From the Manufacturer
Panasonic WhisperWarm Ceiling Mounted Fan/Heat Combinations are smaller, quieter, warmer, and easier to install. A tubular, stainless-steel-sheathed heating element features Nichrome wire with magnesium oxide for optimal heat transfer and electrical insulation at elevated temperatures. The Panasonic FV-11VH2 WhisperWarm 110 CFM heater/fan has a totally enclosed condenser motor and a large, double suction blower wheel to quietly move air. The blower wheel is designed to draw air in from both sides allowing more area for the air to enter the wheel. Panasonic fans are quiet enough that you might not even know they're on. With a .6 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 fan has a built-in damper to prevent back draft, which helps to prevent outside air from coming through the fan. The Panasonic FV-11VH2 WhisperWarm 110 CFM Ceiling Mounted Fan/Heat 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.
