ACEDUROBLA 4-Inch Metal Exhaust Fan — Window/Wall Mount Ventilation with Check Valve

ACEDUROBLA 4-Inch Exhaust Fan: Durable, versatile ventilation you can install where you need it

Meet a compact metal vent fan designed to move air efficiently in a variety of spaces. The unit uses a sturdy metal housing that resists wear and supports stable performance in environments like attics, basements, bathrooms, kitchens, and garages. With a 4" duct and an accomplished airflow of 117 CFM while drawing only about 20 watts at 110 volts, it balances power and energy use for continuous venting.

The built-in check valve adds a practical layer of control. You can opt for exhaust-only airflow when odors or heat need to escape, or enable a reversible flow as your space requires. When airflow stops, the valve can automatically close with a spring, helping to reduce drafts; if you prefer, the valve can be removed without complicated changes.

Installation is designed to be flexible. This wall-mounted fan can be embedded into a window or mounted on a wall, and it can be used with or without a plug depending on your electrical setup. A compact, slim panel keeps the footprint discreet, making it suitable for tight nooks in homes, grow tents, offices, or utility rooms.
