What is the air curtain?

Door air curtain, also known simply as an air curtain, is a device used to create an invisible barrier of air across a doorway or entrance. It’s designed to help maintain indoor climate control by preventing the exchange of air between the interior and exterior of a building when a door is open.

Here are the key features and purposes of door air curtains:

Air Flow: An air curtain blows a controlled stream of air across the width of an opening, creating a barrier. This air barrier helps to prevent the entry of outside air, pollutants, insects, and dust while allowing for the unimpeded movement of people and goods.

Temperature Control: One of the primary purposes of air curtains is to minimize temperature fluctuations when doors are open. In cold climates, air curtains can help retain heated indoor air, and in warm climates, they can help keep conditioned air inside.

Energy Savings: By reducing the infiltration of outside air, air curtains contribute to energy savings by minimizing the load on heating or cooling systems. This can lead to improved energy efficiency and cost savings over time.

Insect and Pest Control: Air curtains are effective in preventing the entry of insects and pests into a building, making them particularly useful in environments where maintaining a sanitary and pest-free space is crucial.

Comfort and Safety: Air curtains can enhance the comfort of building occupants by reducing drafts near doorways. Additionally, they contribute to safety by maintaining clear visibility through doorways, reducing the likelihood of accidents.

Various Applications: Air curtains find applications in a variety of settings, including commercial spaces, industrial facilities, retail stores, restaurants, and healthcare institutions.

Air curtains can be electrically heated, unheated, or heated with hot water or steam, depending on the specific needs of the application. When considering an air curtain, it’s important to choose the appropriate size and type based on the dimensions of the doorway and the environmental conditions of the location.
