AC InfinityCLOUDLINE PRO T10, Quiet 10” Inline Duct Fan with Temperature Humidity VPD Controller, WiFi Integrated App Control - Ventilation Exhaust Fan for Heating Cooling, Grow Tents, Hydroponics

This the second AC Invinity T10 I have bought and is one of the best products I have ever seen or bought.The first attic fan worked so good, I decided to add a second fan to move even more air. These fans are quiet and move a lot of air. The fact that it has a controller to allow automatic on and off functions makes it perfect for the application it is being used for. Now I have a spare controller, since the second fan is being controlled by the first controller that came with the first fan. Each controller has the ability to control two T10's. Incredible high quality packing. You know the product is going to be great when you see the packing. Fan has 10 speeds to choose from and the controller "ramps" the speed up and down when the fan motor is turned on. Very COOL. My unit has no vibration at any speed. When you put your hand on the main housing, you can hardly tell the fan is running other than the fact that you are moving a lot of air and you can hear that when running at higher speed. At lower speeds, the fan is super super quiet. Will be looking at other products made by AC-Infinity. Hummmm. Love these products to much, maybe a third T10 will be coming soon.

I love these fans. They work great. I have it connected to a matching carbon filter using flex duct. I then have the flex going out through one of the tent utility holes.The only thing I'd say is to be careful when buying these because mine came with a 69 Pro instead of a 69. Check what you get. They were extremely amicable about it and easily worked with me, but just take a look to make sure.Great service and great fan. Works very well with the 69 Pro.

Great fan surpassed what I was looking for

This is the most efficient fan that we have tested in our passive solar green house. We can set this to 4 and it only draws .48 amps. This still give the 320 CFM that we require for 24/7 use. At full speed we can replace the air in our green house 30 times an hour. We are very happy with the performance.I would like to add after a year of fairly active use through the winter spring and summer, the fan failed. The controller would no longer recognize the fan and it would not turn on. I contacted support and Isaac is sending another fan and a shipping label for the old. If anything will convince someone to buy this fan it should be customer support. Awesome fan supported by an awesome company.

This product works as advertised: it's pretty easy to install, has a good controller, and is reasonably quiet at the lower 2-4 speeds (a bit too loud at high speeds, but that level of power isn’t necessary anyway). But be aware of limitations if you are considering a duct fan:1) When the fan is off, it actually significantly restricts the flow of air though the duct. I wanted to use it for air conditioning routed upstairs, but not for heat (I get plenty upstairs!). So in the winter, it's off and it restricts flow, which is OK for me, but may not be in your situation.2) If the controller becomes unplugged, the fan just goes into max speed mode, very strange and unfortunate. It should just stay off.3) For me, I wanted it to come on only during air conditioning, but it turns out this is difficult with a temperature probe because when the AC is on, the temp isn't too different than the ambient temp at night, so it can come on then too. And then of course in the winter, I have to turn it off. I kind of think I just need to wire it to my furnace and have it come on whenever the AC mode is actively running and dispense with the temp probe. However it doesn’t have any documented method of doing this, I may have to engineer my own solution. If they provided two temperature probes so it can come on based on a differential temperature (inside the duct is 10 degrees lower than outside for instance), that would be much superior, or provide a way to wire directly to the furnace “AC active” trigger.If these limitations aren’t important to you, then this is a fine product.

I admire the quality of the product, whenever I turn it on at any time of the day or night it is always stay online wi-fi and Bluetooth. I do not know what kind of technology is used here but it is super. My smart switches of one very famous company. $ 399 - $ 499 glitch and reboot at least once a day. After 7 months of use I can make any wind speed in the house ))))) from anywhere in the world. This company is waiting for a very big success, no doubt.

We moved into a condo with one zone HVAC. Two bedrooms furthest from the air handler were hotter or colder than the main living areas and the thermostat by often more than 5 degrees. I was able to install this in a hall closet where the duct system was in the ceiling. To date I have only used for air conditioning and I am very pleased with the results. I had to play with the temperature settings for when the probe activates and deactivates the fan, but it was relatively simple trial and error. I operate at level 6 and it is more than sufficient. The noise at the unit is louder than in the bedrooms but In the bedrooms it is no louder than the sound of air coming from the vents nearer to the air handler, maybe even somewhat less. I like that as it activates, it slowly rises to the level 6 speed so it isn't abruptly coming off and on. You may not need a unit this large but I had 10 inch flex duct so it minimized the amount of adapting required.
