This motorized volume control damper is designed for ventilation professionals managing airflow in exhaust or supply systems. It regulates air passage at wall or curb installations and can be positioned vertically or horizontally.

The damper has a 1-1/2-inch flanged frame with welded corners and 6-inch-wide center-pivoted blades. Its parallel-blade design provides 90-degree rotation. Stainless steel jamb seals help limit light air and moisture entry. An internally mounted, factory-installed 100-240V power-open/spring-close motor with end switches is included. Product dimensions are 24 inches wide, 9 inches deep, and 23 inches high.


Key Features:

  • Motorized operation: Power-open and spring-close action supports controlled airflow adjustment.
  • Parallel blade action: Center-pivoted blades rotate up to 90 degrees for volume control.
  • Flanged welded frame: Welded frame corners add strength at the installation point.
  • Stainless steel jamb seals: Helps reduce the entry of light air and moisture.
  • Flexible mounting orientation: Can be mounted vertically or horizontally on walls or curbs.

Choose this 20-inch flanged damper for motorized airflow control in supply or exhaust ventilation installations where wall or curb mounting is needed.
