The cross flow air curtain is a slim and high-efficiency air isolation device specially designed for commercial and indoor entrance ventilation solutions. Adopting professional cross-flow fan wheel structure, this air curtain forms a continuous and dense vertical air barrier at door openings, effectively isolating indoor and outdoor air circulation without obstructing pedestrian traffic and daily logistics access. It is widely applicable for supermarkets, retail stores, office buildings, hotels, restaurants, exhibition halls and small and medium-sized commercial spaces. Capable of blocking external dust, flying insects, odor and humid air while locking indoor cold or warm air, it serves as an ideal energy-saving ventilation accessory for maintaining indoor constant temperature, cleanliness and comfort.
