Greenheck: Damper Control Catalog
February 3, 2005
The new damper control catalog details the manufacturer's damper design and construction features and damper options and accessories. The benefits of the variable symmetric blade design (VSB), which include a high damper free area, lower pressure losses, and low operating torque, are explained, says the manufacturer. Damper performance and testing criteria and quick selection charts for volume control and manual balancing dampers are included. In addition, the literature contains information on the company's actuators.
