QDoes this damper opeate in a similar way to a backdraft shutter? Does the damper flap only allow airflow one way?answer nowA
Hello David,
Thank you for your question.
Yes this product only lets air through one way IE: When the fan or cooker hood is in operation it will open and close once not in use.
Please come back to us if we can help any further

QWhats the dampers function? Is it the ductings non return valve or does an air brick contain that? Thanksanswer nowA Hello TrevorThis is a non return valve to prevent back draught from prevailing wind or from when two fans share the same exhaust duct these would be installed in each duct just before the Y or T section.I hope this helps.
Philip Scoltock (verified owner) –
With rectangular ducting inserted in both ends, the damper fouled and wasnt free to open and close easily. Had to remove the damper to ease it a little – easy to do but shouldnt be necessary

Excellent once the flap/damper had been eased to stop fouling on channelling

Good quality plastic. Prompt dispatch and delivery. Thanks
