Looking for a quiet in-line exaust fan & Speed controller what would you recomend?

I have a small area I need to ventilate better the size is 4' X 4' X 5', My number one feature is to have a smooth and quiet in-line exhaust fan I assume this needs to be a well made one; also I am looking to get a speed controller any recommendations? -Thanks in advance!

Hi GrnMonStr,

no answer but interested !

i have 2 4inch inline fans and 1 6 inch all by hydrofarm.. a bit expensive but they move air.. at full speed they can be heard pretty well even up stairs,, ive mounted them to studs w/ rubber feet to stop vibrations and put insulation around them,, it keeps the sound w/in a resonable amount.. id like to hear if anyone has a quiet inline fan,, high cfm and quiet,,,,dont know if it exists

I'm using this in a 2.5'x6'x10'H closet. I added another variable speed control to slow it even more during veg. It's pretty quiet. I can only hear slight hum outside the door with both controllers on the mid setting. Running it with a 6'x24' filter through 12' of duct and I'm definitely at overkill status. If I set it to high, it blows stuff around in the next room. On it's lowest setting (without additional controller) it's not much louder than an 80mm PC fan but will still blow your hat off.

HyperFan makes a silenced fan with dimming. Best fan I have found and more efficient. I have 3 in my room and they all draw less than the 8" MaxCan fan Pro I had before.

Well I have to say you guys posted some quality fans that I did consider so thanks for posting and maybe if I had a larger grow area those would be my pick for sure. But since my area is small I ended up buying this one, https://www.amazon.com/TerraBloom-LowNoise-Booster-Intake-Exhaust/dp/B01M2XG0E1/ref=lp_12689076011_1_8?srs=12689076011&ie=UTF8&qid=1499393340&sr=8-8

I originally seen this fan from this cool DIY COB build thread: https://www.rollitup.org/t/250w-cxm22-dresser.942643/#post-13590790

get a hyperfan they are the best

I agree with hyperfan. I have 4x3x5 and 6 inch hyperfan has never been over 60%. Quiet, efficient, and good airflow all at reasonable price that includes speed control.

Good choice on the terra bloom. It's a quality fan, built in Germany. Moves tons of air and WILL pull through a carbon filter great. I can literally use it as a leaf blower.
Thanks for the cred! Lol

Can fan q line. They have a built in silencer and speed controller built into them. Not cheap though.
