Features & Benefits
Exceptional Power, Extremely Energy Efficient!

The Centric Air 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.

Extreme Engineering - Built To Last, Extremely Low Noise

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 49 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.

Two Speed Wireless Remote Control with Timer

The two speed remote control with timer is our most versatile control and features an LED display and 5 Timer Functions 1, 2, 4, 8 hours or ON. On high speed the system operates at a powerful 3242 CFM. Set to low speed the system provides a comfortable flow of air while maintaining a whisper quiet noise level.

Heavy-duty R-5 Energy Star 1" Poly Foam Maintenance Free Damper

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.

Low Profile - High Air Flow Register

The Centric Air 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.

Maintenance-Free Operation

The German-engineered sealed motor and damper never requires lubrication or maintenance of any type.

    Best Fan | Great Customer Service

    Posted by Craig M on 5th Mar 2023

    Just wanted to thank you for your great product and service!! I reside in Utah and love the R50 cold weather damper with the 3.4 fan. The hot desert temperatures we experience have been much more bearable with this excellent fan system. It is working perfectly, is very quiet, and really draws the air through my home. Your expertise and friendly service were awesome!! Your DIY instructional video was very helpful. The installation was straight forward and went very well.

    Centric Air 3.4

    Posted by Kevin Schumann on 23rd Sep 2022

    I installed this myself with little trouble. It does exactly what I wanted it to do with little noise. The A/C does not run as much after cooling the house down in the mornings and evenings. The best part was the customer support from Mike. It is rare to get quality and friendly support now a days but he helped me with all of my questions and concerns.

    Great Fan and Service | $50 Bonus

    Posted by Ed H on 10th May 2022

    We chose Factory Fans Direct as our company to purchase our new whole house fan and we are very satisfied with the product and service. The Centric Air is far better than their nearest competitor and come with a 15 year warranty. The fan is very quiet and pull a lot of air through the house. We feel that the price for what you get was very fair. If you are looking for a whole house fan company give them a call and you will not regret it. Also they offer a $50 referral bonus. Great people.

    Had Whole House Fans for over 20 Years | Chose Centric Air

    Posted by Steve R on 14th Feb 2022

    We have had whole house fans in two homes we owned, a time span of 22 years. When it was time to replace our old fan, I decided on Factory Fans Direct and Centric Air. I can 100% recommend them, from the concept, to the product, through the sale by Mike. The sound of air coming out of the ducts due to using the air conditioner is louder than the noise from the Centric Air fan on low or high. At approximately $.05 per hour, there is no doubt as to how I will be cooling my home overnight this summer.

    WOW - What a difference!

    Posted by Jeff Freeman on 20th Jul 2020

    Wow! What a difference our Centric Air Whole House system has made. I am glad I waited until I found the Centric Air system. VERY quiet. Unbelievably quiet. My wifes number one concern was the noise of the fan. No issue with the Centric Air 3.4 system. The upstairs temperature has dropped 15-20 degrees and is within a couple of degrees of the first floor. Running our air conditioning MUCH less and not at all at night once the outside temp drops and we open doors and windows.

    Easy to install too. You can do this! I did. Thank you Factory Fans Direct!

    New install with R50 damper

    Posted by Joe R on 19th Jun 2020

    I have always wanted a WHF and the R50 damper sealed the deal. This fan is very quiet compared to any window unit. Powerful and as an added bonus it cools off the attic! Last summer I cooled off the house with a very noisy window fan but the 2nd floor would quickly heat back up as all the hot air in the attic was still there. The Centric fan forces the hot air out! Mike was awesome to deal with, answered all my questions and ensured a quick and easy installation.

    Best Engineered Whole House Fan

    Posted by Tom L on 16th Feb 2020

    I am an engineer and reviewed many whole house fans on the market to determine the best for our home. Quiet Cool, Airscape, Tamarack and others. The Centric Air stood out with the German motor and 5 blade computer balanced system. Optional R-50 power damper very well designed and new two speed remote controller. I am very pleased.
