Abstract
A bi-functional filter device for removing liquid from a humid gas flowing through the filter device includes a filter body that includes an axial through-channel that passes lengthwise through the filter's body, through which gas (e.g., humid gas) can flow, and a dehumidifier sleeve that encloses the filter body. The filter body includes a capillary path that may absorb, and thus remove, liquids, for example laterally, radially or spirally (in spiral manner) from the through-channel of the filter body using capillary action, to thus clear the through-channel of the filter body from these liquids. The dehumidifier sleeve may evaporate liquid contained in (and arriving from) the filter body.
