8" RVK 200E2-L1 Extraction Fan - 950m3/hr
What size of fan do i need?
1 - Measure the height, length and width (in metres) of the growing environment.
2 - Multiply together (H x L x W) to give you the cubic metre volume.
3 - Multiply this figure by the mount of air changes per hour that you require (eg. 20)
4 - This is the size of fan required to exchange the air 20 times per hour
5 - Buy a fan slightly above the figure calculated if possible to ensure adequate ventilation.
Please note that airflow drops over distance / bends in ducting so bear this in mind when choosing your correct fan!
