Feature

To install Normally Open Adjustable Motorized Damper Sleeves, you simply slide the sleeve into the item you are attaching to and fasted with sheet metal screws, and conceal the seam with duct tape. We do recommend that you seal around all sheet metal to sheet metal connections with a duct sealant to prevent air leakage, and increase the efficiency of your HVAC system. This damper does not have a 100% seal it's used for air balancing, not air termination.
Fully adjustable for both powered and unpowered positions.
Fresh air intake and make up for better air quality
Can be integrated with the existing zone controller system or any controller supplying 24 volts AC or can operate as a standalone device using the included transformer.
Safe, ETL listed 24VAC/20 VA plug-in transformer included
Free-wheeling coupling between motor and damper shaft for long lifeBalancing dampers are simply manual dampers encased in a galvanized sheet metal sleeve. Each branch should have a balancing damper installed. That way, it's possible to regulate the airflow by adjusting the position of the damper. They should be located in areas that are easily accessible for adjustment. The ductwork regulates the flow of air and redirects it to specific places of a house.
