Ok so the first fan i got moved 100 m3/hr. I didnt think that was enough so iv bought another one which moves 220 m3/hr. But now the noise of the air comi g out of the ducting has doubled. Does any one have any tips on reducing the noise? Thanks.

Hi mate, try a cardboard box on the end pal , cut a hole for the duct and a bigger one for out , if your in a loft make a tunnel with insulation , worked a treat for me .

Luckily it stayed in a tunnel shape and didn't collapse :)
