Air curtains

Key Features and Functions:

1. High-Velocity Air Stream: Air curtains produce a powerful and continuous stream of air that flows downward from the top of the doorway to the floor. The velocity of the air stream creates a barrier that prevents external air from entering the conditioned space while allowing people, vehicles, and goods to pass through freely.
2. Mounting Options: Air curtains are available in various mounting configurations to suit different door types and installations. Common mounting options include surface-mounted units, recessed units, and units integrated into door frames or vestibules.
3. Fan or Blower Unit: The core component of an air curtain is the fan or blower unit, which generates the airflow across the doorway. Fans may be centrifugal or axial-flow type, depending on the design and performance requirements of the air curtain.
4. Heating Elements (Optional): Some air curtains incorporate electric heating elements or hot water coils to provide supplementary heating to the airflow. Heating elements help to maintain indoor comfort by offsetting heat loss through the open doorway during colder weather conditions.
5. Adjustable Airflow: Many air curtains feature adjustable airflow settings, allowing users to control the velocity and direction of the air stream to match the specific requirements of the doorway and surrounding environment. Adjustable airflow settings provide flexibility in balancing energy efficiency with effective door sealing.
6. Automatic Activation: Air curtains may be equipped with sensors or switches that automatically activate the unit when the doorway is opened and deactivate it when the doorway is closed. Automatic activation helps to ensure continuous operation without the need for manual intervention, enhancing convenience and energy savings.
7. Energy Efficiency: By creating an invisible barrier of air, air curtains help to reduce the transfer of heat or cold air between indoor and outdoor environments, thereby improving energy efficiency and reducing heating and cooling costs. Energy-efficient air curtains contribute to maintaining stable indoor temperatures and minimizing HVAC system workload.
8. Noise Reduction: Modern air curtains are designed to operate quietly to minimize noise disturbance in indoor environments. Low-noise fans, sound-absorbing materials, and vibration-damping features help to reduce operational noise levels, ensuring a comfortable and quiet indoor environment.
9. Air Quality Improvement: Air curtains help to enhance indoor air quality by preventing the ingress of outdoor pollutants, dust, insects, and airborne contaminants. By creating a barrier of clean air, air curtains contribute to maintaining a hygienic and comfortable indoor environment for occupants.
