Round Duct Dampers: Backdraft, Balancing, Iris and Shut-off
Backdraft dampers, balancing dampers, iris dampers, airtight shut-off and multi-vane dampers
Overview
What it is for
Backdraft dampers let air go one way only, which keeps outside air and smells from coming back down an extract. On a recent export order they were 1.0 mm galvanised Z80 with a rubber seal, slipped straight into Ø150, Ø200 and Ø250 duct.
Balancing dampers set the airflow in each branch during commissioning. Iris dampers do the same job in a compact round body. Airtight dampers shut a branch off completely, and multi-vane dampers handle larger sizes.
Tell us whether the damper is for manual setting or will take an actuator, and we confirm the right type.
Make it yourself or buy it finished? If you run your own round duct, our SBTF-1602 spiral tubeformer and SBEM-1250 elbow machine make spiral pipe and bends in house. Many shops do both: make the high-volume sizes and buy the awkward fittings finished. See also how duct fittings are made.

Frequently asked questions
About dampers
Do backdraft dampers nest for shipping?
No. Bends and pipe nest, dampers do not, so they take their own carton space. We include them in the carton plan when we quote.
Can a balancing damper take a motor?
Some types can. Tell us the actuator you plan to use and we confirm the damper version on the quotation.
How long does production take?
Production time depends on the item mix and quantity and is confirmed at quotation. As a guide, a recent mixed order of about 1,900 bends and dampers was produced in 50 working days.
Do you have a price list?
No. Fittings are quoted per order from your take-off, because the price depends on the diameter, gauge, coating and quantity of each line. Send the list and we quote every line.
