Let the Airflow Think for You!
“ Installed it in my home HVAC system and it’s been running great. It responds well and adjusts the airflow exactly how I need it. Build quality feels solid too.” - Jerome D.
Why Get Our Motorized HVAC Duct Volume Backdraft Damper?
✅Automatic Airflow Regulation: Manual dampers require regular adjustments and can shift over time. This damper uses a 24V motor to deliver hands-free, consistent airflow regulation. You save time and ensure each room gets the right amount of air.
✅Leak-Proof Air Direction: Drafts and leaks from loose or poor-quality dampers can waste energy. This damper includes a silicone seal that prevents backdrafts. It keeps airflow directed as intended and stops reverse flow from entering the ducts. The damper can be adjusted up to 90 degrees to regulate the volume of air passing through the duct, providing flexibility in HVAC system balancing.
✅Built for Long-Term Use: Some dampers rust or deform from temperature changes. This model uses 201 stainless steel for strength and corrosion resistance. It holds shape under stress and stays reliable for long-term HVAC use.
📓FREQUENTLY ASKED QUESTIONS
Q: Does this damper work with smart thermostats?
A: Yes, it works with most 24V smart thermostats or HVAC zone controllers that support motorized dampers.
Q: How does it know when to open or close?
A: It responds to signals from a controller or thermostat. Sensors detect room temperature, and the actuator adjusts the airflow accordingly.

Customer Reviews
Using this with a smart zone system. The damper opens and closes automatically based on the room temp. Energy use is definitely more efficient now.
Set it up in a workshop zone and it responds reliably to temp changes. No more fiddling with manual dampers!
Was skeptical at first, but this motorized damper works like a charm. My basement now stays at a consistent temperature.
Feels heavy-duty and well-machined. Stainless build is solid and should last. Fit my 4" duct perfectly with a tight seal.
Installed in a duct run that always had a backdraft issue. The silicone seal does its job perfectly—no more cold air leaking through.
