QA-Deluxe 5500 CFM Energy Efficient Whole House Fan Includes 2-Speed Remote with Timer and Temp Control

Natural ventilation cooling system using modern technology and engineering. Installing a QA-Deluxe whole house fan 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. QA-Deluxe whole house fans use acoustical ducting for quieter operation. An R-5 insulated gravity damper isolates the living area from the attic when the system is not operating. Easy Installation. Unlike older style whole house fans, QA-Deluxe Fans are designed and engineered to fit between 16 in. and 24 in. on-center joists, no additional framing is required.
