Fijne stille ventilator die je harder en zachter kan zetten. Werkt bij mijn CO2 laser perfect

The brand is one of the better manufacturers selling to the general public and the vendor was very supportive and provided prompt service. I would buy from them again and recommend the inline fan without hesitation. It’s quiet at lower settings and works without issue.

DAY 1: WHY I BOUGHT THESEI bought these hoping to find a 6" fan that could move some air gently, without causing the sound and fury of a small cyclone in my recording studio. With voice over work, extraneous noise is a problem. So is heat, and air!, because VO rooms are usually completely closed off the the outside world. They get hot and stuffy without proper air flow.This is the answer. I have tried 6 different claimed-to-be-quiet fan solutions via Amazon and YouTube reviews... this is unequivocally the best for my situation.I unboxed and hooked one of these up (not to my room, because that will require some ducting and electrical changes) in an untreated echo-y basement room with a hard tiled floor. So no mounting yet, no ducting yet, just the fan on the floor with its 10-level USB-C controller, and me holding my iPhone running the app "SPLnFFT" noise meter at about 12" above the center of the fan, airflow running unimpeded from left to right on the floor, The iPhone was held level so I could read the display.Here are a few hasty values.Starting point: Fan at 0 = 30db (A) This is the room's noise floor when nothing is turned on. The meter terms this level as "Almost Silent".Fan at speed 1 = 37db (A) The meter calls this "Very Quiet".Fan at speed 2 = 45db (A) The meter labels this "Quiet."Fan at speed 3 = 53 db (A) "Comfortable"Fan at speed 4 = 60 db (A) "Moderate"ASIDE: Note that these levels are purely "in the moment," not carefully measured. Use these approximate numbers as a rough estimate only if you are similarly seeking a quiet, controllable fan solution. I did "round off" to the nearest dB, so 37.2 became 37.Keep in mind I intend to use 2 of these fans, 1 to send fresh air into the booth from floor level, and 1 for pulling warm air out of the booth above eye level. I don't want a wind tunnel, simply fresh air moving through the space via insulated, flexible ducting to help keep the air flow noise reduced as it travels into and out of the booth. I anticipate that once installed, I can record spoken/sung material without concern for air noise.Even at speed 1, the air flow felt pretty good. At the next higher settings, it grows noticeably stronger. I only ran through speed settings of 0 to 4, because at 4, I figured I was getting to "you're gonna hear this" territory and decided not try any higher settings. I would not record with air flow noise. But I did step though the rest of the settings, because the fan controller only increases the speed (no going down, only up) until the step after 10, which is off, so I got hear and feel those levels even though I was not interested in measuring them.A pair of these fans will clear the space pretty easily.THE FUTURE: AFTER THE INSTALL, and LONGEVITYI plan to return and update this first-look review with genuinely measured results once the booth is complete. That will likely be another few months because... life, family, and holidays. And if anything fails (controller, fans, whatever) I'll update this then, too.

Good quality. Very quiet.

I really like this unit, it's powerful, it's quiet and the noisiest bit is the airflow. I am using it to blow air into a portable generator enclosure and the first thing I learnt was to make sure it has a good plenum to draw. I also found it works better if the outlet is not too close to a bend or obstruction or the back pressure affects it. But all of that is good HVAC design practice and for the money its very powerful if you wind it up.

All went well except that I did not receive an AU wall socket cord in this order. Thats' a bit of problem because we do not have UK wall sockets in Australia and this order was made via Amazon AU, so one would assume they would add AU cord. Amazon is impeding to contact the AC Infinity AU reps directly so I can not get them to send me the correct AU-compatible wall socket cord. What should I do? I already got $25 gift card from Amazon as a "sorry we messed up" but that's not helpful because I am still unable to use the purchased device.
