Grow Room Need quality exhaust fan for 3x3

[idiopathic neuropathy]

Hi all....I've been burning through exhaust fans(2) in the last year in a 3x3.

Any one have experience or can recommend a good one ? If it comes with a speed controller all the better? I dont mind paying for quality, tired of wasting money on exhaust fans.

Thx in advance,
Id

I use the TerraBloom 4 Inch 160 CFM inline fan and it works like a champ. $80 which is not too expensive, it's very quiet and has a variable speed control.

Vortex inline fans are of good quality and my favorite. I utilize variac controllers with my inline fans and they my favorite piece of growing equipment.

The AC Infinity Cloudlines are also getting to be pretty popular. Variable speed with temp and humidity controller as well.

I've used 4"centrifugal fans for years...mine are the heavy metal ones, tough as heck...but notice a lot of them now are plastic or some light weight stuff making me wonder about longevity.
IMHO, I'd buy the metal casing fans or a well reviewed alternative.
