The IO HVAC CONTROLS SC-VD-BK is a diffuser baffle designed to block off one of four sides on a compatible VD-series diffuser. This accessory redirects airflow by eliminating one discharge opening, allowing technicians to customize air distribution patterns in ceiling or wall-mounted diffuser installations. At 6.25 inches wide, 0.25 inches thick, and 23.75 inches long, the baffle fits directly into the diffuser frame without additional hardware. HVAC service technicians and sheet metal installers use this component when a four-way diffuser needs to be converted to a three-way, two-way, or directional throw configuration to suit room layout or supply duct positioning.
This baffle is used in commercial and residential HVAC air distribution systems where VD-series diffusers are installed in drop ceilings or finished spaces. Common applications include conference rooms, offices, and retail environments where airflow direction must be adjusted to avoid obstructions, control drafts, or meet load calculations. The baffle slots into the diffuser to seal off one discharge side, effectively changing the throw pattern without replacing the entire diffuser assembly.
Designed for use with IO HVAC CONTROLS VD-series diffusers that accept side-blocking baffles. Consult the diffuser model documentation to confirm baffle compatibility before installation.
Installation is performed by a qualified HVAC technician or sheet metal installer. Shut down the air handling unit and confirm zero airflow before accessing the diffuser. Slide the baffle into the designated slot on the diffuser frame, ensuring it seats flush to prevent air bypass. Follow local mechanical codes and the diffuser manufacturer's instructions for proper baffle placement and securing.
