Manrose Backdraught Shutter
Related Products
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.
Will not connect to ducting without connectors.
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.

QCan this be fitted inside a 5 flexible duct by pushing it in through the exit hole, which is horizontal?answer nowA Hello EwenThank you for your question.

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

Is this correct product to fit between cover and hose and do I need any extra fittings to make it work properly? Thanksanswer nowA 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.
Just received the above from you. I note only one spring . Do you do a two spring version and is the one spring ok for horizontal and vertical fitting

QJust received the above from you. I note only one spring . Do you do a two spring version and is the one spring ok for horizontal and vertical fittinganswer nowA Hello GrahamYes the Manrose backdraught shutter is fitted with just the one spring as standard. The spring is provided so it can be installed in a horizontal or vertical plane as gravity will close it if fitted vertically.

QI am considering buying a MF100T fan. You have mentioned this is not desingned for that fan. Which one is designed for that fan please?answer nowA Hello BobThank you for your question The QS256 back draught shutter will do your application. This item will require a female sleeve product code QS1586 or a piece of 100mm pipe if you are connecting straight onto the fan as both connections are male. If I can help any further please do not hesitate to contact meKind RegardsAnita
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?

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
-
Qwould 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 youanswer nowA Hello HowardThis should be located after the fan and before the ducting to the exhaust vent.This particular item is only compatible with Manrose In line fans and ducting, if you are unsure of the manufacturer of either the fan or duct I would recommend product DUCVKC303 which is more likely to be compatibleI hope this helps

QWill this item work in a vertical position on the exhaust from a cooker hood with goes vertically upwardsanswer nowA 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.

Please advise how this back draught shutter should be installed to operate correctly with the above fan model.
Thank you.

QPlease advise how this back draught shutter should be installed to operate correctly with the above fan model. Thank you.answer nowA 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
Ive just received delivery of R1230 4 in line Manrose shutter with only one spring attached is this correct ?
Many thanks Phil

QIve just received delivery of R1230 4 in line Manrose shutter with only one spring attached is this correct ? Many thanks Philanswer nowA 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 items application.Please let us know if you have any other queries.With kind regards, Michael

Great product and fits nicely into my vents and prevents blowback of drafts. The service was fantastic and delivery was quick.
Looks OK appears to work
Works very well
This is for the second Manrose fan to which I going to add this type of fitting. The first one worked and this one also seems to be ready to instal, the one spring seems strong / effective enough – great expectations! (It opens with a gentle blow on it and closes easily.)
Ive only checked its operation along with all the other parts that I am planning on using for my bathroom in-line extractor system and it works but I cant say how well it will do to prevent any potential back draught until it is in place and commissioned.
