This is an in-line duct fan designed to be installed directly into your ventilation ductwork. It operates on a 110V power supply and is available in two sizes: 4 inches and 6 inches in diameter.
The fan's main purpose is to boost airflow and improve circulation. It can be used as an exhaust fan to pull stale, humid, or smelly air out of a room, or as a ventilation fan to bring fresh air in. Its versatile design makes it suitable for various applications, including:
 
Bathrooms and toilets: To remove steam and odors.
Kitchens: To vent cooking fumes and heat.
Windows and walls: To improve general air circulation in a room.
Since it's installed inside the duct, it provides a powerful, yet relatively quiet, solution for moving air from one point to another.
