Be sure to size the ducts properly with ASHRAE and SMACNA standards. There are online duct size calculators you can use. If you know the cfm requirement and what kind of duct to use.. just input it and get the proper duct size for your application.
Wrong size of duct = slow or worse no air movement.. or can be noisy ducts. Also, you will not meet the proper air change in the room for proper ventilation.
Topic: Hurricane Fan to Move 1000 CFM and Ventilation Questions (Read 401 times)
It's me again. UPDATE: 2 of 5 Avalon 741 miners up and running just to learn. I tried 3 and basement became ridiculously hot, so I will wait until my wine closet is ready and properly ventilated before I get all 5 miners going. I'm now working on ventilation while I wait for the electrician. Since I'm putting 5 miners into a small space, I have decided to go with this method: https://www.youtube.com/watch?v=317wqakIKx8 (if you don't want to watch, my short description is below).
Basically, I will attach insulated duct work to all 5 miners. I will run those 5 ducts into a larger tube with a hurricane fan on top. The fan will push the hot air out of my house. I'm reluctant to use PVC as the "larger" tube because (from what I've read) it can deform at high levels of heat. Anyway, here are my questions:
1) Does anyone have experience with this Hurricane fan? Do you like it? How noisy is it? http://www.ebay.com/itm/Hurricane-Inline-Fan-12-in-1060-CFM-736590-Commercial-Grade-High-Performance-/302461946006?epid=1007520736&hash=item466c230896:g:v9MAAOSwVaVZxCny
2) For my "main tube" I was thinking of duct taping a bunch of y-joints together (http://www.homedepot.com/b/Heating-Venting-Cooling-HVAC-Parts-Accessories-Ducting-Venting-Transitions-Connectors-Wyes/N-5yc1vZc5hq) and then running my 5 insulated miner ducts to the y joints? Is this a good idea?
Thanks in advance for you thoughts.

PVC has limited heat tolerance, which is why it's limited to use on COLD water distribution.
CPVC had much higher heat tolerance, it's rated to handle hot water - but it might STILL be marginal at the temps that come out of most miners today.
4000 CFM is severe overkill for 5 Avalon 741 units - something in the 1000-1500 CFM range would be PLENTY, unless you plan to add a LOT MORE MINERS to that space.
I use two of these to vent the air from my 5 Avalons:

Together they should move 8k CFM on the highest settings, or 4k each.

Holy crap! Isn't that overkill? Maybe you are the planning for a major expansion? Also, how noisy are those fans? I'm trying to design a small home basement mine.
I don't know if its overkill - I have the 5 avalons, an eBit, and some S7s running - and have some S9s on order. Mining requires always expanding your hashrate as difficulty goes up.
The fans are pretty noisy - about 90db. About the same as running a vacuum cleaner (or two). I run my miners in a warehouse, and they heat the rest of the warehouse.
