The invention relates to the field of construction, and more particularly to tubular roof-mounted ventilation devices, and can be used in ventilation systems in buildings and structures and primarily in ventilation systems for pitched roofs. The technical result is achieved in a device which consists of a passthrough element, a tubular element and a deflector and which is characterized in that the passthrough element is in the form of a flat square sheet with a hemispherical boss in the middle, said boss being provided with a shaped opening which, when rotated about its axis by 90 degrees relative to the tubular element, makes it possible to use the device on roofs with various angles of pitch from 0 to 55 degrees, wherein the tubular element is conical with an angle of 4 degrees at the vertex of the cone, and the lower part of the tubular element is a skirt configured in the form of a hemisphere which is truncated on one side, while in the upper part of the tubular element there is a flat mounting ring with cutouts and projections, said mounting ring engaging with slot-like cutouts in mounting projections situated on the inside surface of the deflector, wherein the mounting ring is fastened when the deflector is placed as far as it will go on the tubular element and rotated by 30 degrees, the projections on the mounting ring being fastened in the slot-like cutouts in the projections on the deflector. |
