1.What is a Barriera d'aria per porte girevoli?

A revolving door air curtain is installed above or beside revolving doors to create a high-velocity air barrier. This barrier prevents outside air, polvere, and insects from entering while maintaining the indoor climate. By minimizing heat or cold air exchange, the air curtain reduces energy consumption and enhances indoor comfort and cleanliness. It is widely used in commercial buildings, office complexes, hospitals, and other places with frequent door usage.
