Abstract: A diagonal fan has an electric motor, housing, and diagonal impeller, which is accommodated within the housing, can be driven via the electric motor, and generates a diagonal flow during operation that is deflected in an axial flow direction by an inner wall of the housing. Outlet guide vane device with a plurality of guide vanes distributed in the circumferential direction is arranged adjacently to the diagonal impeller when viewed in the axial flow direction, and homogenizes airflow generated by the diagonal impeller. vanes have a radial extension from a hub region of the outlet guide vane device to the housing. An imaginary extension in the outflow angle of the diagonal impeller strikes the inner wall of the housing at an axial distance K from the diagonal impeller. Outlet guide vane device is arranged at axial distance H to diagonal impeller where 0.75?K/H?1.25.

Abstract: A fan includes a fan housing and a motor accommodated therein. The motor has a stator and a rotor, which is connected to a fan wheel. The fan housing consists of at least a housing upper part and a housing lower part. The housing upper part has an axial opening on the axial inner face of which facing the housing lower part the stator is arranged. On the axial outer face of the axial opening at least electronics are arranged.

Abstract: A fan, in particular an axial fan, comprising a support element with a wall ring and an electric fan motor which is mounted in the wall ring and comprises a fan rotor. The wall ring has on its outer periphery a hinge consisting of a first hinge part that is connected to the wall ring and a second hinge part that can be pivoted about a hinge axis relative to the first hinge part, wherein the second hinge part is designed as a terminal box for receiving electrical connectors. The invention further relates to a support element for such a fan.

Abstract: A blower (1) with a blower housing (2), a blower wheel (4) positioned so as to rotate inside a blower housing (2), an electric motor (6) for the rotational drive of the blower wheel (4), as well as with a saucer-shaped attachment housing (8) positioned externally on the blower housing (2). The attachment housing (8) contains motor-control electronics (10) and exhibits in its connection area facing the blower housing (2) a metallic cover element (14) covering the motor control electronics (10) and protects against an electromagnetic radiation from the electric motor (6).

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.

Abstract: Flat illuminating display device with light emitting means to illuminate a film for display of an image applied to a display area, wherein the light emitting means are embodied as at least one light coupling unit arranged laterally at a translucent film thus forming a light duct, wherein the light such fed into the adjacent edge area into the film is reflected by a reflective layer, which is applied on at least one side, to homogeneously spread within the film, wherein a reflection screen to obtain a light emission is provided opposite of the display area to create said display area.

Abstract: A fan unit (1), to be attached to a filter frame (40) of a filter fan, consisting of a housing with a cylindrical housing rim, an inlet opening (20), an outflow opening (7) and at least one protective grid which covers one of both of the openings, and one fan (4) attached to the housing via a motor mount (14) which conveys the air in at least the axial direction. The design enabling the manufacture of a more compact fan unit in an easier and more cost-effective manner, which provides high efficiency and can be installed as a suction as well as a blowing fan unit in the filter fan, and is easy to dismount for the maintenance of the filter fan.

Abstract: A diagonal fan has a diagonal fan impeller (1) which is fastened to a rotor (2) of an external rotor motor (3) and which is arranged between a front plate (5), which has an in particular central inflow opening (6), and a motor bracket (4). The motor bracket (4) is connected to the front plate (5) via a plurality of peripherally arranged spacers (21). Here, the front plate (5) and the motor bracket (4) are formed as plastic or metal injection molded parts. The spacers (21) are formed, as plastic or metal injection parts, in one piece with the front plate (5) or with the motor bracket (4).
