Abstract
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.
