The air through passage device is for installation in a wall or ceiling aperture of a room. From a basic surface component (20) on the central rear side, a connecting support (24) extends. The basic surface component in its central area (26) has at least one throughflow hole (28) which is surrounded by the connecting support. From the side edges (30) of the connecting support front side distance holder, components (32) extend forwards. The spaced apart distance holder components are provided for the releasable fixture of a cover component (40) by magnetic force. The cover component is formed with viewing holes (54), arranged in a grid pattern.</p> |
