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.
