Io Hvac Controls VD-10 Vav Ceiling Diffuser 118-710 Cfm

Product Description

The IO HVAC CONTROLS VD-10 is a variable air volume (VAV) ceiling diffuser designed for zoned comfort control in light commercial and commercial HVAC applications. Featuring a 24 x 24 inch face with a 10 inch neck, this unit delivers a variable airflow range of 118 to 710 CFM and operates with a wall-mounted thermostat controller included in the assembly. The diffuser modulates airflow based on zone demand, reducing energy consumption compared to constant-volume systems. Licensed HVAC technicians and sheet metal contractors install this unit as part of a low-voltage VAV zoning system.

The VD-10 is suited for single-zone or multi-zone VAV systems in offices, retail spaces, and similar light commercial environments. It mounts in a standard 24 x 24 inch ceiling grid opening, making it compatible with common suspended T-bar ceiling layouts. The included wall-mounted thermostat provides local zone temperature control without requiring a separate building automation system. Installers integrating this diffuser into new construction or retrofit VAV projects will find the integrated controls reduce field wiring time compared to separate controller installations.

Key Features

• Variable airflow range of 118 to 710 CFM for responsive zone-level control
• 10 inch round neck connection suits standard VAV duct runouts
• 24 x 24 inch face plate fits standard suspended ceiling grid openings
• Wall-mounted thermostat included for local zone temperature control
• Modulating design reduces energy use versus constant-volume diffusers

Compatibility

Designed as an OEM-style VAV ceiling diffuser for light commercial zoning systems requiring a 24 x 24 inch ceiling grid opening and a 10 inch round neck duct connection.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with VAV zoning systems and low-voltage control wiring. Shut down the air handling unit and de-energize all control circuits before beginning installation or wiring the wall thermostat. Verify that the duct runout and ceiling grid opening match the 24 x 24 inch face and 10 inch neck dimensions before mounting. Follow all applicable mechanical and electrical codes, including local adoptions of the IMC and NEC, for duct connections and low-voltage wiring.
