It also prevents insects and dust from entering inside to ensure clean air in the room. It is normally used at the Entrance and exit of commercial premises, like shopping mall, airports, hotels, restaurants, and industrial factories. So it is very important to choose the suitable air curtain, and I promise the followed 10tips will very useful.

1. 문의 높이

  • The airflow needs to cover the whole length of the door(from top to the floor) to ensure air curtain work efficiently if the airflow is too weak, the outside air will come inside from the bottom of the door. for instance, the door height is less than 3m, we recommend cross-flow type air curtain. the door height is more than 3m, centrifugal type air curtain is required.

2. 문의 너비

  • The air curtain length should be the same or a little wider than the door opening width, so the outside air can not go inside from the two sides of the door. the standard air curtain length is 900mm,1200mm 1500mm 18000mm,2000mm, if the door width is more than 2m width, we can use several air curtains in a row.

3. 추가 기능

  • UV lightso some special places,such as hospitial uv light air curtain is highly need. and there two years more and more places require this beacuse of the covid-19.
  • Door sensor, it can save energy when using door sensor or magnetic switch. Normally it is equipped with automatic door.

6. 설치공간

  • Top installation,normally we install air curtain on the top of the door, as it can save cost and space.
  • Vertical installationwhen there is no enough space on the top of the door, then we can use vertical type air curtain. put air curtain on each side of the door.

7. 회전형 도어 에어커튼

8. 소음 수준

On different occasions, people’s sensitivity to sound is different. For example, in factories, the environment is noisy, then the sound requirements will not be very high, then we can choose centrifugal type air curtain . But if in office buildings or hotels, air curtain running sound is too loud, often it will affect people’s work and rest. so we need to choose cross-flow type air curtain.

9. 설치환경

  • For Humid environment, then we need to choose SS304 air curtain with aluminum impeller.
  • If we install the air curtain for the cold storage room, then we need to install the outside of the door to avoid the broken

  • High volume air curtain , In the same condition, it is not the right choice to use the high-volume air curtain. When you choose the High air volume, you choose the loud noise at the same time.
  • The higher airspeed, the better barrier effect, but in fact, in the same condition, when you choose the higher speed, the air will reflect on the ground, then it will lose the barrier effect.
