In a curtain damper Type A installation, where are the blades and frame located?

• A. Out of the airstream
• B. Within the frame
• C. In the airstream
• D. At the duct entry

Answer: (C)

In a curtain damper Type A installation, the blades and frame are situated in the airstream. This arrangement is crucial for the damper's function as it allows for effective control of air flow within a duct system. When positioned in the airstream, the blades can either open or close in response to specific operational needs, effectively regulating airflow, pressure, and temperature within the HVAC system. This positioning is essential for achieving optimal performance and efficiency in airflow management. The design of Type A damper typically involves blades that pivot within their frame, which directly impacts the air that passes through. By being in the airstream, the damper can quickly respond to changes in system demands, providing the necessary flexibility for maintaining desired indoor conditions.
