The naming convention for air curtains is: Natural air curtains all start with FM. Major national brands of natural air curtains, such as "FM1209" or "FM1509", where "FM" is an abbreviation for "air curtain"; "12" and "15" indicate the impeller diameter (the larger the impeller diameter, the greater the air volume. There was also an older model with a 09 diameter, typically used for heights of 1.8-2.5 meters. Generally, the required height for installing an air curtain is higher, and the low setting of a 12 or 12.5 air curtain is equivalent to the normal airflow of a 09, so 09 is gradually being phased out); the two digits indicate the length of the air curtain (e.g., 09 indicates a length of 0.9 meters, 12 indicates a length of 1.2 meters). As for the letters after the air curtain length numbers, they generally serve to distinguish the personalized series names of major products. In contrast to natural air curtains, hot air curtains or water-heated air curtains often start with "RM".

Generally, the required installation height of the air curtain will also be higher, and the small gear wind of 12 or 12.5 is equivalent to the normal wind force of 09, so 09 is gradually being screened); the two digits indicate the length of the air curtain (e.g., 09 indicates 0.9 meters in length, 12 indicates 1.2 meters in length). The letters after the number of the air curtain length are generally used to distinguish the individual series names of various products. Compared with natural air air curtains, hot air curtains or water-heated air curtains mostly start with "RM".
Generally, the cold air infiltration load of the door is calculated first, and then the impeller type and impeller diameter of the air curtain are selected according to the size and height of the door. We will select the type based on the width and height of the door, combined with the local actual temperature and wind force. The width of the door is used to determine the size of the air curtain, and the height of the door is used to determine the air supply type of the air curtain. For doors exceeding 3 meters in height, centrifugal air curtains are selected; for doors below 3 meters, axial flow air curtains are selected; for door widths of 2000mm, two 900~1000 units can be selected, or one 1800~2000 unit can be selected. The main specifications of air curtains are 900mm, 1000mm, 1200mm, 1500mm, 1800mm, 2000mm; according to the cooling and heating methods of the air curtain, they are divided into water-cooled, water-heated, water-vapor, and electric heating, etc;
Air curtains are mainly used in conjunction with air conditioners as an auxiliary energy-saving and environmentally friendly device. As long as an air curtain is installed, the heat from the body of the passing crowd can be dispersed, reducing the burden on the air conditioner and bringing a refreshing feeling.
The selection of air curtains is mainly based on the brand. There are many manufacturers in the market, and large brands have many years of production experience and technological accumulation. Their products have been tested by the market, with superior quality and more stable quality. Their services and after-sales service are also more complete. Suitable models can be selected according to needs. Air curtains can prevent odors from escaping from places such as chemical laboratories, shops, storage rooms, and meat freezing machines. They can also prevent harmful gases emitted by vehicles outside. Regarding how to prevent the outflow of cold and hot air from air conditioners, experts suggest: Air curtains and air conditioners can be used together to effectively solve the problems of cold and hot air outflow. The negative ion function produces active oxygen, improves lung function, promotes metabolism, improves sleep, kills bacteria, produces fresh air, removes smoke and dust, prevents myopia, static electricity, and prevents hair splitting.
