Features  & Benefits
Exceptional Power, Extremely Energy Efficient!

The Centric Air 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% 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 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 2-Speed remote control with timer is the 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 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 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.

Maintenance-Free Operation

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

    All I can Say is WOW | Referred Friends $50

    Posted by Brad K on 11th Aug 2019

    We have a 3,800 sq ft home with an old style 30 inch ceiling mount fan and it was time for a change. We looked at the Quiet Cool and Air Scape and was impressed by the quality, engineering and quietness of the Centric Air. The new 2-Speed Remote with Temp setting was much better than the old wall switches. We made the right choice. I told a few friends and got $50. WOW
