How does an air curtain work?

An air curtain, also known as an air door, works by creating a barrier of high-velocity air that separates two different environments, such as indoor and outdoor spaces or two differently conditioned areas within a building. They are commonly used over entrances to buildings or openings in industrial settings to help maintain desired indoor temperatures, keep out insects and pollutants, and prevent the entry of dust and debris.

### How Does an Air Curtain Work?

1. Air Flow:

– An air curtain unit typically contains a fan or blower that pulls in air from the surrounding environment.

– The air is then propelled at high speed through a nozzle or vent located at the entrance or opening where the air curtain is installed.

2. Barrier Formation:

– The high-velocity air stream acts as a barrier between the interior and exterior environments, effectively sealing off the two spaces.

– This barrier helps to prevent the exchange of air, maintaining temperature control and reducing energy loss.

3. Benefits:

– Energy Efficiency: By preventing the escape of conditioned air, air curtains help reduce heating and cooling costs.

– Pest Control: They can deter insects and airborne contaminants from entering a building.

– Comfort: Air curtains create a more comfortable indoor environment by minimizing drafts near entrances.

4. Installation:

– Air curtains can be mounted horizontally above doorways or vertically alongside larger openings.

– Proper installation is crucial to ensure effective air flow and coverage across the opening.
