Which size RVK will be the quitest?

Hi everyone,

 

A little advice on RVK fans please.

Finally have my grow tent put together in a descreet place, im now deciding on which size extractor  to purchase.

 

Do i go for for an 8" RVK with 6" reducer to fit in the openings of the Black Orchid? Id like to run this fan at 50/60% as its more than adequate for the tent space (1.2x 1.2x 2).

OR

Stick to the 6" L RVK probably running at 70/80%?

 

Can i have some advice on which you think will be the quitest and best value option as cost is very similar, maybe £20/30 more including filter for the 8"?

 

Cheers everyone.

8" fan for that size grow space is just way over the top for me

they also do 2No. different  8 inch fans , the A1 and the L1

a 6 inch L1 would easily cope, and would have to be reduced in speed in that size tent.

They are loud tho.

To give you an idea, I used a 8 inch A1 fan in a 2.4 by 1.2 tent, worked off a fan controller, and it coped with the heat 90% of the time

8 inch worked off a controller will be quieter than a 6 inch worked off a controller, because it will be working at a lower percentage of its output.

If you use oversize ducting on outlet side this will help kill turbulent noise ....You could also box the fan aka leepy box.:oldtoker:

Thats what im looking for.... so if i buy a 8"A1 fan at the same price there abouts as a 6"L1, using the 8" at lower output than the 6" should be quieter if i understand?

Cheers

Leepy box, ive got it now.

Nice one might have to give it a go if it sounds like a jet engine in the attic.

6 inch l1 is rated at 720m/hr

8 inch a1 is 795 m/hr, so yeah the 8 inch will be running slower for the same extraction, by around 10% ...ish

Cheers badbillybob, i reckon a 4db decrease cant be bad. As @Owderb mentioned its a bit of over kill but i might get away with running 8inch A1 at 75% so quieter still! 

Thanks again
