Model XG-DD-500 air terminal units regulate the flow of conditioned air in a dual duct air distribution system. The air terminal unit receives both heated and cooled air and mixed in a plenum (provided by others) to reach the desired discharge temperature. The XG-DD-500 offers a CFM range capacity from 80-4,400 cfm in multiple units sizes, and is AHRI Certified, ETL Listed, UL 1995. XG-DD-500 complies with NFPA 90A and UL 181.

Capacities ranging from 80-4,400 cfm in multiple units sizes.

Pneumatic, electric, analog, or direct digital controls available.

Unequal inlet sizes are available as an option.
