[BeanZyBoo]

I've been looking for hours at all these fans and getting no where
fan will be taking heat and smell out through active carbon into loft, 1.5 meter of duct MAX
space is close to 3x4x8ft or 0.9x1.2x2.5m
want something thats going to do the job of removing heat and mainly smell and create negative pressure. i just dont want to spend money on something not enough or too powerful for what i need, please help a fan noob

i've been looking at those, well tbh i've been looking at em all, thos rvk's look good but just dont know what size i would need,
i know how much air i need to move in the space but i dont know how much air i need to move to be effective agaist the smell and heat, thanks for the reply

ok i 'll just ask this 1 question, is it possible to have a fan too powerful? that will answer all my questions thanks

For a room that size, I'd get a 6" a ventalation from home depot for 30$. warrantied, cheap, and pushes air. That's just me though

 

[BeanZyBoo]

Ok bro with fans you CANT have too much...Get the biggest fan you can afford and if its too much you can just buy a cheap fan dimmer switch will allow you to control the speed of the fan for your needs.. More air is a GOOD thing and like i said yu dont want to not have enough air better to buy more than you need that way you can grow into it if you want to upgrade or expand your grow....I use an 8inch fan for one 1000w light and i wouldnt go back to a smaller one thats for sure.....

Also get a good quality fan... Not a cheap ebay one.........I personally like " ellicent" fans they are very powerful for how queit they are.....Just remember fans are load so you want some sort of sound damping weather its a silincer or a carbon filter or both need somting to quit it down if noise is an issue....I live in an aprtment and i use a 4foot silencer contected directly to the back of my fan lol i know its a bet over kill but i want it QUIET dang it.

Other good fans are "vortex" and " can- fan" i would only get one of those 3 brands and if your going to use a 1000w get an 8in fan if your going to use a 600w you can get away with a 6in fan....

4x3x8 space is 96 cubic feet. i personally have 112 cubic feet of space and i use a 4 inch High Output Can Fan. They are relatively quiet for the amount of air they move. I believe it pulls about 155 cfm so it should be enough for your space if you just add a couple fans for circulation. Remember everything you add in the path of the fan (ducting, filters, hood) will decrease the cfm so you need to compensate for that. Lots of people suggested going with a 6" can fan, but I found it to be too much.. and it sounded like a small airplane taking off..
