Diffusers are intended for use in stitched and exhaust systems of ventilation and conditioning in internal rooms of residential and public buildings. Diffusers happen adjustable and unregulated. They represent airdistributing elements with smooth regulation of a consumption of air which is carried out by means of rotation of the dish-shaped valve and help to distribute evenly given air on all room space, and also can be used for individual regulation of an air stream. So diffusers reduce air speed at its giving from stitched flexible air ducts and, on the contrary, increase the speed of exhaust air at its receipt in an exhaust air duct.
Diffusers are manufactured of high-quality ABS plastic. For convenience of installation diffusers are supplied with spring fastening and a flange.
