What is the service life of vents?

The service life of vents is generally around 10-25 years, but the specific service life will be affected by many factors.
If the vents are made of high-quality materials, the construction is standardized and the subsequent maintenance is proper, and the environment is relatively mild without extreme temperature, humidity and chemical corrosion, its service life may reach more than 20 years.
However, if the material quality is average, there are defects in the construction, such as loose splicing, loose fixing, or the use environment is harsh, such as long-term exposure to strong ultraviolet rays, strong acids and alkalis, its service life may be only 10 years or even shorter.
