CLOUDLINE T4, Quiet 4” Inline Duct Fan with Temperature Humidity Controller, Bluetooth App - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics

AC Infinity products never fail to impress - I purchased this T4 In-line Duct Fan for Marine use - The design, efficiency and low noise combined with the interface functionality is awesome - I have since purchased additional smaller fans for other applications

Very good product ! But I gave 4 because they didn't offer me the opportunity to choose the plug socket (I bought an adapter from US to UK ) no problem with the voltage (100-240V).

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.

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.

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
