Very well made. Does outstanding job
Size: 6 Inch
I got this to use to vent the air from my WeCreat laser, I had a 4” hose setup but it was still allowing a lot of smoke into the room where I have it. I have the hose vented through a window and it just wasn’t enough to pull the smoke out. Boy am I glad I got this, I printed a 4” to 6” adapter and got 6” vent pipe from my local box store and this thing is powerful. Well made, super easy to install and really does the job a lot better. The speed control switch is a plus and it really, really works well for the use that I needed it for. Highly recommend. ... show more

Great Airflow
Size: 4 Inch
I've been using this inline fan for a couple of weeks as the exhaust fan for my laser engraver enclosure, and it's been a noticeable upgrade from the 3-inch fan I was using before. The increased airflow keeps the enclosure under negative pressure while it's zipped closed, so smoke and odors stay contained instead of leaking into the room. For laser engraving, that's made a significant difference. It does produce more noise than I expected, especially at the higher speed settings, so I wouldn't describe it as whisper quiet. However, the improved airflow is well worth the extra sound in my application, and the speed controller lets you dial it back if maximum airflow isn't needed. Overall, this is a powerful, well-performing inline fan that does an excellent job moving air. If airflow is your priority, it's a solid choice, just don't expect it to be completely silent. ... show more

Stronger than it looks.
Size: 6 Inch
Nice little inline fan. the variable speed works good to strike a balance between flow volume and noise. Looking inside it is like a computer fan with added stationary fins but it blows pretty hard. I checked the size relative to some flex duct and solid metal and it is plenty undersized to slide right in. Plan to use clamps and aluminum tape. It will be quieter with flex duct between it and any rigid duct. It is plenty lightweight to be suspended by the flex duct. This is perfect to vent a couple of laser cutters, 3d printers, a welding station, or a small fume hood for painting, etc. I found some very flexible 4" duct that can attach directly to my laser head. I'll have to design a nicer adapter to 3-d print for it. ... show more

Slightly loud, but it moves air
Size: 6 Inch
My computer closet runs 5–10 degrees hotter than the rest of the house, and adding a graphics card for AI work only made things worse. I'd already put in some passive air vents, but they weren't moving enough air on their own, so I picked up this inline fan to help cycle the air around. I got the 6-inch model and the body feels pretty solid for plastic. Turning it to full speed moves a lot of air right away — I pointed it at my face first thing, which is always what I do with any new fan — but it also creates a whining noise that sits somewhere between moderate and slightly high-pitched. Not annoyingly loud, but you'll notice it if you're talking in the room. That'd probably quiet down a bit once it's inside ducting or an enclosure. I run it at about 50–60% in the closet now and that works well. The controller is responsive — easy to dial down without losing much airflow. It keeps the heat from creeping into territory where I worry about the GPU throttling, and the lower speed means I can leave it running all the time without it becoming a distraction. ... show more
