These low-cost dampers make it easy to quickly add zoning to an existing duct system. The Retro Damper is the perfect alternative to expensive pneumatic systems that require special plastic tubing and pumps. This damper uses standard thermostat wire and will work with most zone control panels. 

RD-XX Series Retro Dampers can be used with most zone control panels which have the ability to directly power a 3-wire actuator. Each Retro Damper is rated at 24Vac, 2VA. The zone control system transformer must be sized to handle the total VA of all dampers. In some applications, additional dampers may require a relay and separate transformer.


Features and Benefits:

• Compatible with most zone control panels

• 18-gauge steel

• Installation flexibility

• Saves time and labor expense

• Resolves tight space issues

Warranty: 5 years
