Abstract

A heater side channel blower includes a blower housing (12) with a bottom wall (14) and a circumferential wall (16), that enclose a first flow chamber in a housing interior (18). A ring-shaped delivery duct (22), open towards an outer side of the blower housing (12), is provided at the bottom wall (14). A flow medium inlet (50), for the entry of medium to be delivered into the housing interior (18), is open towards the first flow chamber. A second flow chamber (42) is provided in the housing interior (18). A flow medium outlet (52), for the discharge of medium to be delivered from the housing interior (18), is open towards the delivery duct (22) to the second flow chamber (42). The first flow chamber is separated from the second flow chamber (42) by at least one chamber separation element (60, 62) that is permeable to medium to be delivered.
