The air curtain device is positioned on the top or side of the entrance and covers the entire door section with the air flow created and prevents the hot - cold or dirty air that may come into the environment from outside, as well as the negative factors of the external environment (dust, flies, smoke, humidity, etc.) from entering.
A door heater consisting of a low-flow fan and a small capacity heater placed on the door in some stores only heats that area, while an air curtain saves energy by preventing heat escape with the strong current it provides.
In order to get maximum efficiency from the air curtain, there must be air balance in the building. If there is positive or negative pressure in the building, it is not possible for the air curtain to prevent air intake or air escape, but the comfort conditions of the indoor air are maintained as it will allow the incoming air to enter by heating.
What is the advantage?
• Doors Can Stay Open
The invisible curtain created by using fast air flow allows people to easily enter and exit the building without being blocked by the doors. Therefore, the use of air curtains is recommended wherever the door is to be kept open.
• Reduces Airflow and Discomfort
It avoids disturbing staff, customers and visitors near the door from the air flow coming from outside.
• Saves Energy
It is possible to reduce the operating costs of heating and cooling systems with air curtains. It supports the heat insulation system used for energy efficiency in buildings. At the same time, it increases the service life of these devices by ensuring that building heating and cooling systems operate less.
• Improves Indoor Air Quality
The impact of external factors such as insects, pollen, smoke and dust on indoor quality is minimized.

Conditioned air and outdoor air easily mix with each other, causing energy loss and reducing indoor air quality. |
The correctly selected air curtain creates a sharp separation between different temperature zones. It creates a barrier that effectively prevents unwanted air flows. |
(Figure-1) (Figure-2) (Figure-3)
The efficiency of the air curtain is inversely proportional to the internal - external pressure and temperature differences and wind speed. In a proper installation, the airflow generated by the air curtain should cover the entire opening it is installed to protect (Figure-1). If the air curtain is not wide, it cannot generate a large enough air flow to fully protect the opening mounted on top, thus increasing the heating or cooling costs of the space as a result of leakage (Figure-2).The same applies to the height of the air curtain (Figure-3). If the air curtain is oversized for the door to be used, it will result in additional energy use without any additional benefit to the consumer.
