Negative pressure isolator is a device used to control the direction of air flow, often used in medical institutions and laboratories and other places, its main role is to prevent the spread of harmful substances or pathogens in the air, effectively protect the safety of personnel and the environment.

 The negative pressure isolator usually consists of a negative pressure system, a filter, an exhaust outlet, etc. When the equipment is working, the air is purified through the filter, and then it is pumped out and put into the external environment, and the external air is not allowed to enter the inside of the equipment. This negative pressure mechanism effectively avoids the diffusion of pollutants in the air and improves the safety of the workplace.

 In medical institutions, negative pressure isolators are often used to isolate patients with infectious diseases, such as tuberculosis, influenza, etc., which can effectively control the spread of pathogens and protect the safety of medical staff and other patients. In addition, negative pressure isolators can also be used in workplaces dealing with harmful chemicals, radioactive substances, etc., to protect the health and safety of workers.

 The use of negative pressure isolators should be in strict accordance with the operating procedures, and the operating status of the equipment and the cleanliness of the filter should be regularly checked during use to ensure the normal operation and effective protection of the equipment. In addition, during the use of the equipment, the staff also need to pay attention to maintain a certain distance from the equipment to avoid the impact on the equipment.

 Overall, negative pressure isolators are an important safety device that plays a key role in protecting the safety of people and the environment. In the future development, we should continue to improve the performance and technology of the equipment, improve its applicability and safety, and be widely used in different fields to provide better protection for people's health and safety.
