The WhisperFit™ low-profile ventilation fan can provide up to 90 cubic feet of air movement a minute and has a sound level as low as 0.7 to 1.5 sones, depending on fan size, the company says. It can be used in remodeling and manufactured home applications. The fan housing has a low-profile design and is only 5-1/2-inches deep. According to the manufacturer, since an adapter can be used to decrease the duct size from 4 inches to 3 inches, it allows for the remodeling of 3-inch existing ductwork. All WhisperFit models are Energy Star compliant.
