Honeywell Round Retrofit Zone Dampers
¹
The RRD is a round, low voltage damper that is easily inserted into rigid round ducts for retrofit zoning in forced air heating and cooling systems. The damper is used with Honeywell EMM3, EMM3U, TZ4, W8835 and similar zone control systems. The power open, power closed actuator draws 2.5 VA allowing multiple dampers per zone, but delivers high torque for reliable operation.
* Gaskets around blade and under motor housing provide low internal leakage and very low external leakage |
