How to Choose Automatic Air Curtain?
As a professional supplier of automatic air curtains, we have summarized a targeted purchasing guide for you.
Measure Door Width
You need to match the length of the air curtain according to the actual width of the door. Make sure the length of the air curtain can fully cover the entire door width to ensure a complete isolation effect and avoid any blind spots in the airtight area. For extremely wide door openings, you can use multiple air curtains in combination.
Installation Height
The installation height of the equipment directly determines the required wind speed and air flow. The higher the installation height, the higher the required wind speed. This ensures that the airflow can reach the ground steadily, thereby forming a complete airtight barrier. For different installation heights, you need to select air curtains with different air volumes to avoid the failure of the isolation effect.
Usage Environment
For indoor enclosed spaces, you can choose the conventional energy-saving and quiet models. However, for semi-outdoor entrances, open environments with large temperature and wind force variations, you can choose enhanced, dust-proof, and weather-resistant models to adapt to the complex external environment and ensure the long-term stable operation of the equipment.
Control Methods
You should choose the corresponding control combinations according to the intelligent management requirements of the building. For ordinary retail and catering scenarios, a combination of door magnetic sensors and remote control is recommended. For intelligent office buildings and industrial parks, a building automation system and timed control are suitable to meet the unified intelligent management requirements.
