Resideo ZD22X8TZ Damper

The Resideo ZD22X8TZ Damper is a 22" x 8" industrial-grade parallel blade zone damper designed for rigorous performance in high-static pressure HVACR systems. Built with an extruded aluminum frame and blades, this unit utilizes a 24Vac power closed/spring return open motor configuration, ensuring a fail-safe open state during power loss. The synchronous motor is side-mounted on the 8" dimension, featuring Kevlar gearing and adjustable range stops to provide high-torque, precise airflow regulation while minimizing mechanical wear. Ideal for Honeywell TrueZONE and other electronic zoning panels, the ZD22X8TZ maintains a low leakage performance profile (less than 1% at 0.5 in. w.c.) and is rated for temperatures up to 140°F. Professional contractors value the simplified two-wire installation and the integrated mechanical visual position indicator, which allows for rapid troubleshooting during system startup or maintenance calls.

• Fail-Safe Operation: The normally open spring-return design ensures critical airflow remains unobstructed if the control circuit loses power.
• Enhanced Durability: Features Kevlar reinforced gearing and heavy-duty extruded aluminum construction for long-term reliability in high-cycle applications.
• High-Efficiency Sealing: Parallel blade action and precision-engineered seals deliver low leakage performance, maximizing system efficiency and temperature control.
• Simplified Wiring: Features easy-access push terminals for 24V motor connectivity, reducing labor time on multi-zone HVAC installations.
• Versatile Mounting: The multi-poise actuator can be installed in any orientation, fitting seamlessly into various 22x8 ductwork configurations.

Is the actuator field-replaceable?
Yes, the M847D-ZONE motor can be replaced without removing the entire damper assembly from the ductwork, minimizing downtime during service calls.

Can I use this for fresh air intake applications?
This specific model is designed as a power closed/spring return open zone damper. For fresh air applications requiring a power-open fail-safe, a different ZD series configuration may be required.

What is the maximum static pressure rating?
The Resideo ZD series is engineered to withstand up to 1.0 in. w.c. of static pressure, making it suitable for both residential and light commercial forced-air systems.
