Resideo by HoneyWell TrueZONE Automatic Rectangular Damper

The Resideo by Honeywell TrueZONE Automatic Rectangular Damper is a 24-volt, power-close, spring-open zone damper. It controls airflow through rectangular ductwork in heating, cooling and ventilating systems. It is built for TrueZONE and other electronic zoning systems, and it suits any application that calls for a normally-open damper. It is also called a motorized zone damper or parallel blade HVAC damper.

Key Features:

• Reliable 24-volt spring-return motor with fail-safe, normally open operation
• Kevlar gearing reduces wear and more than doubles damper life
• Adjustable range stops
• Mechanical visual position indicator shows damper status at a glance
• Extruded aluminum frame and blades for solid construction
• Parallel blade design for low-leakage performance and quieter operation with fewer blades
• Simple two-wire installation
• Works with conventional and networked zoning systems

Zone dampers like this let you direct conditioned air to the areas that need it. That helps balance room temperatures and improve comfort. Each variant in this TrueZONE line has the same motor and construction.
