VIVOSUN Inline Fan 6" Inline Fan

Headline: Quiet Powerhouse – Perfect for DIY Solder Fume Extraction Rating: ⭐⭐⭐⭐⭐ I bought this Vivosun 4" (100mm) inline fan for a custom solder fume extraction project, and the performance is impressive. I’m currently running a 6-meter ducting setup (3.5m intake and 2.5m exhaust) and even at just 60% power, the suction is phenomenal. The fan has enough static pressure to draw smoke from a soldering iron easily from 10cm away, even without a hood attached yet. It’s surprisingly quiet for its 190 CFM rating; I can talk over it comfortably while it’s running. The build quality feels solid, and it handles the resistance of long duct runs without stalling or struggling. If you are looking for a capable fan for a workshop or hobby setup where you need high suction without the jet-engine noise, this is the one. Pros: • Extremely quiet operation even at higher speeds. • Strong static pressure—pulls smoke from a distance. • Compact 4-inch size fits standard 100mm flexible ducting perfectly.

Muy mal, plásticos baratos, a bajas revoluciones se acelera solo y hace ruidos extraños, lo devolví. No lo recomiendo

Der Ventilator ist super ,hohe saugkraft und relativ leise, meine Frau ist überglücklich

This fan has been running 24/7 for 6 years with absolutely no issue and it's still as quiet as the first day. Must have excellent ball bearings in it!

So, I'm using this fan as part of my custom built ventilation system in my basement room converted to a cigar room. I use it to suck the cigar smoke out through the window via the 6 inch hose and some ducting that goes out. I use it in conjunction with a duct fan that's hooked onto the HVAC ducting that acts as an intake fan for the same room. What I like. 1. The speed controller comes attached. No need to purchase one separately. 2. Durable. I had a mishap where I accidentally dropped it from 7 feet to a concrete floor. No problems, turned it on and fired right up. It's plastic on the outside, but the fan itself has some good heft to it. 3. Powerful. This thing cleans out a room fast. You can watch the smoke going from the cigar a good distance away in the room as it goes right to the area of the fan. What I don't like: 1. This thing is loud. But, that's the compromise. If you want a proper fan that will do the job, noise will be on the table. That all said, it's not loud enough to drown out conversation or music on a small speaker in the room. Further, it's powerful enough to run on low and still keep the room clear with one or two cigar smokers. In all, this being part of my ventilation system saved me hundreds of dollars by not buying a rabbit, or any other overpriced smoke eater. Good price, quality fan.
