The device has a piezo-element (10) arranged within a housing (1) in a region of a dielectric end cap (3). A frontal exhaust port (2) of the housing is formed by the end cap, and a gas inlet opening (4) is provided at a side of the housing turned away from the port. Alternating voltage is applied to the piezo-element, and the piezo-element is detachably fixed in the region of the end cap by a clipped connection (11) e.g. spring clip. A control board (8) with a phase regulating circuit is provided within the housing such that the piezo-element is controlled and regulated. |
