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 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 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.

    Replaced old fan with Centric Air 3.4

    Posted by Barry P on 10th May 2022

    We finally replaced our old noisy all house fan with a Centric Air 3.4 fan. We went with the Centric Air fan as the housing and blades are molded plastic so they do get bent like the other brands plus they have a better German motor and it is really quiet. The big selling point is the remote control they sell with their fans, wow! it makes all the difference. You can set what temperature you want the house to be and it will automatically shut off the fan once it gets to that temperature. Excellent product and service.

    I reviewed all the whole house fans on the market: Quiet Cool, Air Scape, Tamarack, etc.. and nothing compares to the Centric Air with its German motor and 5 blade computer balanced system. It is quiet, energy efficient and the highest of quality. I was really impressed by Mike Miller knowledge at Factory Fans Direct. He is a whole house fan expert.

    Vertical Installation

    Posted by Joe on 17th Aug 2020

    Package installed easily, however, with vertical installation I found it was best to frame around duct for slickest install. System is very quiet and we look forward to utilizing it daily when cooler mornings return in September
