Zone Damper TrueZone ZD Parallel Blade 10 x 12 Inch Rectangular 12 Inch Side or Top Extruded Aluminum Power Closed Spring Open

The ZD is a power close and spring open damper. It has a 24-volt motor used to control circulating air in HVAC systems and used when a normally-open damper is required. The ZD is typically used with the TrueZONE and other electronic zoning systems.

• Mechanical visual position indicator for damper status
• Solid construction using extruded aluminum frame and blades
• Parallel blade design for low leakage performance
• Simple, easy-to wire, two wire installation with a third wire option M4 for LED open only light
• Reliable, strong, 24 V spring return motor
• Fail-safe, normally open operation
