air curtains
Doorway wind streams
Air curtains are devices mounted above doorways that blow a continuous stream of air downward, creating an invisible barrier between indoor and outdoor environments.
They keep climate-controlled air in and insects, dust, and outside temperatures out while allowing people to pass through freely: The restaurant installed an air curtain at the entrance to keep flies out during summer.
