Adjustable circular diffusers SagiCofim Technical features The CC 600 series diffusers have a sophisticated design. The adjustable front plate, and the absence of concentric elements make them particularly suitable for modern tertiary facilities. These diffusers are suitable for either ceiling and exposed ductwork installation. The vertical position of the front plate can be adjusted in five different positions to deflect the air stream horizontally (Coanda effect) or vertically during the heating phase. The diffusers include four removable components: outer cone, connection adapter, adjustable front plate, telescopic damper fitted on the adapter (available upon request).
