Review: Quiet and pulls the air! - Put this in vent in bedroom of camper to pull the cold air better. Works GREAT! Ran cord across the ceiling to plugin. Makes a big difference on the air coming from that vent. Plan to get another one for the other vent. Quiet and pulls the air.
Review: Decent inexpensive fan but doesn't move a lot of air - Its a decent little 4" fan that seems to work fine and doesn't make a ton of noise. However, it doesn't move much air, just be warned. I bought it to cool a 4 foot x 4 foot closet that contains my 125k BTU combi boiler for hot water and heating in my house. It brings in outside air directly through an outside wall and even when its 20 degrees outside it still can't even keep the closet at 70 degrees. And thats a 4x4 foot closet. It just doesn't move enough air.

## Features

I am using this to vent a small laser enclosure. It doesn't move a lot of air, but it is adequate for my purposes. It is quiet also.
