Types of Air Curtains

Depending on the application and the intent of the space, there are two major types of air curtains to choose from: non-recirculating (most common) and recirculating. Berner offers air curtains for both types to ensure that you find the right solution for every application.


Non-recirculating types of air curtains are more widely used than the recirculating type because they are easier and less expensive to install and have lower maintenance costs. The height, width, and physical characteristics of the opening will indicate if the air curtain can be mounted horizontally above the door or vertically on one or both sides of the door. A horizontal mounting above the door minimizes the chances of damaging the air curtain. Use caution when mounting a unit vertically.

Berner offers multiple product lines that feature non-recirculating air curtains, including:

  • Architectural: beautifully designed air curtains that protect the space while integrating seamlessly into the building design
  • Commercial: designed to meet the functional needs of the application, integrate into the space while keeping installation costs to a minimum
  • Sanitation Certified: EPH Listed to NSF 37 air curtains chosen by restaurants and kitchen designers for chemical-free flying insect control and energy savings
  • Industrial: workhorse air curtains used by manufacturing plants, distribution centers, and warehouses to keep temperatures stable and flying insects out

Recirculating air curtains are typically used in places with constant foot traffic such as supermarkets and store entrances. Berner’s recirculating air curtains are called Air Entrance Systems, as they are built into the entrance, usually when the entrance is being constructed. They emit air from a discharge grille on one side of the door opening, collect it through a receiving grille on the opposite side and returning it through duct-work to the discharge grille. The non-obtrusive wide stream of low-velocity air created by recirculating air curtains is more desirable for separating environments.

At Berner, we have been manufacturing air curtains in the U.S. since 1956, giving us the knowledge and expertise to help a range of industries and applications. Let us help you create safe and comfortable environments
