The invention relates to disinfectants and can be used to enhance the effectiveness of bactericidal disinfecting air using ultraviolet radiation.A device for disinfecting air comprising a housing with inlet and outlet windows which is formed by the irradiation chamber having longitudinally arranged mercury discharge lamps of low pressure, provided with inlet and outlet labyrinth screens and installed power supply unit connected electrically to the control and display unit, wherein in input window filter is placed, and the exit window, respectively, placed fan. The body is made splittable in a thin-walled box-shaped body of two connected around the perimeter of identical trough-shaped half-shells, comprising a base and side walls, on the basis of one half shell, which is structurally anchored discharge mercury lamps, and the other half shell is a faceplate, cover, by irradiation chamber the base of each half shell are attached symmetrically arranged with the central transverse stiffener plate at the edges, directed towards the window, and from the window to the bottom of each first half shell and the side walls are attached oppositely on the same plane on two lateral transverse plate stiffener at the edges, directed towards the irradiation chamber, the distance between which is smaller than the width of the central transverse plates which is less than the width of the - cross-housing size, and the central transverse plate and side transverse when connecting plate into the housing half-shells form a labyrinth screens with solid cross labyrinth baffles. In this case, the inside of the housing is provided with a reflective screen. The power supply unit is situated in the middle zone of the irradiation chamber with the gap between the bottom bearing half shell and mercury gas discharge lamps.Полезная модель относится к средствам дезинфекции и может быть использована для повышения эффективности бактерицидного обеззараживания воздуха с использованием ультрафиолетового излу
