Abstract: An air purification device with air guidance, including a housing, including an air intake region, formed in an inlet plenum, for drawing dirty air into the housing, and an air discharge region, formed in an outlet plenum, for discharging filtered air from the housing, a fan impeller of a radial ventilator that is rotatable about a ventilator rotational axis and an air filter for filtering the air drawn in through the air intake region being situated in the housing, the main nozzle air flow formed downstream from the air filter being deflected in the direction of the fan impeller at a main nozzle situated in the housing, upstream from the fan impeller. The main nozzle air flow is split by an auxiliary nozzle that is situated upstream from the main nozzle, and the auxiliary nozzle supplies an auxiliary nozzle air flow into the inner intake region of the fan impeller.

Abstract: An air purifier with mount for a vehicle, wherein the air purifier consists of a fan in a portable housing, which has at least one air intake region for sucking air into the housing and at least one air discharge region for blowing the air out of the housing, wherein a cleaned discharge air flow flows out into the passenger compartment, wherein the mount consists of an adapter plate that can be detachably fixed in different positions in the interior of the motor vehicle, and wherein the air purifier is rotatably mounted in the adapter plate.

Abstract: A personalized air cleaning device having a housing which has at least one air intake region for sucking air into the housing and at least one air blow-out region for blowing the air out of the housing, a cleaned blow-out air stream being directed towards the body, and in particular against the face of a user, the housing of the air cleaning device being of approximately disc-shaped round or oval or polygonal design, and wherein the air intake region and the air outlet region are arranged in the same plane on the circumference of the housing.

Abstract: An air purifier (1) with mount for a vehicle, wherein the air purifier (1) consists of a fan in a portable housing (2, 4, 5), which has at least one air intake region (45) for sucking air into the housing (2, 4, 5) and at least one air discharge region (50) for blowing the air out of the housing (2, 4, 5), wherein a cleaned discharge air flow (51) flows out into the passenger compartment, wherein the mount consists of an adapter plate (6) that can be detachably fixed in different positions in the interior of the motor vehicle, and wherein the air purifier (1) is rotatably mounted in the adapter plate (6).

Abstract: Personalized air cleaning device (1) having a housing (2) which has at least one air intake region (3) for sucking air into the housing (2) and at least one air blow-out region (4) for blowing the air out of the housing (2), a cleaned blow-out air stream (32) being directed towards the body, and in particular against the face of a user, the housing (2) of the air cleaning device (1) being of approximately disc-shaped round or oval or polygonal design, and in that the air intake region (3) and the air outlet region (4) are arranged in the same plane (39) on the circumference of the housing (2).

Abstract: The present invention may be used for framing a fluid flow filter pack. A first frame member may have a first border element with an open portion. The first border element may have four first side walls bendable along a line parallel to a peripheral edge of each of the first side walls. A second frame member may have a second border element with an open portion. The second border element may have four side walls bendable along a bend line parallel to an outer edge of each side wall. Each side wall of the second frame member may have a sealing flap bendable along the outer edge. The second frame member may be positioned on the first frame member with each side wall overlapping and attached to one of the first frame member side walls. The sealing flap may be bent to be adjacent to the second frame member side walls.

Abstract: A filter unit with a filter element receptacle and a filter element, where the filter element having a filter element box in which is inserted a filter pack or a filter medium. The filter element box has a filter element cover on which there is a peripheral projection which engages in a corresponding taper on the filter element box. In addition, the filter element can be inserted into the filter element receptacle which engages with a sealing effect in at least one corresponding packing groove of the filter element cover or box with at least one sealing web molded onto it.

Abstract: The invention relates to an air purification apparatus substantially comprising a suction part, a ventilator housing with one or several ventilators and one or more air filters disposed before or after the ventilator, wherein a housing implemented with a base comprises modular function parts disposed tower-like one above the other, one engaging the other in sealing fit and readily detachable one from the other and at least one pivoted lever disposed pivotably on the lateral portion of the housing by means of a pivot receptor in the direction of the arrow and extending over all parts of the housing from the outside and clamping them together. The air purification apparatus additionally fastenable on the ceiling is usable in particular as spot suction, as ventilation or overpressure or as clean-air purification apparatus.
