Air/oil separators from MANN+HUMMEL impress with efficient oil separation in compressors and vacuum pumps. Within the compression process of oil-cooled compressors, oil is used to seal, lubricate and cool the air. The residual oil contained in the compressed air is almost completely separated by an air/oil separator within the pressure vessel or a spin-on separator outside of the pressure vessel through application of the coalescence effect. The cleaned air is then available for the compressed air network. The separated oil is conveyed through overpressure back to the oil circuit. Hence, air/oil separators significantly reduce oil consumption and as a result also lower the operating costs of compressors and vacuum pumps. Our market products offer solutions for a wide range of applications.
