AC Infinity CLOUDLINE S8, Quiet 200mm Inline Duct Fan with Speed Controller - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics, 8-Inch

Bought it for a DIY Air Purifier, and it's extremely powerful on max settings. Looks good too, it's well made. I'd order from them again when I aim to get a humidifier.

This is crazy powerful, it will literally take off if not held down. It has single handedly resolved my heat problem on my rig. Absolute must buy for miners. Quality is excellent, noise is acceptable. A+

I read the reviews before buying, and i've got to agree, this fan is very powerful on full power, even on the low speed, there is very good air flow. its very quiet on the low speeds, came fitted with a UK plug.. very happy with this purchase.

Did not come with a remote as said in ad and is the speed is set to max so can’t actually use till I get a remote to control it but over all a great product

thumbs up

I was planning to use the unit to boost air flow across a HEPA filter (got excited about the "booster" part in the title). I expected more airflow at the output than I was getting (air flow reduced about 3-fold at max setting). I will keep the unit b.c. it is affordable, and it has speed control; will use it to test 12" panel filters. Will need to get a centrifugal unit to use as a booster in an HVAC duct.

These are a serious bit of kit for the money. Gave 3 star for noise as they are noisey but doubt you will find one out there that isn't. It sounds like a jet engine about to take off before you even get to full power. I've brought the ac infinity silencer to reduce noise and its still to loud if want to take it above the 3rd power setting. But for me I find setting 3 more than enough for a 2mx2m set up. Would definitely buy again and would definitely recommend. Would also recommend buying silencer aswel though

Amazing

Du bon matériel bien fini, avec prise française. Très puissant !

Pour diverses raisons, j'ai laissé cet élément dans son carton depuis sa date d'achat (il y a 2 ans). Or aujourd'hui je découvre qu'il est équipé d'une prise américaine, donc inutilisable en l'état . Trop tard, évidemment, pour le renvoyer... Je vais essayer de bricoler quelques chose, mais soyez avertis!

The fan works great and has a wide range of performance that allows you to run this thing at any speed between silent and very loud. I use mine as part of a DIY ventilation system for an old apartment and it provides loads of air movement and static pressure. At full blast, I measured its power draw at 165 watts. The fan is notably very efficient and can still move a surprising amount of air at its lowest speeds with around just 5-10 watts of power usage. (Though you won't be ventilating a whole space at that level.) One thing to seriously note though: This fan can be a real safety hazard if not used correctly. It should really have some feature to kill the power easier since at full blast this fan will happily consume any nearby debris and probably result in injury if you were to get your hand in it. There is no built in grill or safety screen. The controller allows for the selection of 10 speeds, but requires you to loop through to the highest speed before it will shut off. Additionally, when you remove the controller by disconnection, the fan defaults to FULL power. I had an incident where the fan swallowed a bag of small screws and I had to hastily chase down the power plug in order to shut it off. I guess as a testament to its durability though the fan didn't seem to suffer any damage. I have since included a shutoff switch in-line with the power cord.

I use this as the fan in my workshops welding ventilation system. The sound level is very reasonable given the considerable flow rate. I do wish the control had a simple on-off instead of a single button that cycles through the 10 speed levels. I have to tap the button 10 times to cycle the flow back to max each time I use it. But overall it’s a high quality item that I’m glad to have.

There is no planet where this thing is 38db. MAYBE on its lowest and most useless setting.. but by half speed its extremely loud, and at full speed it might as well be a jet engine. It is really powerful though, and does a good job moving air.. but i bought it cause it was supposed to be really quiet, and its not. I'm sure others are louder (I have others that are louder), but the 38db label I feel is misleading. Almost every fan is quiet on their lowest setting. One other plus is, its realllly light. Not in a cheap way. I've had others that weighed twice as much. So mounting it shouldn't be a problem for anyone.
