A 10 year old AXS100DT fan died but was obsolete without a replacement which I thought was suitable (plastic flaps for the backdraft shutters which looked weak and likely to not work well). After shopping around I replaced it with the much quieter SR100TR. The mounting screws being in different places was easy to get around. Previously I used to turn the old fan off when in the bath due to the noise but the new one's quiet enough that I have it on now, so this one is functioning better in my use case.
