Abstract
A device (1) is provided for ventilation and integrity testing of a filter unit (2) that can be supplied with pressure. The filter unit (2) has a filter element (9) arranged in a housing (6) between an inlet (7) and an outlet (8). The housing (6) can be ventilated by an air filter (3) connected to the housing interior (12). A filter valve (4) is arranged upstream of the air filter (3) facing the housing interior (12) and connects the air filter (3) to the housing interior (12). The air filter (3) can be connected on its side facing away from the housing interior (12) to a test line (14) for supplying pressure. An inlet valve (5) is arranged upstream of the inlet (7) and connects an inlet line (10) to the housing interior (12).
