This through-the-wall ventilation fan is built for bathrooms, garages, laundry rooms, and storage areas needing steady air exchange. A sturdy AC motor spins at 1486 RPM to deliver up to 110 CFM of airflow while staying quiet at 46 dB or below, measured at 1 meter, so it won't disturb rest or sleep. The 6.3 inch fan fits walls from 4.9 to 6.3 inches thick without a hose, or 7.67 to 10 inches thick with the included aluminum foil hose, giving it flexibility across wall setups. Installation is quick thanks to a full accessory set and a panel with pre-drilled holes for marking and drilling. At 9.72 x 9.72 x 5.71 inches and just 2.65 lbs, the white plastic PP panel keeps the unit lightweight. Since it's designed for indoor use, keep it out of direct rain to protect its lifespan while it keeps bathrooms, laundry rooms, and storage spaces fresh.
