  • Works
Size: 4 Inch Inline Duct Fan ZFP124A01 Color: Black
Nice fan for the size. It moves the air. I cut this in my wall up high behind my wood stove to help push heat. It works great and its silent

  • Powerful little fan, for good price.
Size: 4 Inch Inline Duct Fan ZFP124A01 Color: Black
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

  • Works good, but id get a higher cfm unit.
Size: 4 Inch Inline Duct Fan ZFP124A01 Color: Black
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 Color: Black
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.

  • Disappointed
Size: 4 Inch Inline Duct Fan ZFP124A01 Color: Black
This fan, even on high, has very little air flow and almost no suction. I'm trying to better exhaust a tabletop laser engraver and thought this would be an upgrade to the original fan in the enclosure. This duct fan has less power than the little "computer style fan" that was used previously. Very disappointed and will be looking for a more powerful option. This fan was a waste of time and money. Look for a better fan if you actually want to move any amount of air. ... show more

  • Great for a small grow tent.
Size: 4 Inch Inline Duct Fan ZFP124A01 Color: Black
5 stars so far. Smaller, lighter, and much quieter with plenty of pull for my 2 x 2 x 5 grow tent.

  • Nice air flow, good design and fairly quiet
Size: 4 Inch Inline Duct Fan ZFP124A01 Color: Black
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.
