Panasonic WhisperCeiling 290 cfm Fan

So Quiet You Might Not Know it's On
WhisperCeiling fans feature a totally enclosed condenser motor and a double-tapered, dolphin shaped bladed 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 it's 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 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. 

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

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. Loose fill or batt insulation can be placed directly over the fan housing to prevent heat from escaping.
