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

I liked the features of this fan, including the speed control. It's a superior design because it has rotor and stator blades inside the housing. This type of fan is quieter more efficient than a simple fan blade design, and it's similar to the ones we used on US Navy submarines. That should tell you they are quiet and move a lot of air. The housing on either end can be split from the center motorized fan module by removing a clamp. This allows for cleaning the fan or swapping out a bad motor. In theory, this feature simplifies a booster fan repair because once duct joints are assembled, especially in an HVAC system, they are difficult take them apart. I say "in theory" because you need to know how to use the clamps that hold the motor section to the inlet and outlet section. Loosen the screw until about 1/4 in of thread is showing below the nut. DO NOT unscrew the nut all the way. Leave the clamp assembled but loose. You sort of pop the clamp off, and when reassembling, you pop it back in place. It is similar to putting a bicycle tire on the rim. Note that the fan includes a second set of clamps, but these are used to attach existing ducting to the body of the fan.My application for this Inline Duct Fan was for HVAC ducts. Two legs of my system were fairly long and ducts were undersized. Installation was fairly simple. The set of steel duct clamps provided in the kit came in handy. I added mastic tape around the joint and activated the adhesive with hand pressure. Once attached, it's hard to take apart so I took my time to make a good seal and a mechanically strong joint. I needed to suspend my fan, so think about the mounting method before you get started. You could also use the metal bracket attached to the housing.I powered the fan with a relay circuit that energizes the booster fan only when the main HVAC unit comes on. I watched a YouTube video of someone else solving this requirement. I bought the relay on Amazon: RIBU1C Pilot Relay and use it to control both. At most, both fans draw 2 amps or less, well within the spec for this relay. After I finished the electrical work, I used the fan unit's 8 speed settings to adjust airflow and balance the HVAC system. I balanced the HVAC airflow by varying the speed on the fans. I have installed fans on two long duct runs. At fan speed 8 (max), the unit gets noticeably noisy, but it's also pushing a lot of air. You probably won't need top speed. In my system, setting the fan speeds at 3 to 5 balances the airflow. At this setting, the fan is very quiet and still pushes a lot of air. Airflow adjustments can be made with the speed controller. The rooms connected to the system are now much more comfortable. I'm ready for a hot summer!

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.

The sad part about fans is they make noise, and it's hard to get away from that. I did measure a higher flow of air than advertised - a plus in the right direction. Easy to install and the fact that the fan has variable speed is also a big plus. Seems very well made, which means it should last a long time, check back in 15 years and we'll see how it did. Removing the fan unit to get to the mounting holes was real simple and the instructions laid that out nicely. I have another fan by this manufacturer in my greenhouse, and it works awesome. Was a good purchase - yep - a good purchase.

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.

The media could not be loaded. Silent motor, high cfm, good suction and pressure. Fan comes with 2 duct clamps, zip ties, velcro wire ties, lag bolts, sheet rock mounts for motor and controller, and a couple other goodies.I have a lot of Hydrofarm inline fans, 4in and 8in that i use For my kitchen, bathroom and shop exhaust fans. They are very good and i have yet to have 1 die on me. The AC infinity won me over today. Its pressure and suction are just as good or better than a same size hydrofarm, what i love is NO MOTOR NOISE. I dont hear the motor at any speed, just the fan and the air being moved. I have the 10in fan and the 10in filter box installed under my bed as an air filter. On the lowest setting i cant hear the fan under the bed, i do hear the air intake but i can easily box that in and make it silent.
