a housing including an inner side;
an electrical body attached to the housing and extending at least partially into the housing and adapted to connect a power source to an electrical element; and
an annular element defining an aperture, wherein the electrical body is disposed in the aperture, and wherein the annular element is axially moveable relative to the electrical body between one or more axial positions along a central axis of the electrical body,
wherein the housing is provided with a passage for allowing air to flow between an end of the housing to be turned towards a room of the building and an end of the housing to be turned towards the air duct and for allowing air to flow in the space between the inner side of the housing and an outer side of the electrical body, wherein the annular element is axially moveable between the one or more axial positions to change a flow property of the air through the passage.
