Review: Fantastic vent fan. - This is a fantastic little device. Stylish and well-made. Even on high it is very quiet. I wanted it to ventilate my laser engraver enclosure. I wasted $40 on a cheaper fan, whose cfm capability was claimed to be double what it actually moves. This one actually pulls a vacuum in the enclosure. Hopefully it holds up to pulling smoke and not just air. Very satisfied so far.
Review: An improved inline fan - Installation was quick, works great, noise level is quieter than past models.
