For inline ducting use Manrose 414CD instead
Prevents backdraught when the fan is not in use. Designed to meet and conform to the latest building regulations. The designs have significant advantages over conventional round systems. Its low profile enables it to be concealed when installed along the top of wall units.
Note: As of 2015/October: Item may now be manufactured with Metal springs rather than a plastic strip. This does not affect the performance of the item.
For use with Manrose inline fans
PLEASE NOTE - This product is only supplied with one spring / plastic strip. This product is designed for use with Manrose small fans. For inline ducting use Manrose 414CD or DUCVKC303 instead

Ive just received delivery of R1230 4" in line Manrose shutter with only one spring attached is this correct ? Many thanks Phil
Hello Phil,
This is indeed correct. This is how the item is supplied from the manufacturer. They occassionaly change their design and I believe there were reported problems with the two-spring design, which is why they have switched to just a single spring which is more than sufficient for the item's application.
Please let us know if you have any other queries.
With kind regards,
Michael
Please advise how this back draught shutter should be installed to operate correctly with the above fan model. Thank you.
Hello Des,
The MAN1230 In-Line Damper is designed for use with the Manrose ID100 fan range, which has sligtly different dimensions to the MF100 range.
It can be used with the MF100T fan but is not designed to fit straight on, and so therefore it would need to be taped or otherwise affixed to the MF100T.
Please let me know if you have any further questions.
Kind regards,
Michael
I was wondering if this product diameter is 100mm so that it can be put into the wall of an existing system. Thanks
Hello Greg
Thank you for your question. This item fits into 4" ducting and is installed horizontally into your duct run.
Will this item work in a vertical position on the exhaust from a cooker hood with goes vertically upwards
Hello John
Thank you for your question. The Manrose backdraught shutter only works in the horizontal position where as our Kair backdraught shutter works in the vertical & horizontal position. Product code for this item is QS256.
would like to know if this item goes on the vent inside or after the fan and does it fit in side the flexible pipe thank you
Hello Howard
You state that this mounts horizontally which I assume means the duct run. Is there a product that has shutters which mounts in the soffit to exhaust outside?
Hello
Thank you for your question. Depending on the size of your soffit we do a 76mm soffit grille product code for this item is QS2790 or a 100mm grille with fly mesh the product code for this item is QS209. If I can help any further please do not hesitate to contact me on 0208 463 9683
Kind Regards

I am considering buying a MF100T fan. You have mentioned this is not desingned for that fan. Which one is designed for that fan please?
Hello Bob
Have old extractor fan fitted above ceiling in shower with about 5ft of flexible hose leading to outlet in soffit. Fan is in middle of hose. Need to stop draught from this when fan not working. Flexible hose is old 4-inch and existing plastic cover horizontal on ceiling (old Silavent D154) has circular outlet about 98mm o/d and 95mm i/d. Is this correct product to fit between cover and hose and do I need any extra fittings to make it work properly? Thanks
Hi Chris. This item is designed to be fitted either on the back of wall mounted Manrose fans, or inside the duct run. It is best to use rigid duct if you are going to do that, and you may well need a couple of male couplers to hold it in place. There is a video on our website. Alternatively, you could look at the Kair Cowled Grilles. These have a damper flap behind them, tha pretects against backdraught. If the wall is exposed to higher than normal winds, then you might want to look at the Stainless Steel version - QS49029.
