A desk fan is a small, portable device designed to circulate air in a specific area, typically placed on a desk or table. It usually consists of a motor, blades, and a protective grille. Desk fans can be powered by electricity or batteries and come in various sizes and designs to suit different preferences and spaces. These fans are commonly used to provide personal cooling, improve air circulation, and reduce humidity in small rooms or workspaces. They are often adjustable, allowing users to change the direction and speed of airflow. Desk fans are popular in homes, offices, and classrooms for their convenience and effectiveness.
