I've just purchased a bathroom extractor fan for use in my smallish growroom, which I'm constructing in my attic.
On its own its purge rate is 95 m/hr but with the 2m of vent pipe i have to use this drops to 65 m/hr.

My question is can I use two of these fans. One at each end of my vent pipework. One in the growroom wall and one where it vents to the outside. ie two working in serial mode. Would this boost the extraction rated backup

Would there be any problem with the noise frequencies generated by the fans or such like.

Thanks
all

....in practice...i'm not really sure if it's true though...i was thinkin about the same set up when i build my grow room next month.

If you had two fans...

How about one blowing bad air out as you have it -
and one sucking fresh air in?

Not only would you get good air, but it would increase total circulation greatly

I have one exhaust fan myself, and this is something I've been wanting to do. But I already have enough holes in my walls now hehe...

I have 3 110CFM going in mine and it isn't that loud. You can spend extra cash and get a S model which is silent. I only have 2 1000's in my flower room right now and it sucks w/ the door open (Suspect hwo i got spider mites) it's 93F! If your going to have lots of lights, and it's in the attic. Get a a very powerful blower because heat becoms a problem like the temp rises outside...

I have mine attached at a T then going out. Works ok.. Was ok at 1430W and a 1000W on for 1 hour off for 2 etc.. Just get a good fan you'll be thankful, if not you'll have huge length between internodes like some of mine.. Sucks.

Peace.
