The Modulating Automatic Round Damper is a round damper with a 24-Vac, floating-control type modulating motor for bypass and zone damper control. It is constructed of 22-gauge galvanized steel and has male (crimped) and female (uncrimped) ends to connect to any rigid or flexible round duct. It is available in 5, 6, 7, 8, 9, 10, 12, 14, 16, 18 inch diameter sizes. The motor timing is 90 seconds open to closed.

Honeywell Zoning - Helpful Tips:

To learn more about this brand visit our Honeywell brand page.

On average HVAC is 65-75% of your monthly utility bill. According to the manufacturer, by using this zoning product you can reduce this part of your utility bill by 30%.

Installation of a Zoning System provides substantial savings over installing an additional HVAC or "split" air-conditioning system. Additionally one unit compared to two saves money in operating costs and energy. Maintenance costs are also decreased when comparing the expense of replacing dampers to the inevitable replacement of a furnace or air conditioning unit every 10-15 years.
