Comfort Cool Fans 3300W Whole House Fan 2425 CFM (HVI-916 Certified Airflow Rating) 2-Speed Wall Switch with Timer/Temp Control R5 Damper

Natural ventilation cooling system using modern technology and engineering. Installing a modern whole house fan by QuietAir Fans can significantly reduce your air conditioning bills. If you live in an area with hot-days and cool nights, stop throwing money away on air conditioning and save by drawing the cool night air into your home. This is not the old belt drive, loud, noisy and vibrating whole house fan of the past. QuietAir Fans use acoustical ducting for quieter operation. An R-5 foam insulated gravity damper isolates the living area from the attic when the system is not operating. Easy Installation. Unlike older style whole house fans, QuietAir Fans are designed and engineered to fit between 16 in. and 24 in. on-center joists, no additional framing is required.
