Abstract: An oil separator for separating entrained oil from a gas stream, the separator being arranged on a housing wall which divides a housing interior from a housing exterior. A support tube, which is arranged inside an outer casing and carries a filter element on its outer circumference through which gas can flow radially. The support tube is closed at its upper axial end face and communicates at its lower axial end face with the housing interior. An impingement separator is arranged in the vicinity of the lower axial end face of the support tube. The outer casing is closed at its bottom relative to the housing in a sealed manner.

Abstract: A filter element (15), especially suitable for separating entrained oil from an air stream, having a drainage device (23) including a drainage tube (22) which is connected to an upper end disk (16) of the filter element (15) by a connector (24) which may include preferably releasable clip hooks (25). The resulting filter element with a drainage device is easy and economical to manufacture, and may have a modular construction in which the connector (24) and the drainage tube (22) are separate components so that the length of the drainage tube can be optimally matched to various filter dimensions.
