SCD - Square Cone Diffuser
SCD, ASCD, SCDA, ASCDA, SCD-FR, SCDA-FROverview
The Square Cone Diffuser (SCD) features a highly engineered, aerodynamic backpan and cone assembly that creates a horizontal 360° radial air pattern. The SCD promotes rapid mixing, temperature equalization, and velocity reduction with industry-leading low pressure drop and sound generation. Ideal for VAV applications with high turndown rates, the SCD maintains a consistent, stable air pattern even as air volume is reduced, minimizing dumping and drafts.
