Resideo by Honeywell ZD14X20TZ 14x20 Inch Rectangular Parallel Blade Zone Damper 24V

The Resideo by Honeywell ZD14X20TZ is a 14-inch by 20-inch rectangular parallel blade zone damper designed for precise airflow control in forced air HVAC zoning systems. This power-close and spring-open damper operates with a 24-volt motor to manage circulating air in heating, cooling, and ventilating applications where normally-open operation is required.

Key Features:

• Kevlar gearing reduces wear, more than doubling damper life
• Solid construction using extruded aluminum frame and blades
• Parallel blade design for low leakage performance
• Adjustable range stops with mechanical visual position indicator for damper status
• Simple, easy-to-wire, two-wire installation
• Fail-safe, normally open operation
• All ZD dampers are 4 inches thick

Technical Specifications:

• Motor Electrical Rating: 24 Vac, 60 Hz, 8VA
• Motor Torque: Minimum 71 in.-oz.
• Energized at rated load: 30 seconds; De-energized (spring return): 10 seconds
• Maximum Static Pressure: 1 in. wc
• Leakage: Less than 1% at 1/2 in. wc

The ZD is typically used with the TrueZONE systems and other electronic zoning systems, providing reliable zone control for residential and light commercial applications. The damper motor is mounted on the 20-inch side and can be installed in any orientation for flexible ductwork integration.
