Ibhleyidi ye-injini yomoya (ivili) lelinye lamacandelo angundoqo wesixhobo samandla omoya, ebalwa malunga ne-15% - 20% yexabiso lilonke lesixhobo.Uyilo lwayo luya kuchaphazela ngokuthe ngqo ukusebenza kunye neenzuzo zezixhobo.
Iiblade zeefeni ziqhele ukusetyenziswa kwiifeni, izivutheli zeinjini yomoya, izivutheli zengcambu kunye neecompressors zeinjini.Zahlulwe zibe ziindidi ezisibhozo: i-centrifugal compressors, i-axial-flow compressors, iicompressor eziphindaphindayo, ii-centrifugal blowers, ii-root blowers, iifeni ze-centrifugal, iifeni ze-axial-flow kunye nezivutheli zenu.
