does this product shut with gravity,or is it spring loaded, is it floppy when its windy
The item does not contain a spring and therefore pivots based on gravity and fan pressure.
The shutter is designed to only open one way and therefore the item will not flap 'backwards' due to the wind, although if there is more pressure on one side than is being generated by teh fan your shutter may struggle to open.
Does this need to be inserted in a horizontal duct or can it work in a vertical run. Also can it be fiited at the intake side of the fan? Thanks.
Thank you for your question. Yes the backdraught shutter has to be installed horizontal. If installed vertically it would be open all the time. I would recommend it to be installed just before going out though the wall.
I have a 125mm/6" extractor fan ducted out through the outer wall - Are you going to or plan to supply this product for a 6" duct. All the kitchen fans I have used are 6" this would be great if you did
Thank you for your question. We do supply this item the product code for this item is QS282 this is a 6" backdraught shutter you stated 125mm which is 5" we also do a backdraught shutter in this size the product code for this item is QS269.
I have handled these products before and know how delicate the gravity hinged-flaps can be. Answer 2 states 'cannot be used in vertical run'. Does this not apply to downward pumped flow only? My duct flows upwards to a pitched roof outlet. From memory, the shutter would fall shut, even better than in the horizontal position. Am I right please? Alternatively can you recommend a sprung-shutter type of the same outside diameter? Thank you.
Thank you for your question. The backdraught shutter design has now been updated so this product can now be fitted vertically where as before the shutter would stay open on a vertical install.
If I can help any further please do not hesitate to contact me
