    • Powerful little fan, for good price.
Size: 4 Inch Inline Duct Fan ZFP124A01
Powerful, fairly quiet, simple to setup and use. The speed control is great, works perfectly to help increase my electric clothes dryer's efficiency, went from having to run my dryer for several cycles, to only needing not even one entire cycle for a fairly large load of clothes and towels. Good buy overall! ... show more

    • Skip this cheap crap.
Size: 4 Inch Inline Duct Fan ZFP124A01
Review Image by Martin Taylor
Product arrived damaged. Cheaply made. Completely useless out of the box. Update: Seller was solid and provided refund after 30 day window. Changed review from 1 to 3 stars. Fan made mostly from plastic: I would not purchase fan again. I would purchase again from seller.

    • Nice air flow, good design and fairly quiet
Size: 4 Inch Inline Duct Fan ZFP124A01
This fan really pushes some air for its size. Adjustable to meet my exact needs and works beautifully. Motor noise is not bad at full speed and barely noticeable at slower speeds.

    • Works good, but id get a higher cfm unit.
Size: 4 Inch Inline Duct Fan ZFP124A01
Quality, well built product. Works for how i use it. ( venting lead fumes for a lee melting pot for reloading). But with a 4 ft section of dryer duct attached to. It doesn’t move as much air as i had hoped. If I were to do it again I would have opted for a higher cfm unit.

    • Great fan
Size: 4 Inch Inline Duct Fan ZFP124A01
Been this as an exhaust fan for my 3D printer for 3 months and it works great so far. You can hear, but it’s not really any louder than the p1s fan on its own. It seems to effectively pull the fumes out of the enclosed printer.
