Of those "walls of air" used to divide spaces, usually to prevent heat or cold loss, or to prevent smoke from travelling? They're high-pressure air shooting down from the ceiling, and commonly encountered in public spaces (I know I've encountered them in some restaurants, grocery stores, and our public transit buildings).
