Air Shutter, also known as an air curtain, is a device that uses high-velocity air flow to create an invisible barrier, or "curtain," across an opening, such as a doorway or window. It acts as an invisible shield that separates two environments with different temperatures, humidity levels, or air qualities, without the need for physical barriers. This device has gained significant attention in various industries due to its ability to improve energy efficiency, maintain cleanliness, and enhance comfort. In this article, we will explore the working principles, applications, benefits, and future potential of Air Shutter systems.
