Bathroom Extractor Fan...

firefox1956

I have 2 Vent Axi bathroom fans & they do require cleaning every few years.
You would be surprised how much dust, fluff & talcum powder gets sucked up into them.
You have nothing to loose by having a go cleaning your fan really.
Regarding replacement of the unit........
Might be easier to replace Manrose with Manrose ??
They will probably last as long as any make to be honest.

When was the last time you cleaned it ? Bathroom fans get a build up of damp fluff and dust on the blades which can cause problems. Is the exit clear, again that fluff can block a grill.

molerat... thanks for your input...


...I have a regular list of 'period cleaning / checking etc' around our home that includes the fans every 6 months, sinks and drains every month which keeps an eye on points like this, maybe I have been unlucky with this fan, maybe a Friday one


Our fans are several feet away from the input and output vents and never contain very much debris, but I will check in the morning, thanks.


Kind regards

...you are possibly correct in what you have said, literally replace with like, to avoid anymore problems, as I said to molerat I have this list of points that needs inspection or attention, buy hey nothing in life is certain? except before you say it...death, what a morbid thought, think positive BertieUK.

Sounds like its got dust / build up which is slowing it down.

They are relatively easy to remove and take a look at (and replace if needed - like for like will be easier, but if you can't get the same one it will just be 3 wires to connect). Just make sure you turn off the mains electricity before attempting any of this!

...I will most certainly follow points that you have made even though the unit was checked out last September, and we have been doing some work in the loft space adjacent to where the fan is housed...

As an update - this morning I checked the blades on the extractor fan and found only a light covering of dust on them.


What I did notice was the length of ducting that was being used between the 'vent and inlet port of the unit' was rather excessive and had caused a 'kink in the ducting' which would restrict the air flow considerably.


This maybe, along with the cold weather attributed to the problem slightly.


I will monitor the 'sluggishness of the unit' over the next few weeks but I think that a replacement will be the best solution.


Again, many thanks for your interest and advice.

I am guessing you have flexi-duct, and if so it would be wise to take out this slack and retighten the jubilee clip fixing. Also check the in line fan is higher than the surrounding ducting to prevent condensation build up at the fan. Plus check all the ducting is fully insulated.

Put your mind at ease on all this before you repair, or replace, your fan. Otherwise the next fan might fail prematurely.

...Yes the fan is fitted with a flexi-duct, and the line fan is higher than the surrounding ducting, which from the line fan drops down to the vent outlet.


I will, as you suggest shorten the length to reduce the chance of any kinking in the ducting.


The ducting was attached originally with 'gaffa-tape' to the line motor, which seem to do the job, maybe not as professionally as I would have expected from the installers who did the job in the first place.


I think that it would look a better job if I purchased 'jubilee-clips'...


...I will monitor the fan over the next couple of weeks after this cold snap has gone and replace if I feel doubtful.


Kind regards.

One day, particularly in a hot roof space the glue will degrade. If you have no suitable clip then a cable tie should suffice. Quite likely you have some in your tool box, or man shed?
