Internal-Mount Air Control Dampers Misty Ref Plain Type (Slip-In) VCDs feature a specialized frame that is slightly undersized (typically by 5mm) to allow for a smooth slide-fit into standard rectangular ducts. This model is highly favored for branch duct balancing where the damper is hidden away from view.

Key Technical Features:

  • Galvanized Steel Frame: 1.0mm to 1.2mm GI frame providing high structural integrity without excessive weight.

  • Aerofoil Opposed Blades: Our signature blade design ensures a linear airflow response and minimizes pressure drop, reducing noise and energy consumption.

  • Manual Control: Comes equipped with a robust hand-locking quadrant mounted on the side of the duct for easy adjustment.

  • Maintenance-Free Bushings: Self-lubricating nylon bushings prevent “seizing,” ensuring the damper remains adjustable for years to come.
