AC Infinity CLOUDLINE PRO T4, Quiet 100mm Inline Duct Fan with Temperature

Excellent quiet, very quiet fan. Lovely bit of kit. But it's controller can be very dodgy and common problems with the humidity and temp controller run together, of it turning extract off if humidity low, both fans in fact, or start stopping, etc. So they released, hey presto, and NEW Fan Controller, because this one is pants. Get the S4 instead and an S6, or 2 s6Cloudlines if you have the room, and buy the new smart controller. Sorry I got the T4 but i needed a silent fan, so just run it dumb. There were no S4s as theyre as rare as rocking horse poo poo.

Amazing product, and it arrives with the new Controller AI, not the one displayed in the picture, so just a heads up. It's the newer and better model and provides lots of amazing functionality, and also looks better. The fan is great at extracting air and keeping humidity low in my basement, and I love that I can check the stats on my phone and see how it has been performing. Also, being able to control it from anywhere in the world is very useful as long as you connect the controller to WiFi. Noise can be a bit loud on max airspeed, but that's expected. Anything below 7-8 is very workable. I'm setting it up as a dual system with a blast gate and splitter for humidity control, and also as an electronics fume extraction system, which is great for that purpose. Controller sticks onto magnetic surfaces so I did not need to mount it and put it on my metal garage shelving and placed the fan unit on the top shelf. It comes with very high-quality cables, and the packaging is also very well thought out; each thing is easy to find. There is endless functionality on the app, and you can customise and automate it through a variety of sensors and cases such as RH, temp, etc. Highly recommend it for anyone who wants a good quality and well-made inline fan that has all the features.

For me the ac infinity fans were a game changer, got my environment dialled in just how I need it and with ease to, I purchased an s6 and a t4 reasonably priced I might add, they work perfectly together! These fans are great quality and I was even more pleased when they already came with a connector attached to a U.K. plug! Overall 10 out of 10 for these fans, hats off to AC infinity, they’re so quiet and just a quality product, I will never use another make again, if you’re thinking about buying one just do it, you will not be disappointed

Had heard a lot about these, and was almost tempted to import one from the US, so was pleasantly surprised when one popped up for sale in the UK. I kept my expectations in check, how silent can a duct fan be right? After a couple of weeks of use I'm happy to say I'm extremely impressed. It basically works exactly how I had hoped. The build quality is excellent, the packaging is excellent, and most importantly, the performance is there. At a setting of 2-3, which is all that's needed in a small environment, you can barely tell its on at all, which is just amazing. At higher settings you'll hear it but it's still very reasonable. I didn't expect to use the auto features on the controller that much but it's actually really nice for keeping the environment just where you want it. Overall can't recommend enough, acinfinity should definitely get more of these available in Europe as they are more than worth it.

I love how customisable this is. The features and add ability this has. Not exactly sure with the other reviews saying they got different controllers I got the 69pro. Not the ai. Maybe it's luck of the draw maybe it's different countries, who knows. But I will say it's a great bit of kit love the fact they sent lots of fixture options and it's got booklet to say and show different options. The only reason why I have given it one less star is because it won't connect to my WiFi because my password is too long apparently. Bit odd but here we are, not too much of a problem as it has Bluetooth but if you want it for controlling away from home it's ABIT of a problem. It's well made and looks futuristic and sleek. Controls have auto settings if your not too sure on what to do... Lots of videos on yt if you need help or you can even ask Rufus on here. I asked what I needed to connect my lights to this and it gave me options and I also asked what was better between this and rival companies and came to the realisation I'm getting this. Over all I will be buying nearly all my stuff from ac Infinity.

Fantastic set up works brilliant and all can be done on your phone to change all equipment values can not fault any of the infinity equipment I have 😬

Brilliant piece of kit. So controllable.

Great piece of kit. Extremely easy to assemble and work out how to use the controller. UK plug already attached. Runs extremely silent on the first few settings. Maybe a little pricey but you get what you pay for

La base per un sistema affidabile, scalabile a piacimento anche con luci di marca diversa, meglio la versione a 6 porte. Acquista pratica con l'app android va benissimo. Consigliatissimo

This is an amazing deal. The controller quality is way beyond expectations. Its extremely rugged with excellent buttons and display. Fan has a special plug not a regular plug that inserts into the controller and the controller plugs in the wall. Extremely long wires and connectors are of high quality so this is built to last. You can mount the controller in the tent unlit or on the wall 20 feet away with 3 brightness levels. The temperature probe is very accurate and you can see the temperate fluctuate as the fan speeds change. Controller has six fan speeds and it can automatically change speeds. As someone else said this device alone is worth the $110. Not going to rate the fan until I have used it for awhile - but new it is also really nice. It is very quiet and powerful and certainly pulls good on a carbon filter. I have mine mounted vertically with 1 rigid 4 foot length of duct coming out the top of the tent like a chimney to max out the CFM. If you see no updates everything is going great. For now, I am extremely happy and would be if it was twice the price. UPDATE: 5 Weeks on 24/7 still excellent. Decided to just set it to the 3rd speed and it sucks in the walls of my tent. UPDATE: Totally stopped working a few weeks later so I returned it and replaced it with the same unit. Have had no problem with second unit for 6 months now. This fan is quiet but I would not pay too much of a premium for this as other fans much lower priced will work just as well.

Ich habe das Problem das ich das Zelt nur ins Schlafzimmer stellen kann. Mit meinen vorigen „silent“ fan war ein schlafen ohne Ohrstöpsel nicht mehr möglich. Der ac infinity Lüfter ist bis zur Stufe 3 von 10 so leise das auch ein schlafen ohne Ohrstöpsel möglich ist. Mein Lüfter wurde mit den 69 pro controller versendet, nicht wie bei anderen rezensenten nur mit den normalen 69 controller. Dadurch kann ich die Abluft auch problemlos von unterwegs einsehen und einstellen. Ich finde die Programmierung der Zeitschaltung unnötig Komplex aber hab ich auch hinbekommen. Zum Verkäufer: Ich habe beim Verkäufer my deep store gekauft. Der Verkäufer war so nett und hat mir vorm Versand mitgeteilt das ich zum Betrieb einen Us auf Eu Stromadapter benötige( hier reicht ein einfacher von Brennenstuhl hier bei Amazon für ~ 2,49€ erhältlich aus) Bei der ersten Lieferung kam es bei Dpd zu Problemen (Sendung verloren bzw. Sendung defekt). Der Verkäufer hat mir Angeboten entweder eine erneute Sendung dieses mal per Ups oder eine Erstattung des Kaufbetragd anzubieten. Ich finde den Service des Verkäufers ( my deep store) super alleine dafür 5 Sterne. Der Lüfter ist bisher auch top, ich hoffe dieser hält lange.

Trabaja bien y el app funciona con Bluetooth (no con wifi). Es silencioso solo en los niveles 1 a 4

Honestly this things super quiet & i don’t even notice it running in my tent setup. At full blast this thing pulls a lot of CFM & will clear the area in minutes! can be ducted & hung easily in setups!
