It has a well-constructed design with multiple control options afforded by the smart controller.

Cons

  • 🔊 Becomes noisy at speeds 3 to 10, vibrations may be an issue
  • 🔧 Controller setup and settings are complicated and not intuitive
  • 🧩 Installation in bathrooms or specific setups may need creative solutions for controller mounting and cord management

  • Effective and Well Priced
Size: 4-Inch PRO, Smart Controller
I purchased this fan to exhaust warm air from a home theater equipment rack. With all the equipment turned on, the temperature in the rack quickly climbs to over 90 degrees. The equipment rack is recessed into a closet under a set of stairs, so goal was to activate the fan to pull warm air out as soon as the temperature rose to 80 degrees at the top of the rack. With the controller, it can be set to automatically and progressively increase fan speed after the temperature hits the target. Every 2 degrees after the target the fan can increase speed by 1 step. PROs: > Very quiet at fan speed 1 and 2. At 10, this fan pushes a lot of air. > Controller allows multiple control options - I just needed the high temperature option > Easy to install with the mounting plate - I got this mounted and installed in under 30 minutes. > Fan direction can easily be changed. The fan module just pulls out and you can change airflow without uninstalling - this is great to test whether pushing cold air in vs. pulling warm air out works better for your application. > Nice long temp/humidity probe and cable let me place the sensor exactly where I needed it. > Ability to place the controller wherever you want it as well. > Works seamlessly with their matching 4-inch flexible ducting, and wall mount duct grille. > Comes with two duct clamps > High quality construction -- strong mounting bracket, and thick plastic casing. CONS: > At speeds between 3 to 10 you definitely know it is running, though it is probably quieter than other fans. > I have this mounted to a wood support. At high fan speeds the motor vibration does reverberate through the wood supports - so need to play with how to isolate the fan if noise is important. > Controller settings are very complex given what you would typically want to do. To set the fan to turn on at 80 degrees and increment speed in steps as temps rise took a bunch of menu hopping and instruction manual reading -- not intuitive. In contrast this was a very simple setup on their AIRCOM fans. > Don't like the fact that in AUTO mode, multiple sensors can affect whether the fan turns on... Took a couple days to dial it in. High temp, low temp, high humidity, low humidity... hard to predict when the fan will turn on... I get this is geared for agricultural use, but setup is more complex than it needed to be. ... show more

  • Incredibly Quiet Exhaust Fan
Size: 4-Inch PRO, Smart Controller
Decided to replace an older bathroom fan in our downstairs bathroom. The heater had failed and it honestly sounded like a freight train when you turned it on. My son wouldn't use it because of how loud it was and how little air it moved. Shopped around at the local home improvement stores and tested all of the standard models and none of them were really any better. If they were quiet they didn't move air, if they moved air they weren't quiet. Ran into a post about the AC Infinity line. Although they were designed as grow house fans the ratings were outstanding and they met my two requirements. Move a lot of air and do it as quietly as possible. Ordered the T4 and it came packaged amazingly well with great directions for the use of the remote control. Hooked it up on the kitchen counter and man, it was quiet! Also moved air like crazy. Sure there is always going to be some noise and vibration when you have it on full speed, but when you run it at half speed you can barely hear it and it will clear out a standard 8x10 or smaller bathroom of moisture in just minutes. A few notes on installation for a bathroom. 1. These were designed to be used in a grow room installation. The mounting options for the controller box are limited. You can't flush mount it and I wasn't able to find a mounting bracket that would allow it to be installed in a wall. Had to mount it on the wall. Looks ok but the cables can't really be hidden. 2. The power is plug in only, so if you want to hide the cord you'll have to install an outlet or have access to an existing outlet. I suppose you could cut off the plug and hardwire it, but the manufacturer suggests not to. This is an amazing fan and I'll be adding them to the other bathrooms in my house as well. Hoping AC Infinity comes up with a flush wall mount or a different controller design. Also a hardwire option would be fantastic. For a product this good they are so close to perfection. ... show more

  • Controller is nice bonus
Size: 4-Inch PRO, Smart Controller
Controller works well with intake fan to help control my climate. Paired with ac infinity humidifier, the climate is automatically controlled based on my set VPD targets. Fan moves decent amount of air and works well for 4x2.
