The Square Cone Diffuser (Model 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. The Square Cone Diffuser, or SCD, is ideal for use in ceiling applications and is compatible with most standard ceiling styles. This product comes in the standard B12 white finish.
