Io Hvac Controls VD-08-SD Vav Diffuser 8 Inch Neck

Product Description

The IO HVAC CONTROLS VD-08-SD is an auxiliary variable air volume (VAV) diffuser designed for ceiling installation in commercial and light commercial HVAC systems. With a 2-foot by 2-foot face and an 8-inch neck connection, this diffuser integrates into VAV air distribution systems to provide modulated airflow at the zone level. At 19 pounds, the unit is built for ceiling grid applications where structural support and duct alignment are standard installation considerations. HVAC technicians and sheet metal contractors typically install this diffuser as part of a VAV terminal unit assembly during new construction or retrofit projects.

The VD-08-SD is suited for interior zones in commercial buildings where VAV-controlled air distribution is required. Its 2x2 foot format fits standard drop-ceiling grid systems, making it compatible with typical commercial ceiling layouts. The 8-inch neck diameter allows direct connection to round duct or VAV terminal box outlets of the same dimension. This diffuser is classified as an auxiliary unit, meaning it is typically paired with a primary VAV controller or terminal in a multi-diffuser zone configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor familiar with VAV air distribution systems. Shut down the air handling unit and de-energize associated low-voltage controls before beginning ductwork connections or ceiling grid placement. Verify that the existing ceiling grid structure can support the weight of the diffuser before mounting. Local mechanical codes and SMACNA duct construction standards should be consulted for proper installation practices.
