Description

The RD-HD Series of round Hand Dampers are
designed for field adjustment of Differential
Pressure and Velocity Control on Round Bypass
Air Duct Runs.
Pursuant to ACCA Manual Zr, "A balancing hand damper should be installed in the bypass duct" for setting adequate resistance to bypass flow. The RD-HD includes a Heavy Duty Manual Quadrant allowing Easy & Accurate Field Adjustment of the Pressure Drop through the Bypass duct run.
In addition, the RD-HD has a truncated blade design resulting in 70% maximum closure. This superior design ensures minimum bypass flow even if the hand damper is accidentally closed all the way.
The RD-HD is designed to provide reliable and quiet Balancing Function at velocities up to 2700 feet per minute.
RD-HD dampers are easy to install and adjust. The superior design insures long life with no maintenance and a 5 year warranty. See Application Note #090376A0169 for installation and setup instructions.
