CLOUDLINE PRO S4, Quiet 4” Inline Duct Fan

パワー感は、どうかな？ と、いった感じです。

-It comes with the right power plug for EU(for 220v), even if the original images of the product don't show it(i think they are old), it looks like in the past wasn't the case because of others reviews, but now it comes with the right power plug -The cables are long, i mean, looong(power and controller cables), 2,5 meters for uis cable and 2,3 meters for power cable -I took photos of the manual only so you can see: +installation in different scenarios +cleaning +you can see its an actual useful manual +and the warranty part makes me feel like they really care -It comes with every screw, strap and little thing you need to install it in all possible scenarios(see the photos) -If you want to get noise test you can go to amazon.com(eeuu version) and see the videos on the reviews, my phone mic is trash so I wont do a noise test, but I can tell you that at level 1(it has 10 levels) makes 0 noise, at level 5 its the maximum I can deal with(and need) and above looks like its for scenarios where you really need to ventilate and dont care about the noise, so it gives you options, from 3 to 5 in my case is enough(I will never go above most likely) -I like the philosophy of "its yours, you have the control: you can fully open it(normal screws), you have all these intensity levels(from 1-"it barely moves" 2-"quiet and performant" to 3-"hold on to something, this airplane its gonna liftoff", you have a detailed manual, you have long cables, in the box you have all needed screws and little things" -btw the fan is exposed...not a bad thing, its made for people that think a bit

Sorry I didn't take pictures of the unboxing because this thing is packaged so well in terms of padding and just an overall esthetic that you get when the packaging wows you. Phones are a great example of this esthetic and this purchase was the same - just like "Oh wow...". I probably did not need this nice of a fan, but after reading the reviews, I thought it might not be a bad idea to step up to something that was so highly praised. And the reviews are not wrong, this is very high quality at a reasonable price. It is powerful and very quiet, although noise is not something that is going to bother me in the greenhouse. As others have noted, the installation felt weird because you need to take out the middle bit to screw down the base, but it makes sense it would work like that. The clamps are quite sturdy and fancy looking. They work well to snug up so that there won't be any vibration. Using it in my teeny little greenhouse, just one day's worth of experience. It didn't bring down the temperature right away, not as much as I hoped anyway. The little greenhouse that could goes well past 100 degrees some days, when it's not even hot outside. I don't have an inlet (yet), but I do have a gizmo that raises the roof vent when it gets hot. Oh well, TMI, here's a pic. Nice fan, buy it!

This fan is fantastic in build quality and functionality. If you need to move air this is a great buy at a great price compared to others. It is super quiet and the long chord on the controller is a nice feature. It looks great and you can tell by handling it that it is a quality made fan. ***UPDATE May 2021*** This fan has worked so well for me non-stop for 7 months that I needed another one and I bought the exact same fan. In fact, I started out cheap, and bought a different manufacturers fan first to save $30, and it was so loud that I returned it ASAP and bought another one of these AC Infinity fans. Two things about it you can't beat, for a 4" it moves air very well. And second, it is the quietest fan I've found of this type. Some may say it gets loud on high settings, it's moving air, it needs to make some noise. But you don't hear the noise of the motor, you only hear the noise of fast moving air. Love it. I'll never buy another brand again.

Me llegó a tiempo, excelente extractor de aire, viene con todo lo necesario para su instalación y con folleto, volveré a comprar sin duda, gracias AMZN
