Exceptional Power, Extremely Energy Efficient!

The CentricAir 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.

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 CentricAir 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.
