Air curtain or air door is equipment that creates an invisible air barrier between the inside and outside environment. It can stop the warm or cold air from coming inside, reduces your electricity bill up to 50% by improving air conditioning efficiency. 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, 空港, ホテル, レストラン, and industrial factories. So it is very important to choose the suitable air curtain, and I promise the followed 10tips will very useful.
1. ドアの高さ
- 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. 例えば, 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. ドアの幅
- 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,2000んん, if the door width is more than 2m width, we can use several air curtains in a row.
3. 追加機能
- UV light，so 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.
4. 加熱または非加熱
- For some cold places, heated function is required, so when people pass the door, they will feel comfortable, according to customer requirements,we have PTC and electrical tube air curtain and water heated air curtain to choose.
5. 電源
- As the power supply is different in each country,such as 220v 50hz , 380v 50hz 3p 1p in China,110v 60hz 1p,220v 60hz 3p in south Amercia. Then we will use the suitable motor for the air curtain.
6. 設置スペース
- Top installation,normally we install air curtain on the top of the door, as it can save cost and space.
- Vertical installation， when 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. 回転式ドアエアカーテン
Normally it is used in Star hotels and upscale offices. so revolving air curtain needs a special beautiful design according to the size of the revolving door. The air curtain color should be the same as the door.
8. 騒音レベル
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. 設置環境
- 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
- For transportation vehicles such as buses, refrigerated trucks, fruit and beverage delivery trucks, then we need to use DC air curtain 12v or 24v. It can save energy and keep the food is fresh.
10. よくある選択の間違い
- High volume air curtain , 同じ状態で, 大容量エアカーテンを使用するのは正しい選択ではありません. 大風量を選択した場合, あなたは同時に大きな騒音を選択します.
- The higher airspeed, より良いバリア効果, しかし実際には, 同じ状態で, 高速を選択した場合, 空気が地面に反射します, そうなるとバリア効果が失われます.
- Choose the entirety heated air curtain, ドアの高さが2mを超える場合, 下部には熱風カーテンを選択できます, 高さ2m以上の部分は非加熱機能も選択可能, そうすれば電力消費を節約できます.
