  • PERFORMANCE DUCTWORK INTRODUCTION

    Control dampers are used to control flow, pressure, or temperature of a duct system. Opposed blade louver dampers are generally used when control is required. These dampers function by rotating adjacent blades in opposite directions (one clockwise and the next blade counterclockwise).

  • Opposed Blade Damper

    Example 17.4 shows that, for a given design system flow rate and pressure drop, an opposed blade damper will be approximately twice the size of a parallel blade damper. Having considered this, the choice of damper will then depend on a number of other factors, including the following: • Convenience of making the duct connections—the ductwork sized for other plant items may more easily
