Will this bathroom extractor fan fit the vent?

[pretzelz]

Hi,

There is a "silent" bathroom extractor fan I'd like to order from the Internet.

This would need fixing into or at the face of the existing ceiling vent in the bathroom. (concrete ceiling, circular hole leads straight up and out) However, the vent is about 10.5" x 11.25", larger than the extractor fan which is 8.2" x 8.2".

What would the easiest way of installing this be, in an aperture which is seemingly too big?

-- Also, do you think the extractor fan will be a better solution to just having the vent? Bathroom is about 3metres by 1.5 at a guess. If it's not worth it I could leave it out.

Many thanks!

when you take the vent off, what size and shape is the duct?

Looking upwards to the sky, the vent is a clear circular vent. I imagine the diameter would be about an inch, if that, less than the dimensions given for the square vent covering. So I'm guessing the circular vent has a diameter of about 9.5". (away from home at the moment, can't measure precisely)

Thanks for any advice.

The link is to a 4inch fan,? ideally fit a larger 6inch to get effective air movement, ensure fan is suitable for ceiling mounting, not all are.
