Cheap, efficient, quiet fan/filter combo!!

The ac infinity cloudline t6 is really quiet, they claim the noise level is around 32dba, but in my testing its closer to 40 dba, but that's still super quiet for a fan that can blow or pull 351CFM(s) on the highest setting! Also, in my testing the max CFM(s) is more like 332 instead of 351CFM! And one more thing... I don't ever match my fan size to my carbon filter size because most fans that are the same size as the carbon filter are not strong enough to take full advantage of the flow rate the CF supports and you want to match the CF flow rate as best you can cause it allows for the best filtering well also allowing for a better air exchange rate for your grow area! So for example... a 4" x 16" 300CFM filter hooked to a 6" fan with 6" to 4" reducer, like the ac infinity cloudline t6 set with the speed controller on (6) is a better option than using a 4" fan with a 4" 300CFM filter that only supports 190 - 200 CFM(s) max!

I have fans which on full are 23db and 25db.
Squirrel cage design so the can handle duct and filters no problem.
Its something ive been looking for years and after buying a few supposed silent fans that were 50db I gave up trusting what they claim until I found these.
Mine are from ebay.uk but I know they are just Chinese generic fans and can be found on Alibaba.
Literally my circulation fans are louder, with a speed controller I cant even hear them.

Sweet thanks guys. So I got a remote to lower the power. Also I did some diy stuff to it, helps a little. So I can use a 4'' filter with this 6'' fan? That's good to know. Also I'm looking into the exhaust. I bought some ducting yesterday online, hopefully it's insulated, lol. Didn't realize I needed insulated until after I ordered.
Could you still sort the eBay link? I'm struggling to find them!
