Factors affecting the service life of gas cartridges

The gas cartridge is one of the main products in respiratory protection, and its service life is affected by a number of factors which together determine the effective protection time of the gas cartridge in practice. What are the factors that affect the life of the gas cartridge? Let's take a look below.

The concentration of toxic and hazardous substances:

The protection time of the gas cartridge is directly affected by the concentration of toxic and hazardous substances. The higher the concentration, the greater the adsorption and filtration load of the gas cartridge, so the shorter the protection time. Conversely, the lower the concentration, the longer the protection time of the gas cartridge.

Mixing of hazardous substances:

If there are multiple hazardous gases in the environment and these gases may chemically react or interact with each other, this will also affect the filtration effect and life of the gas cartridge.

Environmental humidity:

Changes in the humidity of the air in the operating environment can have an effect on the life of the gas cartridge. Unused gascartridges that are improperly stored, resulting in moisture in the filling layer, will have a significantly reduced service life. At the same time, high humidity in the operating environment may cause the adsorbent material inside the gas cartridge to deteriorate, thus shortening its service life.

Ambient temperature:

Ambient temperature is one of the important factors affecting the service life of the gas cartridge. Different gas cartridges have different adaptability to temperature. Some gas cartridges perform better at lower temperatures, while others may perform better at higher temperatures. Therefore, you need to choose the right gas cartridge according to the actual usage environment.

Duration of use:

The longer a gas cartridge is in continuous use, the more saturated its internal adsorbent material becomes, and the weaker the protection becomes. Therefore, the gas cartridge needs to be replaced periodically to ensure continued effective protection.

User's breathing rate and intensity:

The rate and intensity of the user's breathing directly affects the rate at which the gas cartridge is consumed. Users who breathe heavily or rapidly will wear out their gas cartridges faster.

Storage conditions of the gas cartridge:

The storage conditions of the gas cartridges will also affect their life expectancy. Unopened gas cartridges should be stored in a dry, ventilated environment, out of direct sunlight, and in accordance with the manufacturer's recommended storage period. Opened gas cartridges should be properly sealed and used as soon as possible to avoid performance degradation.

In summary, the factors affecting the service life of the gas cartridges are manifold, including the concentration of toxic and hazardous substances, the mixing of hazardous substances, the ambient humidity, the ambient temperature, the duration of use, the respiratory frequency and intensity of the user, and the storage conditions of the gas cartridges. Therefore, when using gas cartridges, it is necessary to take these factors into account and develop a corresponding replacement programme to ensure protection.
