The CentricAir 3.4 whole house fan delivers a powerful 3242 CFM (HVI-916) and requires about 4.0 sq. ft. of net free attic ventilation. It uses 382 WATTS of power and costs about $0.05 per hour to operate. It’s designed for two story homes up to 3400 sq. ft. and single story homes up to 2500 sq. ft.
CentricAir whole house fans use a German engineered fan that is 30% more powerful and uses 1/3 less energy than other industry fans. These energy efficient fans are rated for 40,000 hours of operation and come with a 15-year warranty.
Provided with the system is a gravity backdraft damper, acoustical ductwork, custom high airflow register, on/off remote control or wall switch & timer and all necessary hardware. Also available with select CentricAir whole house fans are our exclusive two-speed remote control with timer and cold climate damper. (See included and upgrade options below)
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.
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.
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.
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.
The German-engineered sealed motor and damper never requires lubrication or maintenance of any type.
