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.

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

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.

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 purchased this unit for a client, installed it last week. 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 had old styles home house fans in the past and they were loud, dirty and energy gobblers. The Centic Air is the quietest and best engineered fan that I have owned. Five STARS*****
We can't thank you enough for our incredible new Centric Air Whole House Fan. It's amazing how quiet, yet effective it is. Friends of ours have a whole house fan that sounds like a Train running by the house. We can hardly hear our unit running. But the best part is it's unbelievable how cool our house is. Last night my kids actually used their blankets to cover up all night. Not something we normally see. I typically have 2 fans and a window A/C unit on in our master bedroom just so I can sleep. Not anymore. Now I just open the windows, let the Centric Air unit do its job and the natural air from outside cools the house down just as though we had A/C going all night. I can't wait to tell our friends about your product ...it's just what my family has been looking for to ease those hot, sticky days & nights.
Our Centric Air fan does a really good job of cooling off our house. Where we live it usually cools off in the evening which is when the fan excels. It pulls in the cool evening air and pushes out the hot air. The installation was quick and the crew left everything spotless when they were done. It also does a good job of clearing the air if dinner gets burned!
Had the 4.0 installed last week. What amazing product. So happy we have made the decision to purchase and install in our home. The ease of cooling the second floor from no fan to the whole house fan is night and day! Great start to a cooler night. Thank you!!
If you have a larger house like us, this whole house fan is definitely for you. The fan actually provide greater efficiency than other whole house fans, allowing us to cool down different areas of the house at once. I also like the variable power settings on the remote, which really makes it easy to combat both sweltering days and mildly unpleasant days. 5-Stars
We had a Centric Air 4.0 installed last year. We have used it every month. In the winter on warm days to draw in warmer outside air and every night during the summer. The fan really work and you can barely hear it. We run them all night long. Not only are we really satisfied, we were really impressed with the installer. At his suggestion we added extra vents. With the fan running the attic cools down in the evening keeping the house cool during the day. One more thing. Our electric bills this summer are way down. I did a lot of comparison shopping on the internet and talked to friends with fans. This one is by far the best, even though a little more expensive. Great product!!
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.
