WhisperFit 80 CFM Exhaust Fan Low-Profile Housing for Smaller Ceiling Cavities Do you have 2″ x 6″ joists in your ceiling? Are you having trouble finding a ventilating fan that will fit in this small cavity? Well, this model was made just for you. Designed to fit 2″ x 6″ joists or larger, this low-profile fan doesn’t sacrifice performance for size. An optional 3″ duct adaptor1 is also included for those areas where a smaller duct is necessary. So Quiet You Might Not Know it’s On This WhisperFit fan features a totally enclosed condenser motor and a large, double suction 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. The blower wheel is also designed to draw air in from both sides, which helps keep the noise down, as there is more area for the air to enter the wheel. In fact, 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
