Description
Reliable Airflow Control with a Backdraft Damper for Ducting
The Backdraft Damper for Ducting is an essential ventilation component designed to prevent unwanted reverse airflow in ducted ventilation systems. Installed directly within rigid or flexible ducting, the damper automatically opens when the inline fan is operating and closes when airflow stops, preventing outside air, dust, insects, odours, and cold draughts from entering your ventilation system.
Ideal for grow tents, grow rooms, hydroponic systems, HVAC installations, and general ventilation applications, the Backdraft Damper helps improve energy efficiency and maintain a stable indoor environment. Its lightweight spring-loaded blades provide reliable operation with minimal airflow restriction, making it suitable for both intake and exhaust ducting.

Why Choose a Backdraft Damper?
A Backdraft Damper is a simple yet highly effective way to improve the performance of any ducted ventilation system. By automatically closing when airflow stops, it prevents reverse airflow, helping maintain consistent temperatures, reduce energy loss, and keep unwanted contaminants out of your ventilation system. Its durable galvanised steel construction and low-resistance design make it a reliable solution for residential, commercial, and horticultural ventilation applications.
FAQs
What is a backdraft damper?
A backdraft damper is an inline duct accessory that automatically prevents air from flowing backwards through a ventilation system when the fan is switched off.
Where is a backdraft damper installed?
It is installed directly inside flexible or rigid ducting, typically near the inline fan or external vent, depending on the ventilation layout.
Can it be used for both intake and exhaust systems?
Yes. It is suitable for both intake and exhaust ventilation systems where reverse airflow prevention is required.
Will it affect airflow?
The damper is designed to offer minimal airflow resistance while providing reliable protection against backdrafts.
Does it require electricity?
No. The spring-loaded blades operate automatically using airflow, requiring no electrical connection or maintenance.
