I have a 1976 era house with one of these older Xpelair units in it - clearly it isn't modern, it's noisy (as if the blades aren't clearing the housing or part of the unit). So what to do?

 

I'm unsure about replacing it as I fear the hole is much larger than a modern unit will cover, maybe it needs a bearing and I should disassemble it carefully and see (which could lead to replacement)... Any suggestions?

can you isolate and then take off the cover and measure the diameter of the hole?

 

potentially its a standard sizing. I see plumbing plus has thru wall options, but any decent retailer would have somthing sufficent. 

 

If above a stove, then perhaps you could install a rangehood... that would cover up some mess....

Replace with new one. Make an adaptor plate from MDF or ply if required

Look up Simx branded fans. Looking on their website they have 100, 125, 150, 230 and 300mm through wall fans.

I'd be very surprised if you couldn't find a new one to fit the opening.

Here's one place that has them.

Dirt build up on the fan blades can make an extractor get quite noisy. 

 

Causes the blades to get a bit out of balance. If you have the time and ability you could give it a good clean up and if appropriate a drop of lube somewhere and see if it improves. They did build things to last back then.

 

...but it is getting on a bit - Maybe time for something newer - and probably quieter.

Guessing that’s near the oven? Save your pennies, don’t waste money on it rather put it towards a renovation with a proper range hood.

Well, I was at a loose end today so thought I'd have a peek behind the Xpelair.

 

Undid the four screws and removed it from the wall, cleaned it all and put it back. Seems the issue is that there is some movement and you have to push it around with the fan running to get it in the right position to eliminate the noise. Clearly as you pull the string to turn it on/off, there will be some movement and the noise will return. Anyway - this buys me a bit of time... Big hole behind as I suspected, and when running - it's pretty ineffectual anyway.

 

I'll probably look at a rangehood along these lines as the ducting will hide the hole to a large extent

Anyway - this is what I found once the unit was removed for anyone who is curious:
