YGUAYINGC 512M 6-inch Through-Wall Exhaust Fan – 80 CFM, Quiet 4.0 Sones, Corrosion-Resistant Metal Vent Cap, Retractable Duct

Efficient, rugged ventilation for bathrooms, kitchens, and garages

Meet the YGUAYINGC 512M 6-inch through-wall exhaust fan—designed to move air quickly in compact spaces while withstanding tougher conditions. Its copper motor coil is built for longevity, and the exterior wall is engineered to resist rain and wind. A premium metal vent cap adds rust and corrosion resistance, while a backflow flap helps maintain steady airflow by preventing pests or debris from re-entering the space.

It delivers up to 80 CFM for spaces up to about 75 square feet, and it operates at a quiet 4.0 sones, so daily routines aren’t interrupted by loud airflow. Whether placed near a shower, sink, or workbench, the fan aims to support a fresher atmosphere without drawing unnecessary attention.
