A filter system for a containment through which a gas flows, comprising at least one filter unit. First docking means on the filter unit removably connect the filter unit to a receiving port of the containment. The filter unit further has a closure element having an adjusting mechanism to block and open an entry into the filter unit. A drive unit can be connected to the adjusting mechanism. The connection between the adjusting mechanism and the drive unit is preferably dockable. The drive unit has a motor preferably in the form of an electric motor with a pinion or a gear. The transmission ratio of the motor to the transmission part is greater than 1:20, preferably greater than 1:30, for example 1:33. A control unit can switch and monitor the position of a plurality of closure elements according to a program. The adjusting mechanism can also be actuated manually.

To obtain an improved possibility of establishing the causes of failure in linear drive devices with an electric drive, operational data logging means shall be provided for logging data in connection with operational loads and/or an operating state of the electric drive, which occur over a certain period of time, wherein the operational data logging means can be connected to the power connection means for data logging. Means for storing data, which are based on a plurality of measurements of the same measured variable, which measurements are performed one after another, make it possible to log and evaluate data over a long period of time, preferably during the entire service life of the linear drive device. The measurements are carried out during the use of the linear drive device () during which it is in a loaded state.
