Product Description

Product Description
A high-airflow ventilator fan designed to control the temperature and humidity levels of your crawlspace, basement, attic, and garage. This system reduces humidity levels while expelling odors and stale air from your home. Features a WiFi-enabled LCD with smart thermostat and dehumidistat control, as well as triggers, fan speed control, status alerts, and more. Included 12 ft. corded sensor probe plugs into the controller to provide temperature and humidity readings. The heavy-duty build includes a stainless-steel mounting frame and IP-55-rated fans. Features dual 120mm PWM-controlled DC fans that are highly efficient in maximizing airflow at lower noise and power levels.
Smart Programming
The onboard controller features smart programming to keep temperature, humidity, and VPD in check to produce the optimal environment. Set dynamic programs that go beyond on/off triggering and adjust fan speed in response to changing indoor climate. Minimum baseline levels keep the crawlspace fan running at low speeds for consistent airflow, while timer, cycle, and schedule modes add custom on-demand activation. Securely connect to the AC Infinity app via WiFi to utilize automation capabilities from anywhere throughout the day. Remotely access your devices, unlock advance programs, set alarms and notifications, view historical charts, and export CSV data.
Heavy-Duty Performance
This crawlspace fan system is enclosed in heavy-duty stainless steel with spiral fan guards. Utilizing DC motors that are controlled using PWM (Pulse Width Modulation), the fans can maximize airflow while reducing noise and power consumption. In addition, the dual 120mm fans are IP-55 rated to be highly resistant to liquids and dust particles. The motor houses dual-ball bearings that are rated at 67,000 hours and allow this fan system to be mounted horizontally or vertically.

- Reviewed in Canada on June 1, 2020Verified PurchaseIt doesn't move a ton of air (its using 2 PC fans that are kind of small) but its DC powered (super cheap to run 24/7) and does vent air. I'm happy with the purchase.
- Reviewed in Canada on September 8, 2020Verified PurchaseGreat for venting rooms through small opening, temperature setting to turn on/off is great! Could be used for audio system cabinet to control its internal temperature. Very quite as well.
- Reviewed in Canada on January 25, 2020Verified Purchasewould have been nice if it came with a vent as I used mine in my garage wall to get rid of moisture.

5.0 out of 5 stars Funktioniert
Verified PurchaseIch bin voll und ganz zufrieden!!(2.ten schon bestellt) Habe den Lüfter aber zweckentfremdet zum belüften eines Gewächshauses.
Zum Gerät selber man hat sehr viele Einstellmöglichkeiten die Lüfter kann man in 10 Stufen einstellen wobei er in den Stufen 1-5 sehr leise läuft.
Zu den Einstellungen Anleitung in Englisch wobei, wenn man sich etwas Zeit nimmt bekommt man es auch mit rumprobieren hin. Das Verbinden mit der App (Android) ->Account anlegen lief super einfach, WiFi/Bluetooth(zu beachten WiFi nur 2,4-GHz Band ). Über die App kann man sich einen Verlauf anzeigen lassen und selbstverständlich das Gerät auch einstellen.
Würde es wieder bestellen

5.0 out of 5 stars Used this as an exhaust fan in the bathroom
Verified PurchaseMy place was built in the 70's and the contractor did everything they could to save a dollar. Including not install a bathroom fan. Thankfully there is a window in the bathroom, so I was able to place this fan in the window. The humidity control function is nice, I can keep it idling at 20% output, then when the humidity goes up, ramp the fan speed up to 100%. The controller is easy to program without the app, and there is a bluetooth app if you are so inclined.

5.0 out of 5 stars Connecting TitanSeries T8 to Bluetooth/WiFi
Verified PurchaseInstalled the T8 as a garage exhaust vent. Unit works great and is very quiet during high speed. My only issue was syncing to Bluetooth. Instructions on AirTitan Series booklet page 55 is incorrect. It states to select "Controller 69 Pro". Instead when adding a device select "Smart HVAC" followed by "AirTitan Series" and proceed with screen instructions with syncing to Bluetooth. (Ensure that Bluetooth is enabled on your mobile phone and that AC Infinity app entry has Bluetooth enabled as you scroll throught he apps).
Once done, create a User Account if you want to install using WiFi where it will ask for your WiFi Name and Password. Follow the instructions on the screen.
Hope this is helpful cause I spend alot of time trying to figure this out until I contacted the customer service who was most helpful.

5.0 out of 5 stars One of the most feature rich units you can get at this price-point with great build quality!
Verified PurchaseSo, I was looking for a automatic fan to help remove hot air from my garage. It can get up to 120F in there during our desert Arizona summers! I've tried several models. The majority of which operate on a simple dial system for either humidity or temp.
Compared to those, this device is absolutely loaded. It allows you to set a maximum fanspeed, trigger the fans to automatically run based on a trigger point you choose which are:
High Temp
Low Temp
High Humidity
Low Humidity
It can also be set it to just be ON or OFF as well.
You can also set it to start making an alarm beep if the temperature / humidity % goes above or below what you specify.
The fans also slowly ramp up to the maximum speed you allow, providing for efficient operation.
The device arrived nicely packaged, feels very well made, and comes with everything needed to mount. You get wall screws w/ anchors as well as threaded bolts.
It even features an external temp probe that can go a fairly long distance away from the device, allowing for an accurate reading in the area you care about most.
They make a version that allows for air to be vented outside as well as a version that allows air to be vented inside. The fans are easy to flip around if you don't mind to taking the unit apart as well.
All in all, I highly recommend this device. It’s feature rich operation and fair price point make it a hard to beat unit. Especially since the price is comparable to what some of the larger “knob only” style units are.
