Io Hvac Controls VD-RK-06 Vav Diffuser Retrofit Kit

Product Description

The IO HVAC CONTROLS VD-RK-06 is a VAV diffuser retrofit kit designed for 6-inch neck diffusers in variable air volume HVAC systems. The kit provides the hardware needed to adapt existing ceiling diffusers for VAV control without replacing the entire diffuser assembly. Mounting screws are included, allowing technicians to complete the installation with standard hand tools. This kit is appropriate for commercial and light commercial interior spaces where zone-level airflow control is being added or upgraded by a qualified HVAC technician.

The VD-RK-06 is used in VAV system retrofits where existing ceiling diffusers with 6-inch necks are being brought under automated airflow control. Typical applications include office buildings, classrooms, and multi-zone commercial spaces undergoing controls upgrades. The kit is designed to work with IO HVAC CONTROLS VAV diffuser actuator and controller assemblies as part of a larger VAV zone control system. Installation is performed by licensed HVAC technicians familiar with low-voltage VAV controls and air distribution systems.
