Icon extract fan - noisy but works (Cutteslowe OX2)

This is an 8 year old toilet/bathroom extract fan that I have replaced with a new one. Rather than throw it away I am offering it in case anyone has a need for a fan and may be able to fix how noisy it has become, or doesn't care about the noise. It comes complete with mounting kit and screws; visually it is in very good condition - needs cleaning inside to remove the dust build up.
