Which size Maxxfan Deluxe do i need
353mm (350 model) or 406mm (400 model) A misconception when ordering Maxxfans is that 400 model is bigger than the 350model and allows more light to pass through the fan. Actually they are both the same unit and interchangeable. The different however is the roof flange and the inner garnish ring are two different sizes. See here So why go for the 400mm model? well the only reason to go with the 400 model is if you have your aperture already...
