An "Air Cutter" is a device designed to create a focused stream of air, often used in various applications such as cooling, drying, or cleaning. It typically consists of a fan or blower that directs air through a narrow opening, increasing the velocity of the airflow. This technology is commonly found in tools like air compressors and industrial blowers. In addition to industrial uses, air cutters are also utilized in household appliances, such as hair dryers and vacuum cleaners. They help improve efficiency by concentrating airflow, making tasks like drying hair or removing dust quicker and more effective.
