The CentricAir 3.4 whole house fan delivers a powerful 3242 CFM (HVI-916 certified airflow rating) and requires about 4.0 sqft of net free attic ventilation. It uses 382 WATTS of power and costs about $0.08 per hour to run. It’s designed for two story homes up to 3400 sqft and single story homes up to 2500 sqft.
It comes with an option of an On/Off remote control with timer or two-speed (Hi/Low) remote with timer & temp control or two speed HI/LOW wall switch and digital timer. Also available with select CentricAir products is our exclusive cold climate damper. (See Included & Upgrade Options Below)
IMPORTANT: All CFM ratings for CentricAir have been verified by an independent testing agency authorized by the State of California as meeting the strict (HVI-916) standard. When comparing CFM (airflow) ratings against similar style whole house fans, it is important to compare the HVI-916 CFM certified airflow rating. This is the true apple to apples comparison.

The CentricAir 3.4 is a high quality, very powerful and ultra quiet alternative cooling solution. It uses a German engineered industrial grade fan motor that can provide 30% more power while using 1/3 less energy as compared to other industry standard fans.
These high-end industrial grade motors are built to last and are rated for approximately 40,000 hours of operation. The noise level is also really something to hear – or, actually not hear. At a very quiet 52 dBA on high, the 3.4 is whisper quiet. Every aspect of this system is built to a rigorous specification suitable to demanding industrial applications and is completely maintenance free.
A fundamental problem with traditional whole house fans was air leakage between the attic and living spaces. This could result in dirty attic air entering your home. The 3.4 takes care of this problem with an industrial-quality damper that is thermally insulated and maintenance free. Silicone seals are provided to ensure sealing longevity; they also provide phenomenal resistance to weathering and changes in temperature. Silicone seals have an approximate service life of 30 years and remain flexible down to -40 degrees F/C.
The CentricAir 3.4 comes with a high air flow register that reduces air movement noise through the register. These high-performance grills look great too, so your system looks as inconspicuous as it sounds.
The German-engineered sealed motor and damper never requires lubrication or maintenance of any type.

Just installed yesterday, and the install is fairly easy. The fan is super quiet and works amazing, The quality of the fan seems to be very good as well. Mike with Factory Fans Direct was very helpful and informative, and recieved with in two days. Also get the two speed remote, works great too. Thanks again Mike.

First of all, we love our whole house fan. It’s an amazing addition to our overall cooling system (we already have central air) but got this to air out the upstairs, stuffy bedrooms and save our poor a/c from being overworked. There are a couple options for purchasing and installing your house fan and my husband did a loooooot of research before making our final decision, and we are so glad we (he) chose a CentricAir.

Just finished my first year with the 3.4. I used it heavily last summer. Then, it sat idle all winter and spring except that one day we accidentally burned salmon on the stove, it cleared the smell quickly. Hot weather is here now and we are using it again. It’s working fine. I installed it myself the day it arrived from centric air (I set up everything in my ceiling at a selected location the day I got the shipping notification). I have the wireless remote Velcroed to the wall next to the thermostat. I watch the outside temperature and as soon as I see it drop to my house temperature I turn off the ac, open the windows and turn on the fan. It’s great! My house used to cook all night, heat soaked from the days’heat and I would end up using the ac even though it was cool outside. Now the house is chilly in the morning with the windows open. Love it!

I installed the 2.7 in our previous house and now ready for a 3.4 in our new larger house. The 2.7 was amazing and expect the same from the 3.4. The upgrade 2 speed remote is a no brainer….plug and play.

I just wanted to say, I’m quite pleased with the fan, and I’m glad I didn’t buy the smaller capacity unit. It takes my house from uncomfortably warm to as cool as I need in an hour’s time and has so far completely eliminated the need to run the portable a/c unit. It’s also as quiet as I could’ve hoped for – the sound isn’t a factor at all (I have to be standing directly underneath the grille to even know it’s opened or closed). We haven’t yet encountered the warmest days which come in late AUG & SEP, but I’m confident that running the fan late in the day after the sun is almost down will have the house cooled off in short order. I would buy it again and only wish I’d put it in years ago. If the state wants to cut everyone’s energy use, they should be subsidizing these things! (I just have to say, after explaining where the air is coming from and going to repeatedly to my wife, I suspect many people somehow simply don’t understand how these fans accomplish their cooling…)
