Diffusers vortex SD-A of a round form are intended for air supply by systems of ventilation and conditioning by the twirled streams from the top zone of rooms.
The vortex mode of a current of stitched air at the exit from a zakruchivatel allows to increase coefficient of ejection of air to a stitched stream in comparison with direct-flow streams and, as a result, to increase intensity of reduction of speed and alignment of temperature in a stream with a room temperature. The product can be used as well for removal of air from rooms.
Diffusers are used as for rooms with a high ceiling (≤10 m, the plants, terminals of the airports, theaters, banquet rooms), and with rather not a low ceiling (≤3,8 m, halls for receptions, halls of hotels). Are suitable for rooms with a high difference of temperature between the arriving air and air indoors.
Diffusers are installed in the top zone of rooms on withdrawal of air ducts at open laying, in podshivny space of a ceiling or on a wall. Installation of diffusers in free space vertically, horizontally or with an inclination towards the served zone is possible.
Installation is carried out by means of a connecting branch pipe which fastens on the self-cutting screws to an air duct or a podshivny ceiling. Tightness of connection with the bringing air duct is provided with rubber consolidation.
Diffusers are manufactured of steel and have a protective powder covering of white color (RAL 9016).
