ABSTRACT:
A test device (10) for filter systems, including a pneumatic unit (12), a control unit (14) for controlling the pneumatic unit (12), and a data processing unit (16), in which the pneumatic unit (12) is separated from the data processing unit (16) and the control unit (14) by a separating device (18) which substantially shields the pneumatic unit (12) against heat generated in the data processing unit (16) and the control unit (14).
