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 54 dBA on high, the 4.0 is very 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 which features an LED display and 5 Timer Functions 1, 2, 4, 8 hours or ON. On high speed the system operates at a powerful 3860 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 4.0 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 4.0 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.

I live in the Ceres, California where it reaches 100 degrees regularly. After using your WHF 4.0 in my home for (1) month. My energy usage went from 2409 kwh for this billing period in 2013. To 1450 kwh in 2014. That relates to nearly $140.00 saving where I live. I only ran my A/C once the entire month. There was a couple times in the month that my home became uncomfortable. But my iPhone said the temperature was coming down in an hour or two. So family suffered for a little here and there. But it’s funny to have to shut off the system at night because my family is freezing. Best purchase I have made in years for my home. Thanks for the great product.
Purchased this quiet whole house fan for a client, installed it last summer. All I can say is WOW… This fan is so quiet I had to get back up on the ladder and stick my head up there to make sure it was actually running. Compared to the old school belt driven fan that was ugly, noisy, dirtying and drafty, there is no comparison. The build quality of this unit was impressive, now I’m going to be getting one for my own home! Installation is very straightforward, took longer to muscle the old fan out of the attic then it did to install this. Even though I am a contractor, I would say a weekend warrior, or average DIY should have no trouble installing. Instructions are clear and easy to follow, and presale support was excellent, I had no need to contact them after the sale as it was so easy to install. I would imagine their support to be excellent given they have quick and friendly communication. If you are on the fence and shopping your local home improvement stores, do yourself a favor and stop looking. Yes, the unit is pricey compared to the junk local stores sell, but the quality, energy efficiency and lack of noise are WELL worth the cost!
I have had Whole House Fans in all my past homes but they were both noisy and energy gobblers. The Centic Air is the quietest and most energy efficient whole house fan that I have had. Love the 2-Speed remote and the R-50 damper since I live in Colorado. 5-Stars thumbs up!!
I had a Quiet Cool fan and I was not happy with it and change to a CentricAir. The CentricAir is quieter and more energy efficient. The German motor and composite balanced 5 blade system in the best.
