Square directional surface mount ceiling diffuser with removable core, opposed blade volume damper, and 4-way discharge pattern. The SMD is well suited to applications that require large volumes of airflow at low sound and pressure drop. Concentrated airflow is discharged from each active side of the diffuser, resulting in longer throws that are ideal for high ceiling applications. This product comes in the standard B12 white finish.
The Perforated Face Return Module (PFRF) is an economical, high capacity return outlet. These perforated ceiling panels are used as non-ducted return outlets for T-bar lay-in ceilings. With no frame, free area is maximized to provide low noise and pressure drop. The PFRF perforated face return module is ideally suited to t-bar open ceiling return applications. This product comes in the standard B12 white finish.
The perforated supply diffuser with face mounted pattern controllers (Model PDF) is extremely versatile, available in a wide variety of sizes with a full selection of frame and mounting styles. The face mounted pattern controllers provide an adjustable horizontal air pattern with a strong Coanda effect against the ceiling. Louvered air pattern deflectors are spring clip mounted on the back of the diffuser face. Simply pull down and rotate pattern deflectors for easy field adjustment of the discharge pattern (4, 3, 2 or 1-way). This product comes in the standard B12 white finish.
The Perforated Return Diffuser (PDDR) is designed to match the PDF and PDN perforated supply diffusers in appearance and detail. The PDDR is a perforated face diffuser designed for return applications. With a wide array of sizes and frame options, the PDDR is suitable for most ceiling types. This product is available with round or square inlet options and comes in the standard B12 white finish.
The VCR9 round, galvanized steel, radial style damper provides airflow adjustment at the diffuser or plenum 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.
