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.

Model 530 single deflection louvered return air grilles have fixed blades on 3/4” centers, 45 degree blades parallel to the long dimension, B12 white baked enamel finish, and face screw fastening on all sizes except frame with no screw holes for lay-in application on the 22" x 6", 22" x 10", 22" x 22", 46" X 22". Optional damper (loose) model VCS3 comes complete with screwdriver operated blade adjustment with patented detent mechanism to assure damper position is maintained.

The Square Plaque Diffuser (Model SPD) has a flush appearance, making it ideal for architecturally-conscience commercial spaces, and provides industry-leading low pressure drop and sound generation with a 360° radial, horizontal air pattern for rapid mixing and optimal thermal comfort. The one-piece, aerodynamically optimized backpan maintains the horizontal air pattern even at low air volumes, making it a great choice for high turndown VAV applications. This versatile diffuser is easy to maintain, with little to no ceiling smudging and a tool-free removable face for quick access to dampers, accessories, and ductwork. This product comes in the standard B12 white finish.
