Io Hvac Controls D-Z1-2408 Zone Damper Assembly 24x8

Product Description

The IO HVAC CONTROLS D-Z1-2408 is a two-position zone one damper assembly designed for use in ducted HVAC zoning systems. It controls airflow through a single zone by moving between a fully open and fully closed position, allowing the system to direct conditioned air only where it is needed. The damper measures 24 inches wide by 8 inches in height, with a depth of 6 inches, and weighs 7.5 pounds. Licensed HVAC technicians install this component as part of a multi-zone forced-air system to improve comfort and energy distribution across separate areas of a building.

This damper assembly is suited for residential and light commercial forced-air zoning applications. It fits into ductwork as a zone one damper, typically controlled by a zone control board or thermostat panel. The two-position operation makes it compatible with simple on/off zone control systems where modulating airflow is not required. It is installed by HVAC professionals during new zoning system builds or as a replacement damper in an existing ducted system.

Key Features

• Two-position operation: fully open or fully closed for straightforward zone control
• 24-inch width by 8-inch height duct opening fits standard rectangular duct sizes
• 6-inch depth allows for installation in typical duct clearance conditions
• 7.5-pound assembly weight supports standard duct mounting without additional bracing in most applications
• Designated zone one configuration for use at the primary zone position in a multi-zone layout

Compatibility

Designed as an OEM-style replacement or new-installation damper for residential and light commercial ducted HVAC zoning systems requiring a two-position zone one damper in a 24 by 8 inch duct opening.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handler or furnace and disconnect power to the zone control system before beginning work. The damper must be oriented correctly relative to airflow direction as indicated by the manufacturer markings on the assembly. Wiring to the zone control board should follow the zone panel documentation and comply with NEC low-voltage wiring requirements.
