From the Manufacturer
The Panasonic FV-11VQL5 WhisperLite 110 CFM fan features a totally enclosed condenser motor and a double-tapered, dolphin shaped bladed blower wheel to quietly move air. Panasonic fans are quiet enough that you might not even know they're on. With a 1.0 sone level and rated 110 cubic feet per minute, this fan is designed to give you continuous, trouble-free operation for many years due to its high-quality components and permanently lubricated motors which wear at a slower pace. We designed the electrical configuration of this model's condenser motor to allow it to operate at lower temperatures, increasing the life of the motor and bearings. And, the fan housing is made of heavy-gauge zinc galvanized steel and painted to protect it from rust. This Energy Star qualified fan has a built-in damper to prevent back draft, which helps to prevent outside air from coming through the fan. This unit not only ventilates the air in your room, but provides overhead lighting as well. Two 18-watt compact fluorescent lamps and a 4-watt nightlight are included. The Panasonic FV-11VQL5 WhisperLite 110 CFM Ceiling Mounted Fan/Light Combination is covered by a manufacturer warranty for period of three years from the date of the original purchase and is sold one item per package.
