Air curtains are powerful air streams generated by impeller fans, creating an invisible curtain of air, hence also known as wind curtain machines, air curtain machines, air flow curtain machines, wind gates, air doors, and wind door machines.
For use at the entrances of shopping malls, theaters, factories, hotels, and restaurants, etc., featuring refrigeration, air conditioning, dust prevention, and insulation.
The air curtain, also known as the wind curtain machine, was first introduced to China from two countries: the former Soviet Union and Japan. The Soviet Union introduced a heated air curtain, primarily used in northern China to provide insulation and warmth during winter.
Clean
For food factories, cafeterias, and other clean environments, air curtains are even more crucial. We all know that effectively blocking the entry of mosquitoes and flies is vital for clean spaces. Using air curtains to block mosquitoes and flies is the most effective method. Its working principle involves maintaining a high air flow at the opening of the door, creating a local high wind speed and high air pressure, which prevents mosquitoes and flies from entering. The key points of use also involve two elements:
1. During the installation of the wind speed top-blow system, a wind speed of over 4m/s at a height of 1 meter from the ground is required to effectively block the entry of mosquitoes and flies. For the double-sided blow installation, when a single unit is operating, the wind speed at the center of the door opening should exceed 4m/s. For the single-sided blow installation, the wind speed must be greater than 4m/s when reaching the opposite side.
2. Ensure the full width of the doorway is open for continuous air flow. For instance, if the doorway width is 2 meters, when selecting a model with an air curtain that offers continuous air flow, you can choose one 0.9-meter and one 1.2-meter long air curtain. Avoid using an air curtain model that does not offer continuous air flow. Additionally, it should meet the requirements for the specified airspeed.
