48″ SDR100 – Linear Return with 1″ Slot Spacing, 2 Slot, Flange Frame Surface Mount, Screw Mounted Flush End

The SDR linear slot diffuser is designed to satisfy architectural applications that require continuous lengths without compromising air distribution performance. These linear slot diffusers feature fully adjustable, aerodynamic pattern controllers fabricated from extruded aluminum. Aerodynamically designed blades provide a tight horizontal pattern that maintains stability even at low airflow rates, making the SDR ideal for VAV applications.
