Why Use Air Curtains in Business and Industry?

Commercial and industrial air curtains are typically installed at entrances to create a seamless air barrier by continuously ejecting a stream of air with pressure and velocity downward. This makes it possible to keep out external contaminants while allowing easy access for employees and customers. So not only do they help you maintain the interior environment of your commercial or industrial space, but they also safeguard operational and production efficiencies.

Air Curtain Working Principle​

• Air Intake: When the air curtain begins to operate, its fan will draw in air from around the environment through the air intake on one side of the housing. 
• Air Conditioning: Some air curtains add the option of heated or cooled air. You can choose one to achieve a more comfortable experience for your project in cold or hot weather.
• Acceleration: A high-speed motor will drive the wind turbine to accelerate the inhaled air into the air collection chamber. 
• Creating air barriers: The treated air is evenly distributed in the discharge nozzles and ejected in the direction of the length of the air curtain, creating a powerful airflow that reaches the floor and creates a tight, invisible barrier. These barriers fulfil the requirements for barrier-free access while achieving excellent isolation and protection.

What Commercial and Industrial Air Curtains Can Do

Contaminant Blocking

The high-velocity airflow barrier provided by the air curtain acts as a barrier to prevent outside contaminants such as dust, wind, debris and flying insects from affecting the internal environment. It can also be used to prevent environmental exchanges such as temperature and odour in different areas. Therefore, choosing air curtains for applications such as restaurants, warehouses, food processing plants, etc., can help you achieve better standards of hygiene and safety.

Controlling Temperatures

Air curtains are effective in maintaining internal temperatures, blocking the entry of hot, humid air from outside in hot climates, and preventing the entry of cold air and heat loss in cold climates. So using an air curtain at the entrance to a cold store not only keeps the area clean but also reduces temperature fluctuations and prevents damage to goods or mould growth. For shopping malls, offices, etc., it can create a more comfortable and safe temperature environment for your staff and customers.

Save Energy 

You can equip your air-conditioning system with an air curtain to achieve better air-conditioning results. It prevents the loss of air from the air conditioning output. And in places where there is a lot of movement of people, it does not need to be opened and closed as often as a door, allowing the air conditioning system to achieve better efficiency. Therefore, air curtains not only reduce the energy loss of your air conditioner but also extend the life of your air conditioner. This all reduces the cost.

Benefits of Using Air Curtains in Business and Industry

Outstanding Quality

Aosun air curtains are available with aluminium or copper motors and aluminium blades. The housings are made of galvanised steel, stainless steel, or other metals. They provide excellent and stable performance with a long service life. This reduces the risk of damage, repair costs and waiting times, thus guaranteeing the stable operation of your project.

Strong Airflow Barrier

The air curtain delivers powerful airflow at speeds ranging from 6 m/s to 15 m/s for you to choose from according to your needs. This achieves better protection and a cleaner environment for your factories and commercial premises.

Cost Reduction

The air curtain is equipped with PIR sensors or BMS-integrated intelligent controls that allow it to be easily controlled and regulated, thus reducing your labour costs. And you can switch settings at any time to reduce unnecessary energy loss. In addition, it is equipped with an EC brushless motor for 50% energy savings.

Multiple Options

You can choose from a wide range of sizes, air speeds and materials to get the best performance out of your air curtain, depending on your application. You can also choose models with heating for use in cold environments.

Increased Operational Efficiency

Compared to physical doors, they are highly visible, more tightly sealed and do not interfere with access. It is an ideal entrance-protection solution for businesses and industrial facilities. You can benefit from this by increasing the efficiency of your production and operations.

Lower Noise

Air curtains maintain a consistently low noise level (≤55 to 60 dB) during operation. You can use them in sound-sensitive locations, such as hospitals, hotels, and libraries, without compromising the customer experience or interfering with employee productivity.

Typical Industrial and Commercial Applications of Air Curtains

Catering

If you’re choosing the right door curtain solution for a catering outlet or commercial kitchen, an air curtain is a good fit. It prevents the entry of external contaminants (e.g. dust, odours, and car exhaust), enabling you to meet strict hygiene standards and enhance the customer experience.

Commercial Buildings

Air curtains can provide continuous operation in densely populated areas such as shopping centres, offices and supermarkets. They optimise air quality while maintaining quiet operation, enhancing the customer experience and staff productivity for you. They save you money by reducing energy consumption while optimising the efficiency of your air conditioning.

Manufacturing Plants

Air curtains are used in manufacturing plants in industry, especially in food processing plants. On the one hand, they prevent the entry of contaminants that could affect the quality of the product or cause damage to machinery, thus reducing production or maintenance costs. On the other hand, transparent and visualised air curtains make it easy for staff to check the situation at any time to prevent risks.

Warehouses

Both industrial and commercial warehouses require strict air quality and temperature control for good storage and freshness. Air curtains provide good insulation and temperature control to solve this problem. With frequent access, they help reduce temperature loss and fluctuations, ensuring the safety of goods.

Medical Buildings

Air curtains keep out most dust, fumes and foreign matter and maintain temperature stability, providing a clean operating environment in hospitals, laboratories and more. Alternatively, if you require a more demanding environment, the air output from the air curtain is specially sterilised for more specialised bacteria control and purification.

How to Choose the Right Air Curtain for Commercial and Industrial Applications?

Height and Width of the Entrance

Measure the height and width of the entrance to obtain the exact dimensions and select the right air curtain accordingly. This is because only the right installation height ensures that the airflow reaches the floor and achieves tight insulation. You should choose an air curtain with the same or slightly wider width for the entrance to ensure that it completely covers the entire opening. If your entrance is too large for the existing standard sizes, you can use several air curtains in combination.

Select Wind Speed

Select the optimum air velocity of the air curtain while ensuring that it allows the airflow to completely cover the entrance area. Insufficient speed will not achieve a good barrier, resulting in an exchange of air between inside and outside. Excessive air velocity will not only blow air out of the room but may also create unwanted noise and drafts.

Selection of Mounting Method

• Surface-Mounted Air Curtains: Surface-mounted air curtains are hung directly above the entrance. They are very simple to install and much easier to maintain.
• Recessed Air Curtains: If you have enough space in the ceiling of your entrance, you can seamlessly integrate a recessed air curtain above for a more aesthetically pleasing effect.

Other Requirements

Some models are equipped with heaters, making them better able to cope with cold weather. If your project is sound-sensitive, choose an air curtain with a low noise level. Also, if the entrance already has a door, you’ll need to consider the type of door, such as a swinging or sliding door, to choose a different air curtain design for enhanced compatibility.
