Vertical Air Curtain
[INQ. NO. 2511C06] The Vertical Air Curtain by ALLAIR is an advanced air-blocking system designed to maintain clean, energy-efficient environments in industrial and commercial spaces. Installed on both sides of doorways, it prevents the loss of conditioned indoor air while blocking dust, insects, and external contaminants.
This vertical design improves energy efficiency and air quality, making it ideal for logistics centers, freezer warehouses, and large-scale distribution hubs.
The product achieves maximum energy-saving effects through the horizontal injection of high-speed air from both upper and lower sides, effectively suppressing cold-air outflow and external air inflow. Its Sirocco fan structure enhances air volume and velocity while minimizing noise, ensuring powerful performance without sacrificing comfort.
The built-in motor-integrated body increases rigidity and reduces vibration, contributing to the product’s long-term durability.
Constructed from stainless steel (STS 304), the vertical air curtain maintains exceptional corrosion resistance and structural stability, even in humid or temperature-fluctuating environments.
The system’s oblique air-discharge design at a 3° angle minimizes condensation caused by temperature differences between indoor and outdoor spaces, helping prevent frost and moisture buildup inside cold storage areas. Its damper-combined grill offers safety and practicality by blocking dust accumulation while providing an aesthetically clean appearance.

With a discharge speed of 25 m/s, air volume of 280 m³/min, and power consumption of 3.5 kW, the unit provides strong yet efficient air separation for entrance doors up to 3.6 meters in height. The product’s fan interlocking function allows it to automatically operate according to door movement, enhancing convenience and reducing unnecessary energy use. This intelligent control makes it a sustainable choice for facilities prioritizing environmental responsibility.

The Vertical Air Curtain has earned praise across various industries such as food processing plants, refrigerated storage facilities, cosmetics manufacturing centers, and logistics warehouses.
By maintaining stable indoor temperatures and preventing the infiltration of polluted air, it contributes to product safety, hygiene management, and improved workplace comfort. Its proven reliability and adaptability have positioned the product as one of the most efficient air-blocking solutions in the market today.

Through continuous innovation, the company also applied for a patent (No. 2022-0017907) related to the air-curtain device for freezer warehouses, demonstrating its commitment to developing technology tailored to specialized industrial environments. The design’s precision engineering ensures consistent performance and easy customization according to site conditions, enabling the delivery of custom-made solutions that meet diverse customer needs.
