A hot air curtain is a device that uses electric heaters or steam heaters to generate hot air, creating an air curtain to block the exchange of air between indoors and outdoors, thus reducing the impact of frequent entry and exit on temperature. Its principle is to blow hot air from the top or side air outlets to form an air barrier that prevents outside air from entering the room while reducing indoor air loss.

The installation of the FM and RM series air curtains is the same. Simply loosen the positioning screws on the bottom front of the unit, separate the unit from the base plate, and then securely fix the base plate to the door frame or wall (loose fixing will cause vibration and noise). Hang the unit directly on the floor, and then use the removed positioning screws to fix the unit to the base plate.

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".

Air curtains can effectively prevent outdoor dust and insects from entering.
Air curtain machines use high-speed motors to drive axial or centrifugal fans, generating a powerful airflow that forms an "invisible curtain" of air for purification. They are also known as air curtains, air screens, air doors, or wind gates. The high-velocity airflow effectively blocks outdoor fumes, odors, and dust from entering, maintaining a clean and comfortable indoor environment. Before the use of air curtains, people relied on solid doors to separate spaces.
