    Evening,

    I have a xpelair model 90843AW in the bathroom from when we moved in. The led comes on when the main light is switched, so it's powered, but it's not actually worked since we've been there.

    It doesn't look like the model is in production anymore, so a direct replacement is pricey, but I'd rather not have to mess with ducting and so on. I'm wondering if anyone knows current xpelair model that would be a like-for-like in terms of fittings, ducting size etc for the 90843AW, please?

    Thanks

    Google isells
    They have a good website and a good range

    However if there’s a loft above the bathroom do the right thing and make a little effort and install an in-line fan in the loft - you’ll be so glad you did

    A farmer friend of mine used to have a massive collection of John Deer and Massey Ferguson’s literally he had that many of them he lost count, he was obsessive. His long suffering wife couldn’t cope with the competition so she left him for a neighbouring farmer’s young son.

    Finally gave up the hobby and massive collection, that kind of ex-tractor fan?

    Funnily enough, I just bought a Positive Input Ventillation System from Amazon and when it came I noticed the seller was ‘isells’

    You could contact Xpelair, and ask if they have a replacement part;

    Spare Parts

    But probably just as cheap & quick, to obtain the their replacement model.

    David, I would just go out and buy an extractor fan grille and an in-line fan and just replace it.

    The ducting is more than likely to be the same size- you might just need some cable ties to fix the ducting on to the fan and grille.

    There will more than likely be enough dicting already there. Just break into it with a Stanley knife and cut the wire in the ducting with some wire cutters.

    Obviously I have no idea of the set up you have so this is based on how I think it will go, your set up might be different.

    I agree with your advice. However, a quick search of that discontinued model (number), suggest it might just be a humidistat model. Best check with the manufacturer, or inspect the wiring supply, before replacing with something different.

    if you’ve got good access from above consider putting a larger 125mm or 150mm grille - it’s all about airflow
    Likewise an in-line will probably give you 259m cubed (per hour)of air movement
    Your surface mount one is probably about 85m cubed

    Thanks folks. The existing extractor is wall mounted but I'm going to look into ceiling mount inline. There's a seperate shower room too so I need to check in the loft to see where that vents to as I may be able to hook into it.

    If You do tap into the shower fan then a couple of inline "Flap valves" will be required to prevent one room venting into the other.

    Be a bit careful with those shutters. They don’t tend to seal particularly well and can sometimes cause a back draft into another room.

    Best bet is two separate ducts to atmosphere or if you do use one, fit the ‘Y’ branch as close to the terminal as possible.
