A useful tip to take note of is that running a larger fan/ducting and filter setup than you think you need will allow you to turn down the speed with either an Evolution 12 amp Digital Temperature and Humidity Controller or a Manual fan speed controller and this cuts down airflow noise dramatically. Furthermore, why not upgrade to Acoustic Ducting- a one time purchase that will reduce airflow noise forever or use Padded Collars which are very useful for a better join between fan and filter or ducting and they substantially reduce vibration and noise.
This 8" 2000mm RVK has an output at full speed of 750m3/hour. The 200/500mm filter will match output and be more than adequate to remove odours. The 2.5m of 8" standard ducting is supplied to help with connecting your equipment.
