Io Hvac Controls SC-VDR-10 Round Vav Diffuser

Product Description

The IO HVAC CONTROLS SC-VDR-10 is a round variable air volume (VAV) diffuser designed for ceiling-mounted supply air distribution in commercial and light commercial HVAC systems. It features a 10-inch neck connection and a 23-inch face diameter, making it suitable for larger zone coverage in VAV air handling applications. The unit integrates with VAV control systems to modulate airflow based on zone demand, supporting precise temperature management across occupied spaces. Licensed HVAC technicians and sheet metal contractors are the primary installers for this type of equipment.

This diffuser is installed in suspended ceiling systems as part of a ducted VAV distribution network. It is suited for commercial office buildings, retail spaces, schools, and other facilities where zoned airflow control is required. The 10-inch neck interfaces with round ductwork of matching diameter, and the 23-inch face provides broad, even air distribution across the occupied zone. The overall unit dimensions of 24.25 inches wide by 12.125 inches tall by 25.75 inches deep should be confirmed against ceiling plenum clearance during layout and rough-in.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with applicable mechanical codes including SMACNA duct installation standards. Shut down the air handling unit and de-energize the VAV controller before connecting the diffuser assembly. Verify plenum clearance against the unit depth of 25.75 inches prior to rough-in. Confirm duct alignment and secure the neck connection with appropriate fasteners and sealant to prevent air leakage.
