Extractor fan comparison

[joehat]

Been looking extractor fans for bathroom getting damp from moisture, poor performance extractor I think, but been looking at inline ones and also kitchen ones, does anyone use kitchen ones, providing still suitable up ratings?

what is the question? This post doesn't make sense!

 

[joehat]

Question is at bottom saying does anyone use kitchen ex fans in bathrooms, if they need a higher extract rate to help keep the moisture our Ect.

Apologies if not clear.

Whatever fan you put in you need to make sure that you have air getting into the room (through a vent in the door or a gap under the door?) otherwise the bathroom will always be damp.

Yep, so extractor fan doesn't just create negative pressure, if I've worded that right,,

AND if its venting out through ducting make sure that its a nice straight "route" unlike one 1 saw this afternoon!

AND if it's running through the roof space make sure it's well insulated against the cold and fit a Condensation Trap.

Spot on. And also for long runs of ducting consider using rigid ducting and a centrifugal fan.

Definitely, and make sure it slopes slightly downwards so's condensate runs downwards towards the outlet and to the outside of the building.

Aye, I forgot that point Geordie! Did a thorough job last summer in a house, approx 10m run all in all, rigid inclined ducting, all then insulated, two centrifugals with back draught shutters all over the place. All had been fine til one of the fans failed. Bloody typical, it's a fairly straight forward swap, but loft access is a swine....

Here's a really dull photo of part of it!

Some folks have all the luck!! :sailor:

Definitely. I use the multi-stage type as in the pics below. Excellent performance even with long runs of ducting and they last forever, but they are expensive and you need 3-phase.

He should have room for one or two of those in the loft space above the bathroom.... :rofl:

black manrose inline fan seems good there about £60 though. the cheap ones just wouldn't clear the room (no window in the bathroom)

That looks like an Axial fan.

I'd rather take my chance with this centrifugal& made of metal (no plastic) and it could be cheaper >>>>>Xpelair XID150 Centrifugal Metal Inline Fan (90103AA)

ive not used manrose fans before, i did my time with a firm that did bms.

calling Birmingham air-conditioning out is a bit overkill for a 4" fan lol


the manrose one has a built in timer i cant see anything about a timer on that xpelair fan (personally i sould prefer xeplair)

 

[shanky887614]

anything is better than this type that was in before

i had nothing to do with either so if it fails its not my problem, i didnt buy it or fit it
