air curtains are installed over doors to provide a barrier of air that helps to keep out dust, insects, and other contaminants.
They can be used in both residential and commercial settings, and are often seen in places like hospitals and food processing facilities.
Air curtains work by creating a constantly moving stream of air that is directed across the opening of a door.
This air flow creates a pressure difference on either side of the door, which makes it difficult for outside air to enter the room.
In addition to their primary purpose of controlling air flow, air curtains can also help to reduce noise levels and energy costs.
By keeping doors closed, they prevent air from escaping, which can help to keep rooms cooler in the summer and warmer in the winter.
As a result, air curtains can provide both functional and economic benefits.
