Abstract

"COMPRESSOR CENTRìFUGO". é fornecido um compressor compacto e eficiente, baseado na utilização de tecnologia de rolamentos magnéticos, que pode funcionar em alta velocidade e compreende um sistema de controle confiável. o compressor da presente invenção faz uso de dois compressores separados montados sobre um motor único em comum, compartilhando assim um acionamento único. O equilíbrio do solavanco em altas rpm é melhorado pela utilização de um par de rolamentos eletromagnéticos.
