Air curtain machines are powerful air streams generated by high-speed motors driving through-flow or impeller fans to form an "invisible curtain" of air purification equipment. They are also known as air curtain machines, air screen, air curtain unit, air shutter, and air door. English name: air curtain air door.

The high-speed airflow of the air curtain machine can effectively block outdoor smoke, odors, and dust from entering the indoor space, maintaining cleanliness and creating a fresh, comfortable environment.

Air curtain machines generate a powerful airflow through high-speed motors driving through-flow or centrifugal impellers, creating an "invisible curtain" to divide indoor and outdoor spaces into two separate temperature zones, thus creating a comfortable indoor environment and maintaining the efficiency of indoor air conditioning and purification.

Fruits, while conserving electricity, also facilitates air circulation, effectively isolating dust, smoke, odors, insects, and microorganisms. It prevents the outward leakage of cold (or warm) air, saving energy as well as effectively preventing the escape of cold (or warm) air, dividing the indoor and outdoor environments.

Two independent temperature zones, with auxiliary circulation to adjust temperature during prolonged operation of the air conditioner, aiming to save energy and improve the environment, with dust and moisture prevention effects.

The air curtain generates high-speed airflow, forming a protective door that effectively blocks outdoor dust and flying insects from entering, maintaining indoor cleanliness. The smoke and harmful gas prevention effect: The air circulation system of the air curtain can strongly isolate the spread of smoke, pungent odors, and industrial waste gases, as well as car exhausts and other harmful gases from entering the indoor space. The air recirculation function of the air curtain ensures uniform temperature distribution in large spaces such as gymnasiums, cinemas, and entertainment venues where air conditioning energy distribution is uneven.
