Ductwork used to channel or direct air to spaces throughout a building can impact the efficiency of the structure’s HVAC system. That’s why it’s important to properly design and install ductwork and its components, including the dampers used to regulate or stop airflow.
As they select dampers that will best suit their ductwork design, HVAC construction engineers have the option of specifying either airfoil, triple-V groove or modified flat blades. Airfoil blades offer several advantages, beginning with blade strength.
