Abstract
The present invention relates to a wall ring for receiving in particular an axial fan, comprising an annular body with a flow inlet opening and a flow outlet opening and a central longitudinal axis X-X as well as an annular wall extending between both openings. The annular wall has a cavity which is enclosed by an outer wall and an inner wall, in which an electrical heating element may be secured at least over a partial area of the periphery of the annular wall. The annular body consists of at least two partial bodies which are formed by a division of the annular body in a separating plane that extends perpendicular to its longitudinal axis and are detachably connected to one another.
