i dunno where you are, but every grower in the uk (that i know lol) seems to use RVK inline fans, they are powerfull and designed to work in negative pressure ducting, so no worries about that 4 meter duct you have on either end. reasonably quiet to. they come in a range of sizes from 4 in ch upwards, so thres one for every application.
i personally have found them to be easey to set up, reliable, and quiet ( provided some simple steps to elliminate vibration are used ) its not the fan itself that makes the noise its the vibration against whatever you mount it to.
they are available from many places, but this link shows most of the range.
i have the 8inch(i think) version, and its more than enough for my needs 4-8 plants, 1x400w hps
i could probably get away witha smaller one.

If your don't need to be stealthy....20" box fan $10 and 2000 cfm. Works great for me.

i'd like to know more about this 20$ fan, i paid 60$ for my inline duct.
Home Depot has a lot of different fans including the ones you're looking for

Invision, if you are wanting a centrifugal fan the best price I have found has been Maryland Hydroponics: $148 for a 6" 465cfm Vortex. They've got good prices on Can carbon filters too, and the cheapest cool tubes I have ever seen at $59.

Its just a standard box fan....every hardware store should have them. Well harder to find them in the winter.

yeah i seen those fans at maryland hydro, do you think a squirrel cage fan would be just as good i seen a 465CFM for 89.99

Thats a pretty serious squirrel cage and not a bad price either. I'm not an expert on fans by any stretch but my experience so far has been that the centrifugal fans are better at dealing with negative back pressure (longer ductwork runs) than the squirrel cages which seem to be better at "pushing" air rather than pulling it. I have no clue why that is - maybe if I duct taped the hell outta my squirrel cage it would seal air leaks or something but I try to use about 15 feet of that flexible ducting crap and the squirrel cage is hardly pulling on the intake but has plenty of air output so it's getting in there somehow - I don't think all the ductwork helps it at all but my centrifugal fan has no problems with it...that thing moves some serious air.
So the bottom line is: how do you want to use it? Push: Squirrel cage is fine Pull: Centrifugal all the way.

i need it as a exhaust fan for my cab and maybe run a scrubber off it too, there may be 3 feet of duct work from the cab to the scrubber will this work the centrifugal fan is over 50.00 more i dont want to break my wallet to much.

I think with that short run it will work fine and give you some coin for more beans!

yup my 1st grow was a success and its really decent for bagseed got everyone baked so far and taste amazing, i already know what the next grow is and it will be NLxC99 it looks awesome.
going to order that fan and flange tommrow then i need to get back to growing its still very dry here, another question..........
i run 2x150watt hps would going to a single 250watt be worth it or will my coverage area be better off with the 150's the cab is 3x2x4.
help me find a centrifugal fan
i would guess you wont gain anything by swapping for a 250w, apart from using a bit less power, with 2x150 theres more light and more coverage
help me find a centrifugal fan
the thing that will improve will be the penetration tho from the 250watt it has 18" canopy penetration where the 150 have 8-12" and the lumen out put would be the same.
i dunno i just think a 400would be too much power in such a little cab i would need a cool tube no doubt about that.
help me find a centrifugal fan
BTW Invision, where was it you saw the 465cfm fan for $89. I may need another smaller one if they've got a full line.
help me find a centrifugal fan
right my friend

on sale right now a 600CFM for the same price just mmake sure you get the 6" flange with it so its ready to rock and roll out the box
help me find a centrifugal fan
on another note i could really use some advice if switching out to the 250 would be worth it, my plan....hopefully.....is to start a mother cab with one 150watt light and a cloning cab with the 2nd 150watt i have.
hmmmmm choices

hey invision ,
i myself use hurricane fans and love them . esp. the 10 yr. warranty . they're quiet , move tons of air . they're kinda pricy but like everything in life you get what you pay for .
peace

how many plants are you planning on flowering at the same time?
might be an idea to have the clones and the mother under one light, and the flowering room with the two lights
help me find a centrifugal fan
i believe my box can support 4-6 plants but 6 plants may be getting too crowded so we will say 4 plants to be safe,ill just veg the plants longer if needed to fill in the void area's.

Unless you have feminized seeds you should start more babies with the knowledge you'll probably weed out a male or two in the process.
help me find a centrifugal fan
i would be tempted to try a 150 for clone/mother, and a 150 + 250 in tthe flower room
my idea being, you just want the clone/mother room to be ticking over slowly, whereas the more light the better for flowering, plus with two lights, youll be able to rotate the flowering plants according to size/maturity..gives you a bit of flexibility
