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 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.

Two Speed Wireless Remote Control with Timer

The optional 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 3011 CFM. Set to low speed the system provides a comfortable flow of air while maintaining a whisper quiet noise level.

Heavy-duty 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.

  1. Worth every penny! 5 Star Review

    Posted by on 14th Sep 2016

    I’m very familiar how practical a whole house fan can be, to move air for cooling, or to just clear the house of odors or accidental cooking smoke, at your command. I didn't want to buy, and install another noisy, big bladed, high velocity fan, that opens noisy vibrating louvers with air volume. Searching the web, I learned about many products. Thankfully I stubbled across the comparison video of Quiet Cool vs Centric Air. I called the company and Dave explained any questions I had. It all made perfect sense. It was quiet, the grill is attractive, the quality is second to none, the multi function wireless remote eliminates having to run electrical conduit for a wall switch, the winter R50 damper was an easy decision as I live in Chicago, the installation was truly easy, along with personable customer service. The price seemed rather expensive, but of no consequence, when looking for the best! I got what I paid for, and I LOVE it! You won’t be disappointed. The 3.1 really moves the volume of air I was looking for. My home is 2500 sq. ft. with 9 ft ceilings and an 18 ft living room ceiling. I’m so glad I purchased the indoor-outdoor thermometer also, as it leaves nothing to your imagination, when it comes wondering if you should turn the fan or not. The last thing I do is to check my phone app for weather humidity. If that’s low enough, I’m good to go. Thank you Mike and David at Factory Fans Direct.

  2. Great Engineering 5 Star Review

    Posted by on 6th Jun 2015

    I have a 3700 sq ft home with a great room with 20 ceilings and live in the Chicago area. I wanted a fan that could be put into a vertical wall and also have a thermal barrier. The CentricAir 3.1 with the Power Damper worked perfect. I mounted the damper at the high point of the vertical wall and added R-30 into the damper door and I was very pleased. Great engineering.

  3. Great Fan 5 Star Review

    Posted by on 6th Jun 2015

    I have a 3500 Sq. Ft, single level home and shop around and compared all the house fans out there. It was between Quiet Cool and CentricAir, after hearing both fans I chose CentricAir. It was quieter and I liked the German computer-balanced 5 blade fan. I have in my house now for over 2 months and love it. It is whisper quiet, cooled my home and brought down my electric bill. Great Fan!!
