InebesondBrB bei FeinfiÜBrn ist bb zu deren FunktiansfShigkeit erforderlich, diese dicht in den umgebenden Luftkanal einzusetzen.

In the case of the relatively thin fine filters, it is therefore preferred to use a clamping device for the purpose of framing them. In the case of a fine filter according to the invention with a relatively elastic, coarse fleece layer that is several times thicker, it is possible to achieve a tight seal in a simple U-profile frame h if (the distance between the legs i * a, b is somewhat narrower than

Somit kann wsdBr beim Gebrauch noch beim Einbau eine Undichtigkeit zwischen Filter und Rahmen entstehen, und der atetige Übergang vom Rahmen in den durch das Grobvlies elastisch gestützten Bereich verhindBrt das Entstehen von großen Spannungen und Bomit vor RisBen im Feinfilter.Thus, wsdBr can still cause a leak between the filter and the frame during installation, and the ongoing transition from the frame to the prevents the elastically supported area by the coarse fleece the emergence of large tensions and cracks in the fine filter.
Eine spezielle Ausführung das Filters ist die Gestaltung als StaubbButBl5,dBr mit dem ausgerüsteten Grobvies 1 umgeben ist. In Fig. 3 iBt ein solches Filter dargßstBllt, bei dem der Beutel nur teilweise, nämlich auf der Seite, auf der die Luft in das Filter einströmt; mit dem GrobvlieE1 umgebBn ist.

FIG. 3 shows such a filter in which the bag is only partially, namely on the side on which the air flows into the filter; is surrounded by the coarse fleece 1 . This arrangement has the advantage that with an increasing degree of filling (J dBB dust bag, the air flows more intensely through the coarse fleece, which would compensate for the required decrease in adsorbent in the way that an equal increase in the release of the absorbent is achieved over the service life of the dust bag.
