Fan suitable for Zone 1

[Craig2022]

I've recently been asked by a family member if I can install them a fan in their en-suite due to moisture.

The fan isn't able to be drilled through the wall due to it being an old terraced home, meaning it can only go above the shower as this is the only area where ducting is available to go directly up to the loft space and onto a roof tile.

So i currently seek a fan that's suitable for 'Zone 1' and is able to extract a good rate through a run of about 3/5m of ducting to the roof tile, also has an over run and is moderately quiet, don't want them having the whole house woken every time they go for an early morning shower!

Any recommendations/links?

I've been reading a lot of previous posts about this being protected by a 3 amp fuse, I do believe that when this en-suite was built (about 6 months ago) they had a new lighting switch branched from a junction box within the loft space to give feed for the en-suites 3 down lights. Should I disconnect this leg, put it through SCFU, then take a feed from here to connect into the junction box?

This is will be given the whole of the en-suite a 3 amp additional protection.

Circuits are also protected with a 30mA RCD

1. any fan with a IPrating of IP44 can be fitted in zone 1. 240V is acceptable.

2. you only need a 3A fuse if MI instructions specify fitting one. fit a fan isolator, not a SFCU, and if necessary, use an isolator that is fused.

I didnt realise you could get a fan isolator that was able to take fuses, do you have a link to one? Already had the idea of taken a 3c from switch to a fan isolator, then 3c to the fan. Just been struggling to finding a suited fan for the location.

Is this an acceptable fan? The family member was recommended this one, but I was unsure if it would be powerful enough for the job, also if it had all the necessary protection

you just need to ensure that it's IP444 or better, and that it's capable of performing with the length of ducting that you have fitted. epicair fans specify what length of duct they can cope with.

Just been round to the house and the ducting run is about 5/6m! so the greenwood would not be compatible as it says up to a ducting run of 3m. Gonna go to see a wholesalers about one on Monday morning, thanks for the link to the 3pole fused fan isolator

If you are going five or six meters then most axial fans will be very poor over that distance, an inline fan in the loft (avoids IP rating problems with bathrooms) or a centrifugal fan would be more appropriate.

I've been currently looking at the centrifugal fans, they seem to be ticking each of the boxes so far. is there a particular way that the ducting should be positioned?

yes.from the fan to the outlet. joking aside, jusrt so there's no kinks, and could be advantageous to insulate ducting with some itchy=poo on top to reduce condensation of the vapour.

Haha great . Yeah I was gonna use insulated ducting due to the run it's gotta do. Cheers for all info!
