Honeywell Home ZD8X8TZ/U 8 in. x 8 in. Parallel Blade Damper
The Honeywell Home ZD8X8TZ/U is an 8 in. x 8 in. parallel blade zone damper designed to control circulating air in residential and light commercial heating, cooling, and ventilation systems. Featuring a reliable 24V spring-return motor, the ZD operates as a power-close, spring-open damper for applications requiring fail-safe, normally open operation.
Designed for use with Honeywell Home TrueZONE systems and other electronic zoning controls, the ZD8X8TZ/U provides dependable airflow management while simplifying installation and maintenance.
The damper features a durable extruded aluminum frame and aluminum blades for long service life. Its parallel blade design provides low-leakage performance while using fewer blades for quieter operation.
Installation is simplified with a two-wire connection, flexible mounting orientation, adjustable range stops, and a mechanical position indicator that allows technicians to quickly verify damper position.

Reliable, Easy-to-Install Zoning Solution
The ZD8X8TZ/U uses a 24V motor to control airflow through HVAC ductwork. When power is applied, the actuator closes the damper. When power is removed, the spring-return mechanism automatically opens it.
This normally open configuration provides fail-safe operation while making the damper well suited for zoning systems where airflow should remain available if power to the actuator is interrupted.
Durable Parallel Blade Construction
The damper is manufactured with an extruded aluminum frame and aluminum blades for durability and dependable long-term operation.
Its parallel blade configuration provides low leakage of less than 1% at 0.5 in. w.c. while the reduced blade count helps minimize operating noise.
Kevlar gearing inside the actuator helps reduce mechanical wear and contributes to extended damper life.
Easy Installation and Position Verification
The ZD8X8TZ/U features a straightforward two-wire connection for faster installation. The damper can be installed in multiple orientations, allowing the mounting side to be positioned on either the bottom or side of the duct.
Adjustable range stops provide additional installation flexibility, while the mechanical position indicator and LED indication make it easier to determine whether the damper is open or closed.
