compressed air is reduced to obtain remained nitrogen gas.
Claims21
