Exceptional Power, Extremely Energy Efficient!

The CentricAir 4.0 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% power while using 1/3 less energy as compared to other industry standard fans.

Extreme Engineering - Built To Last, Ultra Quiet

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.

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 CentricAir 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.

Maintenance-Free Operation

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

    Outstanding customer service, very informative, great product, exactly as described

  2. Arthur Sullivan (verified owner)

    Wonderful service!! We ordered the fan on Thursday and arrived Monday morning. Just in time for our heatwave. I spent the day installing it and that night we tried it out for the first time. My wife was a happy camper because she could actually sleep and not hear the noise of the box fan in the window. At first she was skeptical about this fan and would it would work in our large house. Especially since our bedroom is upstairs where all the heat goes. She can’t believe that in under 30 minutes we can have the entire upstairs cooled off and then the downstairs in only a short time after. We don’t know why more people don’t install a system like this one. It is ten times better then air conditioning. With air conditioning you just get stale air blowing around not very good for your health. But with the Centric whole house fan it is fresh air from outside. We cannot wait to try it in the winter when the house needs a good airing out. Another positive about this product is that our energy bill will reasonable compared to if we had air conditioning. So as I said, this is an excellent product, great customer service and a must for every home that wants to stay cool in the summer and have healthy air to breathe.
