4 " EXTRACTOR FAN SUCKS....LITERALLY

[Galvanised]

Last month i fitted 2 4" extractor fans ( one in the kitchen and one in the bathroom ) we bought an ex council house about a year ago which didnt have any extractors so i finally got round to it .

Anyway im finding these fans are rubbish , condensation is still building up in the kitchen and bathroom . Dont ge me wrong they are extracting but not at the rate i want them too....( i want blood sucked out of peoples faces extraction if you know what i mean lol )

Can anyone link me to the powerfullest 4" i can buy as everythings done i can just buy 2 more and fit them.....help please as its like a foggy morning in the house ...

Cheers all...Happy new year as well

If you suck air out of a room then there has to be a way to replace that air from inside the house.

Vent axia ACM100 (T for timer).

Centrifugal. Look at the air extraction figures and tell me you can find a better 4" fan

They have been on SF cheaply recently, but are now withdrawn due to imment price increase.....SF printed incorrectly I believe.

They aint cheap

Got one from the wholesaler today for £60 cash.........we usually pay £80 for a standard and £100 for a timed.

Sorry but it was meant as a helpful comment based on experience.

When the door was shut the fan moved hardly any air. Door open and the increase air flow was obvious.

Louvred panel fitted into lower part of door and room cleared much quicker. Still had a condensation problem but very much reduced.

I agree with Bernard - unless the ventilation is adequate, an extractor fan won't extract anything. After the air pressure in the room has dropped it will just whirl around with the airflow across the fan blades stalled.

A more powerful fan may just create uncomfortable drafts through whatever gaps air can get into the room without any significant increase in air change rates.

Vortice Lineo 100?

For fans, Bernard is spot on, however, from your original post, I guess that your real problem is condensation. Condensation is a serious problem and can be difficult to solve. Simply moving air through the room will not automatically prevent condensation. It can make it worse as the air takes the shortest route inlet to fan and there can be cooling due to the ventilation. One answer is to use a fan, but not to extract the air - to push it in. Air is blown from the roofspace with a very quiet, slow fan and escapes through normal openings. This works quite well and may be a cheap(er) solution than any other. In short, don't try to fit bigger and bigger fans. Stop and work out what is going on. There are a number of websites and you might find that your local council is helpful - what did they try on these houses and what was successful.
Best of luck
