PANA 80CFM 22.8W 0.3 SONES 4" DUCT EXHUSTA FAN

You can be sure the WhisperCeiling series of exhaust fans are super quiet - even in homes with longer and more complicated duct runs. In fact, it's so quiet, you might not know it's on. These fans feature a wide double suction blower wheel and totally enclosed condenser motor for long-life, energy efficiency and quiet operation. The wide double suction blower wheel moves large amounts of air at reduced RPM's and is 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.
