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.

Homes designed and built in recent years are more airtight and energy efficient than in the past. This results in fewer drafts (passive ventilation), which lowers the cost of heating and air conditioning. However, stale air and indoor air pollutants accumulate in an airtight home and can be hazardous to the occupants. Sources of indoor air pollution include biological pollutants such as mold and mildew from excessive moisture, pet dander and pollen. Additionally, chemical pollutants from new building materials, cleaning fluids and various preservatives used in furniture and carpets can accumulate creating a potentially toxic environment in the home. In addition to creating a hazardous air environment, mold and mildew can potentially grow unchecked in wall and ceiling cavities where they can eventually compromise the integrity of the building's internal structure. The first and best approach to creating a clean safe indoor environment is to eliminate or relocate unnecessary sources of pollution. The next step is to ensure that the home has proper mechanical ventilation equipment to address source pollution points like bathroom, kitchen, laundry room and workshop, as well as, proper mechanical ventilation to address accumulated pollutants throughout the home.

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.

Constant CFM Performance This WhisperGreen™ model features built-in intelligence called SmartFlow™ Optimum CFM Technology. This unique "electronic-brain" lets the fan do what was once thought to be impossible, perform at a constant CFM regardless of elbows and other factors that might hinder performance. Basically, when a WhisperGreen™ fan faces static pressure, its speed is automatically increased to ensure that the desired CFM is actually achieved. This allows the fan to perform as rated and makes for easier installation because the installer no longer has to worry as much about compromising the fan's performance. Variable Speed Control This fan is equipped with a CustomVent™ Variable Speed Control. This allows the fan to run continuously at a pre-set lower level of 30-70 CFMs that can then be elevated to a maximum of 80 CFMs when the switch is turned on, or via the SmartAction™ Motion Sensor. A High/Low delay timer(adjustable from 30 seconds - 60 minutes), will then return the fan to the minimum CFM level after a period of time set by the user. So Quiet You Might Not Know it's On This WhisperCeiling™ model 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. 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.
