Dayton exhaust fans.

I was looking to get this for my venting/filtering for my flowering cab.

Anyone use this fan? Basically I wanted to get a comparison (sound levels/performance) compared to the other fans that are 2-3x the price.

thanks

They are loud, the vortex type produce more volume of air and way less noise.
