The object of the utility model is an air curtain housing intended to separate spaces with various temperature parameters.

Numerous solutions related to air curtain housings are known in the field. Such housings are usually formed as massive blocks with approximately cuboid shapes. Their disadvantage lies in the height of the device, which significantly hampers or even renders their installation and use impossible in rooms, where the distance between the door opening threshold and the ceiling is small. Additionally, the shape and looks of the used housings make them items of poor aesthetics, dominating the space surrounding the doors.

The objective of this utility model is to eliminate all the aforementioned disadvantages by developing a new air curtain housing.

The objective of the utility model is an air curtain housing with a body provided with an air inlet and side elements, characterised in that the body is an aerodynamically shaped element elongated towards the front, resembling an airplane wing in its cross- section. The body is closed on both sides with a concave side element provided with a decoration in the form of a scaled body profile and a protrusion comprising of bent, flat surfaces. The air inlet is located on the top surface of the body, along nearly its entire length, with exhaust gas lines located near the inlet. A longitudinal element is located in the bottom part of the body, along its entire length, in which the air outlet and the fixture openings are provided, allowing the housing to be installed in the threshold of the door opening.

The object of this utility model is presented in a drawing, in which Fig. 1, Fig. 3 and Fig. 4 present the housing in axonometric projections, whilst Fig. 2 presents a side view. The air curtain housing according to the model contains a body 3 with an air inlet 1 and an air outlet 7, as well as side elements 4. The body 3 is an aerodynamically shaped element, elongated towards the front, resembling an airplane wing in its cross-section. The body 3 is closed on both sides with a concave side element 4 provided with a decoration 5 in the form of a scaled body profile 3 and a protrusion comprising of bent, flat surfaces. The air inlet 1 is located on the top surface of the body 3, along nearly its entire length, with exhaust gas lines 2 located near the inlet. A longitudinal element 6 is located in the bottom part of the body 7, along its entire length, in which the air outlet 7 and the fixture openings 8 are provided, allowing the housing to be installed in the threshold of the door opening.

The air curtain housing according to the model is significantly shorter than air curtains currently used and available on the market, thus it may be used in lower rooms or in rooms in which the distance between the door opening threshold and the ceiling is small. The air curtain housing according to the model has a modern shape improving the aesthetic appearance of the room thanks to the use of the aerodynamically shaped body element.
