Multi functional filter

摘要

In a filter, a rotatable connection flange with two kidney-shaped openings and a diametral web between the openings is located between the top part and bottom part of the filter. Rotating the connection flange allows the direction in which a gas flows through the filter element located in the filter housing to be reversed. In this way, the filter can be operated as a coalescence filter or as a dust filter by simply rotating the connection flange.
