An air curtain machine uses a high-speed motor to drive a flow-through or centrifugal impeller to generate a powerful airflow, forming an invisible curtain of air. Therefore, it is also called an air curtain machine, air curtain, air curtain machine, wind gate, or air door. English name: air curtain, airdoor.
Air curtains use high-speed motors to drive axial or centrifugal impellers, generating a powerful airflow that forms an invisible curtain. Therefore, they are also called air curtains, air doors, or air screens. English names: air curtain, airdoor.
Applications
Air curtains are installed above entrances in places such as shopping malls, theaters, hotels, restaurants, conference halls, cold storage rooms, operating rooms, and homes that require refrigeration, air conditioning, dust prevention, and insulation. When activated, they separate indoor and outdoor air, allowing for convenient entry and exit while preventing the exchange of hot and cold air. They also offer dust, pollution, and insect prevention. Widely used in electronics, instrumentation, pharmaceuticals, food, precision processing, chemicals, footwear, services, and commercial industries.
Features
Air curtains generate high-speed airflow, dividing indoor and outdoor spaces into two independent temperature zones. This creates a comfortable indoor environment, maintaining the effectiveness of indoor air conditioning and purification, saving energy, promoting air circulation, and effectively isolating dust, smoke, odors, insects, and microorganisms. Preventing the outflow of cold (warm) air and saving energy. The continuously formed air curtain effectively prevents the leakage of cold (warm) air, saving energy, and dividing indoor and outdoor spaces into two independent temperature zones. During prolonged air conditioner operation, it assists in temperature regulation through circulation, saving energy and improving the environment. Dust and insect prevention. The high-speed airflow creates a protective barrier, effectively blocking outdoor dust and insects, maintaining indoor cleanliness. Smoke and harmful gas prevention. The air circulation system strongly blocks the spread of oil fumes, spicy odors, and industrial waste gases and vehicle exhaust from entering the indoor environment. Air circulation. In large spaces such as stadiums, cinemas, and entertainment venues where air conditioning energy distribution may be uneven, the air curtain's circulation system ensures even indoor temperature.
Functions
Heat Insulation Function
Air curtains are mainly used in places where customers frequently enter and exit and doors are constantly opened and closed, such as restaurants, shops, and entertainment venues. This maintains indoor temperatures with 60-80% efficiency, allowing only minimal temperature fluctuations.
Insect Prevention Function
Most annoying and harmful insects are unable to pass through the air curtain, maintaining hygiene in areas such as fruit counters and fast-food restaurants.
Heating Function
Air curtains also include electric heating models, typically using PTC heating, and water heating models. Both types raise the temperature at entrances, commonly used in northern regions, with temperature increases ranging from 30 to 60 degrees.
Dust Prevention Function
Installing air curtains in precision machinery factories or at the entrances of food stores or clothing stores facing bus routes effectively shields outside dust, maintaining cleanliness at a 60-80% level.
Preservation Function
Air curtains prevent odors from chemical laboratories, storage rooms, and meat freezers, and block harmful gases from vehicles. Experts suggest that combining air curtains with air conditioners effectively addresses the issue of cold/warm air leakage.
Negative Ion Function
Produces active oxygen, improves lung function, promotes metabolism, improves sleep, kills bacteria, creates fresh air, removes smoke and dust, prevents myopia and static electricity, and prevents split ends.
