We provide all kinds of PSA oxygen and nitrogen making machines, which can be installed on site, and are suitable for all industrial oxygen and nitrogen applications.Based on the mature PSA technology, two sets of adsorption towers, one tower for adsorption, one tower for desorption and one tower for circulation, are adopted to provide continuous and reliable supply of oxygen and nitrogen.

VPSA oxygen production equipment mainly consists of a blower, vacuum pump, oxygen adsorption tower, balance tank, switching valve, and PLC control system. The raw material air is pressurized by the blower, cooled by the cooler, adsorbed by the adsorption tower, and desorbed by vacuum pump to finally separate the oxygen from the raw air.
