Abstract: A method for actuating a compressor system in order to set a measured operating pressure, which serves as a measure for the operating pressure that the compressor system supplies to a user network at a flow rate demanded by a user network, to a desired operating pressure . The compressor system includes a compressor element with an inlet and an outlet, and where the compressor element is driven by a drive, where the compressor system is provided with a way for throttling the inlet of the compressor element. As long as an operating pressure, selected from the measured operating pressure and the desired operating pressure, is higher than the without the way for throttling the inlet maximum obtainable operating pressure for the compressor system, the inlet is throttled by the way for throttling the inlet for at least a specific percentage greater than zero.

Abstract: An oil separator provided with a housing with an inlet for an oil-gas mixture and which defines a space that is closed off by means of a lid, whereby a screen is provided in the aforementioned space in which a filter element is affixed and a pipe or collector that connects the interior of the filter element to an outlet in the housing for purified gas, whereby the oil separator is provided with a drainage line for the removal of the oil that has been filtered out, wherein the drainage line ensures the removal of the oil that has been filtered out from the underside of the filter element directly to an outlet for oil in the housing.
