Do you have recommendations when I'm looking for an extractor fan that would be able to extract in a rate of 4600 CFM? (7800 cubic meters per hour)

It would be nice if it fits to some kind of carbon filter too.

Any brand names or webpages? Anything?

I live in Europe.

The chances are that with 7800m3 you're going to need multiple fans at different exit points within the room to create the amount of exchange you require.

Thank you for the information, J.

One question though. How much extraction is there going to be if you have two extractor fans blowing which are both rated at 2000m3/h ?

It isn't going to be 4000m3/h, is it?

My understanding is that it should be.


I've seen grows with multiple exhaust fans and I would assume that if you have 2x2000m3/h fans you are essentially removing 4000m3/h of air volume.

Nothing else logically makes sense.

If you have a 20L container of water and 2 holes in the bottom it will remove twice as much water than if there was one hole.

Now it makes sense to me too.
