Always calculate the damper's square footage and friction coefficient to ensure the load does not exceed this rating
making it suitable for larger commercial lighting ballast applications
ensuring survival in corrosive environments while maintaining precise superheat regulation
Enhanced Regulation: Utilizes a positive positioner mechanism to overcome valve stem friction and high differential pressures
ZoneFirst RDP-10 Damper Freon Always calculate the damper's squareThe 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
