AC Infinity AIRTITAN T8-N Ventilator Fan, Intake

It is in my unfinished lower level to reduce radon and it works. It is good looking and quiet and programmable for temperature, humidity, and timers. I have it on a schedule to reduce radon and it also lowers the humidity. It needs an intake air source for flow through ventilation. Go to their website for intake fans and flex tubing. Or get a second one for direct intake located at the other end of the space. The instruction book explains the settings. The fans can be reversed for in or out flow. Customer service is excellent. My fan as delivered from Amazon was the old model, which did not match the description. AC Infinity sent the new correct model direct from the factory with a prepaid shipping label to return the former model.

I've had odor problems in my 50 year old crawlspace since I bought the house. Circulating the air with a regular fan didn't really help. I have purchased 4 of these fans, 2 to pull air into the crawlspace and 2 to push old stagnant air out of the crawlspace. Unbelievable difference in the air quality in my crawlspace by doing this. The most amazing aspect of these fans is that you can install them with the controls facing the space or facing out of space where you can see the controls. You can unscrew the face plate, flip the fan blades if you need to change the direction of the fans. And they are pretty weather proof, but not freeze proof, so just remove the fan in the winter. Installation is very easy, they fight perfectly between 16" on center wall studs. It took about 10 minutes per fan to install them. What an amazing manufacturer this is; product works very well, and is easy to install, not to mention how nice they look on the siding. Thanks so much for a great product!!

Great build quality. Easy set up with supplied directions. This intake fan does not like to the app like the exhaust fan. All programming is on the actual unit. So, that is a slight inconvenience. You have to go to the fan and change the settings. Mine is outside on my swimming pool - pump house. I am using it with wall exhaust fan for excess heat removal from my gas pool heater. The 2 units are working perfectly to keep the heat down and protect the equipment. It is also providing a good supply of combustible air.

Construction - well built. moves decent amount of air . digital speed adjustment, temperature on/off works well. really wish there was a reverse option so I could use this in a return air vent.

This has been a game-changer for us-- we live in an apartment with open vents in the wall above the bedroom doors for circulation-- but the room is at the end of the AC run, and the single register just can't do enough to properly heat or cool the room. We can't keep the bedroom door open at night because of a toddler and cats or this probably wouldn't be a problem. Additionally (and more importantly) we bought a CO2 meter to see how bad our uncirculated air was getting overnight, and we were shocked to find that our levels were as high as 1600ppm overnight-- way higher than is healthy. I installed this fan in the footprint of the door vent to pull fresh hallway air into the room, and it has reduced our levels to 1100-1200---still not great but WAY better than before-- and it's also helped with the temperature control as well-- I love that it's adjustable-- at 7/10 it's a mild background whir that's nearly inaudible above the existing air filter we have in the room-- neither my wife or I find it bothersome. I also love that the display LED can be turned off-- really grateful for this fan!!!

Even with a clear path for the air to move into room 1 and out of it into another space, air isn't moving. The only thing that would make sense is if the cfm label is just a full lie. From how it sounds at max, you'd think it would be moving a lot of air but from my experience it definitely isnt moving much.

I somehow managed to order the intake model of this fan instead of the exhaust model but it was easy to reverse the flow following the instructions in the manual for the single fan T3/T7 models. Simply remove 4 screws in the four corners of each fan on the backside to remove the mounting plate and 4 more from the corners of each fan on the front face to free the fans and flip them over. In doing so I noticed a small battery like a CR2032 on the circuit board which allows the fan to keep the settings when it is not connected to power. So it can be programmed before you get in a crawl space to install it. It came with 4 machine screws and 4 wood screws with screw anchors but if mounting in a standard cement block opening you need a masonry bit and probably concrete screws. The really nice feature is the phone app that controls via bluetooth or wifi which is easier to program the fan than pushing buttons on the fan and allows additional programming features like timers. It also provides a graph of the humidity and temperature readings so you can see how it is working. However the instructions for connecting the app to the device were out of date. It was necessary to choose add device then select SMART HVAC and then select AIRTITAN. Customer service was good at answering questions before I ordered and after the purchase.

I love this fan assembly!! It give me full access to completely control the climate in my humidity/germination chamber via via Bluetooth as well .... definitely worth every dollar.

I had a bad crawl space smell coming through the ducts. The house is almost 40 years old and I had left things in the crawl space like books and old clothes for years that I'm sure didn't help. We live in British Columbia where it's rainy all winter, probably made it worse. Anyway, I purchased two Airtran fans, one as an intake and the other outflow. The installation was fairly simple but I admit I got my young son down there to do it because I never would have been able to do it right. He placed them where the original screens the builder had installed on each side of the house for crawl space airflow. For the most part they fit nicely, I think the problem my son encountered had more to do with where the builder placed the screens and a 2x4 that was in the way so he had to do a minor modification that I think most men who are handy wouldn't see as a big issue. We completely cleaned out and shop vac'd the crawl space and then sprayed it with Odoban first using one of those outdoor sprayers you use for spraying trees. We left some extra house fans down there for about a week get the air really flowing. The smell is completely gone, I'm so happy because I'd had two separate companies come visit and quoted me $3k-$15k to remediate the crawlspace. This cost me around $400 including the Odoban that I got at the hardware store. The floor of the crawl space is concrete not dirt. Hope this helps someone, I saved a lot of money with this solution.

Quiet and efficient

il devrait nous informé mieux un model qui pousse air et autre rentre air ... ok on peux ouvrir et tourné la fan ... le T8 entre air ... la programmation pas très bien explique ....fait la job.
