bathroom fan replacement?

[learner123]

Hi Guys
please help me,

My bathroom fan has packed up so i went to replace it,
Only to find i have metal ducting in my walls (i live in a flat)

The fan i took off was a greenwood airvac AX 100T.
I had a spacer as its clear the fan would not fit into the main ducting as they both 4inch pipe's.

the spacer whole is 4.9 inch wide, I think it might be for the window fan's?
I have been to all the electrical shops near me and cant get a replacement to fit on the wall. no one does a spacer with a wide enough width.

What could i use and wear could i get one?

Many thanks & happy christmas to all.

In these situations I usually go and get a direct replacement for the old one. As you've found it saves a whole heap of messing around.
You can get a new AX100T for less than £40 here: http://www.abs-electrical.co.uk/enter.html?target=p_6603.html&lang=en-gb
