AC Infinity AIRTITAN T7 Ventilator Fan with Temperature Humidity Controller

Originally I purchased a different brand exhaust fan for more money and was disappointed that the fan speed was only on/off, not variable. Did a bit more research and bought this unit instead, and I am actually amazed by how full featured it is, for less money. Key features: the probe detects temperature and relative humidity, and will RAMP UP the fan speed when it gets to your chosen temp/humidity level. You can also adjust the rate of ramping (ie: 1 speed setting per every 1deg, 2deg, 3deg, etc over your target). You can create schedules and even orchestrate multiple units to be controlled from the same control unit. There is an app! I expected it to be disappointing because of a reviewer in the app store who claimed they couldn't monitor data or get alerts when away from their home network. This proved to be FALSE. I was paddling on the lake today and checked in on my greenhouse temperature and humidity levels, from my paddle board. The fans are super quiet and you can set a minimum "always on" speed. If there's a feature you can imagine, this setup will accommodate you. I am rarely this impressed with a purchase, but this one absolutely exceeds my expectations, again and again. Got one regulating the temps/humidity in my greenhouse and, based on this experience, I just bought a second unit to manage humidity in our walk-in-closet. Above and beyond, AC Infinity. Thanks for the quality product.

This product is about as well engineered, as well documented, as well packaged, and as well supported as it could possibly be. First, the engineering: The stainless steel face plate is precisely cut and plenty strong. Easy to locate and drill four corner points for a simple install over the foundation opening. It will remain rust-free. The twin fans are removable and reversible if you'd prefer to pull air into your crawl space. They come preset to exhaust air out of the crawl space. When the fans are on, you cannot hear them unless you are 3-4 feet away. No vibration, no wind noise. I have had it running nearly non-stop for about a month now with no sign of overheating or any change in noise level. The unit and controls just feel solid. I bought it to replace the loud, single motor exhaust fan I had under the house that I got from a home improvement store. That one always ran hot and probably used lots of power while only exhausting 160 CFM. If I read correctly, this unit only uses a few watts but draws 240 CFM. It should save electricity. The documentation: This is not one of those skimpy, poorly translated instruction sheets. The documentation booklet is complete, well written, and extremely easy to follow. It addresses every feature in clear English with plenty of illustrations. You will have no issues understanding every function if you just read the instructions first. Which leads to packaging: It is a crawl space fan, but it has a velvet lined box. The packaging says the manufacturer really cares about quality and put lots of thought into the product from beginning to end. It was packaged like high-end electronics, which it is, but it was still under $100. Everything you need to install and operate the product is included, including power supply, programming control box, and wired sensor cable, all connected with cables supplied. Finally support: I got the unit with the thermostat and humidistat built in. You will need a 120V outlet under your crawl space to plug it in. I did not need any help to figure it out in just a few minutes, thanks to the documentation and what turned out to be an amazing, free AC Infinity app you download from the App Store. The control box with digital readout stays under the house, so I rely on the app to tell me the temp (F or C) and humidity (%) under the house at any time, anywhere (also kPa, but I don't need that), and it even graphs trends or sounds alarms/sends alerts if you want. You can control and change all settings via the app, too. I had a remote digital temp and humidity sensor under the house already, and the readouts are within 2% of each other. Temp is right on. I have the product set to come on if temp OR humidity rises above a certain point. The thermostat and humidistat work concurrently, as they say. Either one (or kPa) can turn the fans on (or off) independently depending on how you set it. You can set upper and lower fan speed from 0 to 10 so that "off" is either truly OFF (0 RPM) or just a lower RPM, and "on" is max RPM or something less, all on a scale of 0 to 10. You can set a range for all control parameters so that "on" and "off" are separated by whatever degree or % you choose in auto mode. It can also be set to work on a timer, to cycle on/off as you choose, or work on a certain daily schedule. Hard to imagine more programability, but it is very intuitive. If you can set an alarm clock, you can set this thing. Highly recommended!

This is a nice little unit. It didn't move as much air as I was hoping, but I have a large basement. Also the controller only works one function at a time. You can only choose to have it turn on and off by only one of the setting of your choice: temperature, humidity, etc. If you want it to run on a different setting you need to manually select it until you want something else. The display is nice and easy to read. I also like that the display will shut off to save energy and be less eye catching.

I have two T7s for venting out our two basements--one for each. They have been working without a hitch for nearly two years. While these units cannot take the place of a radon mitigation system, they do help lower the radon levels and suck the stale air out. But I have the fans on low settings only, lest they generate too much negative pressure. It could cause backdraft for your gas water heater, among other things. So be careful here, since you would be interfering with the balance of air pressure between the inside and the outside. Get professional help if you are unsure of what you are doing.

What an amazing product! I have a storage closet outside that has had a lot of issues staying cool, and getting extremely humid. It gets that damp mildew smell. This is such a clean installed item with countless applications. It would be perfect for an AV closet, computer closet, garage, or shed. The thermostat does both humidity and temperature. Easy install , extremely clean looking. Very quiet and well built. Just make sure there is a a good air return for maximum effectiveness. The best part is that musty smell is gone! Now i feel so much better having my stuff stored! It is more expensive that other options and may not pull as much air as more industrial vents but it's perfect for smaller environment. It would not be suitable for a large garage, or large attic space. The AC Infinity AIRLIFT T10, AC Infinity AIRLIFT T12, AC Infinity AIRLIFT T14 . Thats 10 inch, 12 inch, 14 inch. The best part about these fans in you can attached a second set of fans to the unit. So if it comes with one fan, you can add a second fan. Which is amazing. So lots of possibilities! It is a no brainer! Enjoy!

Setup is running well. But no secured network connection possible!!! No WPA2/3 but a price of a “Mercedes”. Unbelievable und frustrating!!! I will upgrade my rating if the next firmware update will deploy at least WPA2 (state of the art or even already aged)

Used as a crawlspace exhaust fan, works great pulls the crawlspace into a slight negative pressure and now draws houes hold air into crawlspace preventing any stale odors and controlling humidity. Just wish the wires for the remote were longer or an extention was avalable.

This unit is whisper quiet, easy to install and the control panel is easy to use. Only complaint and it’s a minor one. With the unit was not hard wired with such a big adaptive port to the controller. That’s it. Other than that worth every penny.

like can be set for temp or humidity

Product seems fine. I do find the display a bit dim when you are in bright light.
