Abstract: An air passage device, in particular a filter fan or outlet filter for installation in a mounting opening in a wall or in a housing of a switch cabinet, which is essentially formed by a ventilation grating and a main housing, and a filter mat is insertable between the ventilation grating and the main housing, the ventilation grating being situated on the main housing using an articulated connection, the ventilation grating having joint pins to form the articulated connection, which may each be guided in joint pin guide structures introduced into the main housing, the joint pin guide structures each connecting at least one closure position, one folded-out catch position, and one removal position to one another. An air passage device is thus provided which, based on a simple construction, allows high flexibility in regard to the operation of the ventilation grating and the filter mat.

Abstract: The filter fan with a basic casing with a frame which is provided with quick fixing devices in form of spring-elastic preferably wing-type brackets is configured in such a manner that the frame is configured continuously closed all around its periphery and the brackets configured as plate-shaped blanks are molded on the frame, brackets which are provided with a number of slits for constituting spring-elastic snap-in tongues.

Abstract: An air passage device for installation into a mounting opening (50) in a wall (51) for components generating waste heat, such as a switch box, includes a base housing (21; 221) with a fan support (25) and a design cover (80; 280), wherein the design cover (80; 280) has on an air inlet side a covering device (100) constructed as a fan grid (10; 210) with sheet elements (90, 90?; 290, 290?).

Abstract: A filter fan includes a basic housing with a frame, wherein the frame is equipped with a quick fastening device in the form of spring-elastic clips. In order to prevent air and/or moisture from penetrating into a housing, the frame extends continuously and without openings around a circumference. The clips are molded onto the frame.

Abstract: In a covering device (100) for covering the front area of a device for the passage of air (200) for fitting in an opening in a wall of a casing, in particular of a casing of waste heat producing components, of an electronic cupboard or of a switch cupboard and for the filter mat (60) of the device for the passage of air, whereby the covering device comprises a design cover (80) covering the filter mat (60) with a number of inclined lamellar elements (90), each lamellar element (90) has in its upper area (90a) a section with a hook-type configuration (95) orientated against the air admission.

Abstract: The switch cupboard for receiving electrical and electronical components and switching elements which is subject to a rotation and which has at least one cooling device (30) with a cold emitting device part (31) placed in its inner space (23) and with a heat emitting device part (32) which is situated outside the switch cupboard (20) and which is placed for example in the tower head (11) of a wind power station is configured in such a manner that a condensate ring (41) is placed as a shell-shaped collecting trough (40) in the area of the cold side (31a) of the cooling device (30) which is placed in a wall (22) of the switch cupboard (20), cold side which is situated in the inner space (23) of the switch cupboard (20), whereby the inner space (42) is connected with a hose (50) guided out of the inner space (23) of the switch cupboard (20) which is configured as a spiral hose (50a) in the area of the warm side (32a) of the cooling device (30) situated outside the switch cupboard (20), whereby the spirally confi

Abstract: An airflow unit, especially a filter fan or discharge filter with or without a tan for installation in an installation opening in a wall, especially a housing for components that produce waste heat, includes a ventilation grating composed of a frame holding a filter medium, a support member with a frame having a peripheral wall surface which expands outwardly, wherein the support member is provided with airflow openings and with water-diverting wings or rib formations. A shielding grating is inserted in the support member on a side facing away from the ventilation grating. An IP seal is foamed onto the support member for protection against splash water and spray water. All components of the airflow unit are held together by clamp or screw connections. The airflow unit is placed on the outer wall surface of the wall of the housing and is preferably detachably connected with the housing wall.

Abstract: The air conditioning system for cupboards for receiving control and automation systems as well as for the network technique, in particular for switch cupboards with a cooling device, is characterized in that warm air (WL) is sucked from the inside (22) of the switch cupboard (20) by means of a fan (31) and is supplied to one or at least two evaporators (35, 135), preferably placed in the surface plane of the fan (31), whereby cold air (KL) is conducted into the inside (22) of the switch cupboard (20), whereby a condenser (45) is placed below the evaporators (35, 135) in such a way that the evaporators (35, 135) come to rest with a section or with their front areas (35a, 135a) above the condenser (45) so that condensate delivered by the evaporators (35, 135) drops onto the condenser (45) and evaporates or volatilizes, whereby ambient air (UL) is delivered to the condenser (45), whereby the cold air delivery sections to the inside (22) of the switch cupboard (20) are constant in their lengths or changeable in l
