Abstract
A discharge control device for a filter system and a filter system for filtering a media flow of a first and a second medium is provided with a collecting chamber that collects the second medium separated from the media flow. A sensor arrangement with a first sensor unit, a second sensor unit, a first shut-off valve having a closure body, and a second shut-off valve is provided. The first sensor unit is operatively connected to the first shut-off valve. The first sensor unit has a float that purely mechanically actuates the closure body of the first shut-off valve. The second shut-off valve is arranged in series in flow communication with the first shut-off valve. The second shut-off valve has an electromagnetically actuatable valve controlled by the second sensor unit as a function of a fill level of second medium in the collecting chamber.
