What’s an Air Curtain?
air curtain (n.) also known as: air door, air barrier, air screen
An air curtain is a machine that blows a controlled, high-velocity stream of air across an opening to create an invisible air seal. This seal separates two environments on either side of the opening while allowing an uninterrupted flow of people, vehicles, and goods.
Because it contains heated or cooled air inside the building, an air curtain delivers significant energy savings and improved personal comfort in both industrial and commercial settings. It also blocks the infiltration of flying insects, dust, fumes, odors, and other airborne contaminants without requiring any physical barrier at the door.
Berner air curtains are designed, engineered, and manufactured in the United States, with units optimized for the specific velocity, spread angle, and coverage requirements of each application type.
Cómo funciona una cortina de aire
Las cortinas de aire crean una barrera invisible que separa los ambientes al tiempo que permite que las personas se muevan libremente.
Aire aspirado hacia la unidad
El aire ambiente es aspirado hacia la cortina de aire y acelerado por ventiladores internos.
Se crea una corriente de aire controlada.
La unidad proporciona un flujo de aire uniforme y de alta velocidad a lo largo de todo el ancho de la abertura.
Se forma una barrera invisible
Esta corriente de aire crea un sello hermético que ayuda a mantener separados los ambientes interior y exterior, reduciendo la transferencia de contaminantes y la pérdida de temperatura.
Resultado: Comodidad y eficiencia
El aire acondicionado se mantiene donde debe estar, se evita la entrada de plagas y partículas en suspensión, y el tráfico fluye libremente sin barreras físicas.

2 Types of Air Curtains
Non-Recirculating (Most Common)
Non-recirculating air curtains draw in ambient (natural) air from above the opening, project it downward, and allow it to dissipate at the floor. Horizontal mounting is preferred to minimize the risk of damage in high-traffic environments.
Caracteristicas claves
- Más fácil y menos costoso de instalar
- No ductwork required. Simpler, faster install
- Lower initial cost and lower maintenance overhead
- Horizontal or vertical mounting configurations
- Right choice for most commercial and industrial openings

Recirculating (Air Entrance System)
Recirculating air curtains emit air from a discharge grille on one side of the opening and collect it through a receiving grille on the opposite side, then return it via ductwork to the discharge grille.
Caracteristicas claves
- Más fácil y menos costoso de instalar
- Wide, low-velocity stream, most unobtrusive barrier
- Discharge and return grilles integrated into the structure
- Best specified during design or construction phase
- Ideal for supermarkets, flagship retail, and public facilities
