Description
Backdraught Shutters
Elta backdraught shutters are a simple duct accessory designed to stop reverse airflow when the fan is off. They help prevent cold draughts entering the building and they can also reduce unwanted heat loss through the duct run. Finished in white ABS, they suit a wide range of common duct and fan sizes.
Select models are available for next day delivery.
Why fit a backdraught shutter
- Stops backdraught: helps prevent reverse airflow through the system when airflow demand drops
- Supports thermal retention: reduces heat loss through the duct in colder conditions
- Clean finish: white ABS design that suits most internal plant areas and service spaces
- Multiple size options: makes it easy to match the shutter to the fan or duct diameter
