Abstract: A liquid separation device for a compressor system has at least one coarse separation unit, which has at least one coarse separator and a liquid removal device; at least one fine separation unit, which has at least one fine separator and a liquid removal device; and at least one liquid removal channel which leads off a liquid from the respective liquid removal devices, wherein the at least one liquid removal channel is formed in the liquid separation device.

Abstract: A compressor-oil-receiving apparatus for a compressor system filled with a compressor oil for transfer into the compressor system. The apparatus includes a housing which forms a receiving volume for the compressor oil, and an oil filler neck with a filling opening on a side, which is directed away from the receiving volume and with an outlet opening on a side which is directed toward the receiving volume, wherein the oil filler neck forms a housing opening for filling of the receiving volume with the compressor oil, and the outlet opening is arranged such that, through filling of the receiving volume, an air volume enclosed by the housing, and the compressor oil that has been introduced is formed in the receiving volume.
