Our VPSA oxygen generator is able to generate oxygen with purity between 90% and 95%. It is mainly composed of air blower, vacuum bump, switching valve and oxygen buffer tank. The production cost of using this VPSA oxygen generator will decrease as the production volume increases, which makes it suitable for applications like medium and large industrial systems where continuous supply of high purity oxygen is required. For this oxygen generator, we can delivery as turnkey project, as well as send professional technicians for on-site measurement, layout, preparation of drawings, and carry out equipment production and delivery after confirmation.
