iLIVING 30" Wall Mounted Shutter Exhaust Thermostat Control-2 Speeds Vent Fan For Home Attic, Shed, or Garage Ventilation, 5088 CFM, 7500 SQF Coverage Area, Silver (ILG8SF30V-T)

Fans are awesome, would give a 5, if the framing was internally sealed. I took the shroud and motors off and sealed all of the inside framing, and made a lip on the bottom to keep any rain runoff from backing into the building. Other than that they are well made and work great.

Old exhaust fan died. New exhaust fan is better than expected. It’s not quiet. But it does work very well.

I am waiting on UPS to pick this up for return. Nothing wrong with it just isn't what we were looking for

Vents the greenhouse like a champ! Very reasonable amp pull for the size. Efficiency was my main concern.

This product is just what I needed. I’m using it for ventilation in my barn which about 1500 sq ft. It’s all that is advertised.
