Ceiling diffusers

Back to Diffusion

The KZ series units are circular high induction diffusers with variable geometry. These diffusers consist of an outer casing, known as a 'bell', and six swivelling blades in a radial arrangement. The angle of inclination of the blades is adjusted synchronously by means of a mechanism with manual override or with a servomotor (optional).
