When you need Oxygen at higher pressure (>4 bar after utilizing the compressor) the VPSA Oxygen Generator would be a mindful choice.
The Oxygen compressor in the VPSA, along with the buffer vessel, and the vacuum pump helps the VPSA Oxy-Generator to provide gas from as low as 0.3 to >4 bar pressure.
Finally, the remaining Nitrogen Gas is released back into the environment through the silencer and the Oxygen can be utilized directly from the buffer vessel for continuous feeding or use of the gas.
Installing the VPSA Oxy-Generator without a doubt stands as a radical choice if you haven’t installed it already.
