Marketing Information
The RD-HD series of manually adjusted round volume control dampers are designed to control and limit air volume (CFM) on round duct runs. The RD-HD allows a technician to properly balance the HVAC duct system during a test and balance procedure. The RD-HD includes a field adjustable high quality Rossi® manual quadrant, with easy to set incremental locking positions. The RD-HD is constructed from 24 ga galvanized steel with stiffening beads at both ends of the shell. The blade is heavy-duty 20 ga galvanized steel and is designed to provide reliable and quiet volume control, at nominal to moderately high duct velocities. RD-HD balancing dampers are easy to install and adjust. The superior design insures long life with zero maintenance and a 5 Year warranty.
