The purpose of an air blower on doors, commonly known as an air curtain or air door, is to create a barrier of air across an open doorway. These devices blow a controlled stream of air downward, creating an invisible curtain that separates two different environments. The continuous flow of air serves several purposes:

  1. Temperature control: Air curtains help maintain indoor temperature by preventing the exchange of air between two areas with different temperature conditions. In commercial settings, they are commonly used to keep cold air conditioned spaces separate from warmer ambient air, especially in entrances or openings that experience frequent traffic.

  2. Energy efficiency: By creating a barrier of air, air curtains minimize the transfer of heated or cooled air from one space to another. This reduces the loss of conditioned air, which in turn improves energy efficiency by reducing the workload on heating and cooling systems. It helps to keep the interior environment comfortable while minimizing energy consumption.

  3. Insect and pest control: Air curtains can act as a deterrent to flying insects and pests by obstructing their access into a building. The continuous stream of air creates an obstacle that makes it difficult for insects to pass through the doorway, reducing the likelihood of infestations.

  4. Dust and debris prevention: The air curtain's airflow can help prevent the entry of dust, airborne particles, and debris into a controlled environment. By creating a barrier of air, it acts as a shield to keep contaminants from entering the space, contributing to a cleaner and healthier indoor environment.

  5. Comfort and convenience: Air curtains can provide a more comfortable indoor environment by reducing drafts near open doors. They create a barrier that minimizes the entry of outside air, thereby reducing cold or hot drafts that may cause discomfort for occupants near entrances.

Air curtains are commonly used in commercial settings, such as retail stores, restaurants, hospitals, and industrial facilities. However, they can also be found in certain residential applications, particularly in areas with extreme climates or where energy efficiency is a priority.

It's important to note that air curtains should be properly sized, installed, and maintained to ensure optimal performance and effectiveness in achieving their intended purposes.
