Negative air pressure is a safe containment solution in which more air is taken in than is expelled.
Negative air pressure in the environment does not mean that the actual pressure is negative because, according to science, absolute pressure can never be less than zero. Negative air pressure means that the pressure within an environment is less than the pressure of its surroundings. As air flows from high pressure to low pressure, this difference in pressure level acts as a vacuum effect and causes air to flow in from the outside.
The negative air system produces a vacuum effect or a direction of air flow into the space by creating and maintaining the air pressure differential. In doing so, it restricts the spread of contaminants such as dust and mould and pollutants such as bacteria and viruses from the controlled space to the outside.
This system traps dangerous and infectious particles in the air and removes them by means of a blower and a group of filters.
In summary, when the external environment is safe, but toxic and harmful gases are generated inside, negative pressure is preferred
