Resideo by Honeywell ZD26X8TZ 26-Inch x 8-Inch Rectangular Parallel Blade Zone Damper

The Resideo by Honeywell ZD26X8TZ is a power-close, spring-open rectangular zone damper with a 24-volt, spring-return damper motor designed to control circulating air in heating, cooling, and ventilating systems. This damper is typically used with TrueZONE and other electronic zoning systems, providing precise airflow control for individual zones in residential and light commercial HVAC applications.

Key Features:

• Power-close, spring-open operation for normally-open damper applications
• 24 Vac, 60 Hz, 8VA motor electrical rating
• Minimum 71 in.-oz. motor torque
• Adjustable damper position range stops
• Redesigned all metal drive train gears
• High temperature outer plastic for hot environments
• Quiet operation
• Less than 1% leakage at 1/2 in. wc
• Rated to operate up to 1 in. wc static pressure

The ZD damper comes complete and ready for installation with the motor and linkage factory-assembled to the damper. All ZD dampers are 4 inches thick, and damper sizes are built 5/32 inch smaller than the listed dimensional sizes to ensure correct fit. This 26-inch x 8-inch model features the actuator mounted on the 8-inch side.

The damper requires 24V to power it closed, and when power is removed from the motor, the damper springs back to its normally-open position. Multiple dampers can be wired in parallel for multi-zone applications.
