suspend between joist with rope type 17 inch bungee cords to take up all vibration. air noise equal to blowing fan.

Just as described and it does move quite a bit of air. Mounted in our crawlspace so do not hear it at all.

I received this one in good condition. The first one I ordered had to be returned because it arrived broken. This replacement is working great, a little louder than I prefer but not bad. Works great in a 7’ X 5’ grow room.

Definitely a huge difference from the Bo-Bo Edition fan that came with the Gro-Tent combo PKG. Only thing I don't like is the remote. It's like no matter what setting you choose it's still balls to the wall and it's noisy as can be. Like example it's on one side of house with 2 other bedrooms I can hear it in living room that's down the hall from it when it's running. But I was experiencing serious heating issues with my set up in grow tent an no lie after redoing my ventilation and intake setup. On the digital thermometer you could literally watch the temp drop when fan was activated. So I'm pleased oh and 1 used for exhaust in a 8x4x6 is plenty. The other one I got I through in the 4x2x6 and it's a slight overkill until I just put 8inch to 6 to 4 adapters on it. Which toned it down somewhat. Lol before the whole tent was sucking in haha

Great item and very fast shipping.

So quiet, I had to check to see if it was running

It's a great fan now I just got it hooked it all up and it's doing amazing

I purchased this fan for my 4x4 grow tent. I do not require cooling, but need a fan to suck out the CO2. I live off grid in a one room home, so I needed a fan that used as little energy as possible and was also quiet. I have not needed to set this fan up yet, but did plug it in to check the noise level. It is quiet, as advertised. It also appears to be well constructed even though it is plastic. I also felt that plastic might be lighter weight than an all metal fan. I cannot vouch for its durability yet, but from what I have experienced so far, I am happy with this purchhase.

This fan works as expected. I use it to exhaust the hot air from my attic, it has been running 24/7 for a month with no issues. The fan is quiet at full speed but does increase in sound when you slow the fan down. All in all the fan works well and the price is right.
