Development of Oxygen Generator for Vehicle with Two Head Vaccum Pump

An oxyge generator, which is applied to a particular space such as automobile, must consider compactness and lightweight as well as problems caused by noise, vibration and heat dissipation. For these matters, a BLDC motor was adopted to reduce heat while a bed using synthetic zeolite NaX made it possible to generate high-density oxygen with relatively small size. Moreover, owing to the characteristic of synthetic zeolite Nax, a two-head vacuum pump was designed to desorb nitrogen without additional pump unit.
