Weak extractor fan

    Guys, is there something in particular - like motor pwoer - I should look for in a bathroom extractor. I fitted one recently, wasn't expeinsive, however I'm finding the room steams up quickly when its running. Is there a power rating on them for different types of bathroom or something ?

    Cheers

    It's unlikely to be the fan at fault. Fans are all made to comply with Building Regs.
    Is there sufficient fresh air getting into the room, if not the fan can't extract enough.
    You might need to cut a strip off the bottom of the door.

    Thats possible alright. The doors are fire proof - when they close theres a seal around the edges.

    As well as supply air, if the fan is connected to a duct then this has also to be taken into account. I've often come across installed fans where the effectiveness was reduced to nil due to poor designed/installed ductwork attached to the fan.

    Hi. Sorry to jump into this thread. I am having my attic done at the moment and have been told that the extractor fan in the en-suite bathroom (beneath attic) is poor. It's the one that came with the house when built and doesn't really clear the steam away unless you leave it on for 30 mins for a 5 minute shower! They have quoted €250 for a new one. This sounds a little steep to me. Could anybody advise please? Thanks

    Bathroom Extractor fans are designed to remove smells & not steam. If it was actually sucking steam out, then it would condense around the fan & it would drip. This does not happen. :)

    If it is a very very good extractor fan and includes fitting then it's not totally outlandish. Downdraft and good steam extract was very important for me.
    I bought this one a few months ago and got it delivered through ParcelMotel. It has a automatic shutter on it to block backdraft. Excellent at removing steam and condensation.
    Couldn't recommend it enough.
    Note : The timer module isn't included if you want it to overrun from power switch.

    I just fitted one of these lads, moves serious amount of air and very happy with it....http://www.i-sells.co.uk/manrose-mf100t-mixflo-fan-100mm-inline-duct-fan-with-timer-two-speed-high-performance

    I fitted two of the manrose fans recently too. Very happy with it. €60 odd in elected suppliers, cesco are distributors for them in Ireland.

    Timer can be adjusted from 5-55mins overrun.

    Back draft shutter can be ordered from ATC in Dublin.

    Remember that if the flexible ducting is not pulled tight it creates air resistance.
