Io Hvac Controls SC-VDR-06 Round Vav Diffuser

Product Description

The IO HVAC CONTROLS SC-VDR-06 is a round variable air volume (VAV) diffuser designed for controlled airflow distribution in HVAC systems. It features a 6-inch neck and a 14-inch face, making it suited for ceiling-mounted supply air applications where zone-level airflow control is required. The SC-VDR-06 integrates a damper mechanism that modulates airflow to meet varying load conditions in the served zone. Licensed HVAC technicians and mechanical contractors install this type of diffuser as part of a VAV terminal unit or ducted distribution system in both light commercial and residential applications.

The SC-VDR-06 is intended for ceiling installation in ducted VAV systems where supply air is delivered through a round neck duct connection. It is commonly used in office spaces, retail environments, multi-zone residential builds, and light commercial projects where precise airflow control at the diffuser level is specified. The 14-inch face plate provides broad, even air distribution across the conditioned space. HVAC mechanical contractors specify this diffuser when the design requires integrated airflow modulation without a separate terminal box at each outlet.

Key Features

• 6-inch neck connection fits standard round duct collar for straightforward duct interface
• 14-inch face diameter provides wide, even supply air distribution at the ceiling plane
• Variable air volume design allows airflow modulation to match zone load conditions
• Round diffuser profile suits standard grid and drywall ceiling installations
• Compact depth of 12.875 inches accommodates typical plenum clearances above ceiling

Compatibility

Designed as an OEM-style VAV diffuser for ducted ceiling supply air systems utilizing a 6-inch round neck duct connection in light commercial and residential VAV applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or mechanical contractor familiar with VAV distribution systems. Shut down the air handling unit and de-energize any associated controls before installing or servicing the diffuser. Ensure the round duct collar is properly secured and sealed to the neck connection to prevent air leakage at the joint. Verify ceiling structural support is adequate for the diffuser weight prior to final mounting.
