ZoneFirst RDP-10 Damper Freon protecting the heat exchanger andThe ZoneFirst RDP 10 is a heavy duty 10 inch round damper designed for professional grade HVAC zone control systems. Engineered for forced air zoning applications, this unit utilizes a 12VDC motor (model MP12M) that provides power open power closed functionality. Unlike spring return models, this actuator driven design ensures the blade stays in position without continuous power draw once the cycle is complete, improving long term reliability in
