Resideo ZD8X18TZ Damper
The Resideo ZD8X18TZ is a heavy-duty 8 inch x 18 inch rectangular zone damper engineered for precise airflow management in forced-air systems. Constructed with a solid extruded aluminum frame and parallel blades, this unit minimizes pressure drop while ensuring a low-leakage seal (less than 1% at 0.5 in. WC) when closed. It features a 24Vac power-closed, spring-return open configuration, making it a reliable fail-safe solution that defaults to the open position during power loss to maintain critical ventilation. The integrated synchronous motor is side-mounted on the 18-inch dimension and utilizes Kevlar gearing for significantly increased service life compared to standard plastic gear trains.
Designed for seamless integration with Honeywell TrueZONE panels and other 24V electronic zoning systems, the ZD8X18TZ simplifies installation with push-in terminals and adjustable range stops for custom airflow balancing. A mechanical visual position indicator and on-board LED operation lights provide immediate feedback for troubleshooting and system verification. This two-position damper is compatible with R-8 insulation requirements, supporting energy efficiency audits and superior climate control in residential or light commercial applications.
Key Benefits- Parallel blade design ensures high-torque performance and minimal air bypass for tight zone control.
- Spring-return open logic provides a fail-safe air path, preventing coil freeze-up or equipment cycling issues during power failures.
- Kevlar-reinforced gearing delivers industrial-grade durability and quieter operation in residential ductwork.
- Direct-drive 24Vac motor features simplified two-wire installation with terminal markings for M1 (Power) and M6 (Common).
- Adjustable mechanical stops allow contractors to set minimum and maximum blade travel for precise airflow tuning.
Is the motor replaceable without removing the entire damper frame?
Yes, the actuator is designed for easy field replacement, allowing for streamlined maintenance without breaking into the duct seal.
Can this damper be mounted in a vertical or horizontal duct run?
The ZD8X18TZ is orientation-independent and can be installed in any position, provided there is sufficient clearance for the 18-inch side motor assembly.
What happens if the 24V signal is lost?
As a spring-return open model, the blades will automatically return to the fully open position if power is interrupted, ensuring system-wide airflow is maintained.
