Negative air compressor usually refers to a device that can generate negative pressure (i.e. pressure lower than atmospheric pressure), which can be used in various industrial applications. A negative air compressor reduces the air pressure in a closed space by extracting air or other gases, thereby creating a negative pressure environment. This type of equipment has a wide range of applications in ventilation systems, air purification, medical equipment, laboratory equipment, industrial manufacturing processes, and more.
The working principle of a negative air compressor is similar to that of a vacuum pump, which can be achieved through different technologies such as fans, blowers, or more complex mechanical pumps. In some cases, a negative air compressor is also known as an exhaust fan or exhaust fan.
In specific application scenarios, negative air compressors can help control the emission of harmful gases, smoke, steam and other pollutants, maintain indoor air quality, and help improve production efficiency and safety. For example, in hospital operating rooms or isolation wards, using negative air compressors can prevent pathogens from spreading to other areas; In industrial production processes, it can be used to remove harmful gases or smoke and protect the health of workers.
