National 3-Feet Air Curtain

This National 3-feet air curtain is a fan-driven device used above doors to efficiently separate two different environments by creating an invisible air barrier. This air curtain is designed with 110W rated power to operate. Usually, this air curtain is used in large areas like auditoriums, assembly halls, and mosques to maintain a cool temperature balance in the room when a door is opened. It protects against ingress of smoke and toxic fumes.
