So Quiet You Might Not Know its On WhisperCeiling™ fans feature a totally enclosed condenser motor and a large blower wheel to quietly move air. A small wheel turning very fast will create more noise than a large wheel turning more slowly for a given airflow. Our fan uses a wide blower wheel that moves a large amount of air at reduced RPMs, so it is quiet enough that you might not even know its on. Continuous, Trouble-free Operation for Many Years This fan is designed to give you continuous, trouble-free operation for many years thanks in part to its high-quality components and permanently lubricated motors which wear at a slower pace. Also, since heat is always detrimental to motor life (the cooler the environment, the longer the motor will last), we designed the electrical configuration of this models 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. User-Friendly Installation Detachable adaptors, firmly secured duct ends, adjustable mounting brackets (up to 26"), fan/motor units that detach easily from the housing and uncomplicated wiring all lend themselves to user-friendly installation. This model also features a double-hanger bar system for ideal positioning. Energy Star® Qualified for Energy Savings Energy Star qualified products feature super-quiet operation and high CFM-to-Watt efficiency. The Energy Star program was created to help consumers identify products that can save them money and protect the environment by saving energy. As an Energy Star partner, all our fans are Energy Star qualified and labeled accordingly. Tired of Cold Air Coming Through Your Ventilation Fan? This Panasonic fan has a built-in damper to prevent backdraft, which helps to prevent outside air from coming through the fan. Also, thanks to our efficient, cool running motors and fluorescent bulbs, it does not create excessive heat-a common problem with recessed lighting fixtures and some competitors fan/light combinations. Loose fill or batt insulation can be placed directly over the fan housing to prevent heat from escaping.
