Zusammenfassung:	The invention refers to a method and device for ventilating a device for electron beam irradiation of a web (W), the method comprising the steps of: providing a first chamber ( 107 ) comprising a web inlet opening ( 115 ) and a web outlet opening ( 115 ) and a web outlet opening ( 121 ), providing a second chamber ( 111 ) extending inside the first chamber ( 107 ), the second chamber ( 111 ) comprising a a web inlet opening ( 114 ), a web outlet opening ( 112 ), and an electron exit surface ( 21 ) through which electrons are adapted to be emitted into the second chamber ( 111 ), passing the web (W) through the second chamber ( 111 ), and creating a flow of a gaseous fluid through both the first and second chambers ( 107, 111 ) in a direction opposite the direction of travel of the web (W) by supplying said fluid into the web outlet opening ( 121 ) of the first chamber ( 107 ) and providing at least one outlet ( 113 ).
