About Air Curtains
Theodoor air curtains create an invisible barrier when installed above entryways in commercial and industrial settings. They effectively isolate indoor and outdoor environments, maintaining temperature and humidity levels while preventing dust, pests, and fumes from entering. Ideal for use with air conditioning systems, they significantly improve energy efficiency by reducing thermal exchange.
