Round, adjustable ceiling diffuser with removable core and safety chain for all sizes greater than 12". The Round Cone Diffuser (RCD) combines the visual appeal of a round cone design with maximum air diffusion efficiency. The RCD offers adjustable airflow with a variety of different adjustment methods allowing for the perfect balance between performance and economy. Ideally suited to exposed duct applications, Round Cone Diffusers provide a strong horizontal pattern, even without a ceiling present. Easily adjustable to provide both horizontal and vertical air patterns, performance of the RCD can be maximized for both heating, and cooling applications. This product comes in the standard B12 white finish. Damper optional (view related products).

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.

The Square Cone Diffuser with adjustable pattern (Model SCDA) provides either a horizontal or vertical air pattern. The pattern controllers allow for field adjustment of the diffuser to optimize comfort in the occupied zone. The Square Cone Diffuser 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 SMDSR is a square directional ceiling diffuser with removable core and square to round adapter. The SMDSR features large square and rectangular inlets for reduced inlet velocity, resulting in low sound and pressure drop even at high airflows. The modular louvered face diffuser is highly configurable with multiple core styles, airflow patterns, and optional features to tailor this product to specific applications. This product comes in the standard B12 white finish.

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.

The VCR8E round butterfly style damper provides airflow adjustment at the diffuser neck. Volume control blades move simultaneously in opposite directions, to provide superior metering and control with minimal disturbance of the air pattern. For optimized sound performance it is recommended to match an upstream duct branch damper for large volume control with a damper at the diffuser for fine tuning.
