Io Hvac Controls VD-10-SD Auxiliary Vav Diffuser

Product Description

The IO HVAC CONTROLS VD-10-SD is an auxiliary VAV (variable air volume) diffuser designed for use in ceiling-mounted HVAC distribution systems. Featuring a 10-inch neck and a 2 ft x 2 ft face panel, this diffuser integrates with VAV terminal units to deliver conditioned air into occupied spaces with controlled airflow. At 19.5 pounds, it is a substantial unit suited for commercial and light-industrial applications. Licensed HVAC technicians typically handle selection and installation to ensure proper airflow balance and system performance.

This diffuser is intended for ceiling grid installations in commercial or institutional environments where VAV air distribution is required. The 2 ft x 2 ft format is sized to fit standard suspended ceiling grid openings. It functions as an auxiliary diffuser, meaning it is typically paired with a primary VAV terminal unit to extend airflow coverage in larger zones or multi-diffuser branch configurations. HVAC mechanical contractors and sheet metal technicians are the typical installers for this type of equipment.

Compatibility

Designed as an OEM-style auxiliary diffuser for use with VAV terminal unit systems in commercial ceiling grid installations requiring a 10-inch neck connection.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified mechanical contractor. Shut down and de-energize the VAV system, including any associated controls, before beginning installation. Verify that the ceiling grid structure can support the 19.5-pound weight of the unit prior to mounting. Ductwork connections at the 10-inch neck should be properly sealed and secured per applicable mechanical codes and the authority having jurisdiction.
