How Air Curtains Work
Air curtains create an "invisible air door" using high-speed motors with cross flow or centrifugal blowers. They effectively isolate indoor and outdoor environments while maintaining temperature and humidity. Widely used in electronics, pharmaceuticals, food processing, and chemical industries for environmental control.
