extractor fan size

1888

need a new extractor fan for bathroom, seen one on ebay but unsure of what size i should buy, its a vent axia 100mm, thing is is that the pipe diameter or the size of front grille??

muckybutt

4" fan 100mm equates to, 100mm is the diameter of the pipe. You will find most bathroom fans are 4"

Most 4" fans are not big enough, except for the smallest of bathroom.

I saw one in Wilkos @ 11.99 and the name was familiar but cannot recall.

What is the size of your bathroom as a centrifugal one may be better then a standard fan.

The length of ducting after the fan also matters.
