The Importance of Polyester Fiber Filter Media in Dust Control

The Importance of Polyester Fiber Filter Media in Dust Control

As we all know, the air contains a large amount of dust particles (such as dust, soot, mineral dust, sand, powder, etc.). Because these dust particles are very light, when moving air acts on them, it counters their weight, causing them to float. Dust particles will only settle under the influence of Earth's gravity in relatively enclosed spaces where the air is relatively still. This is why in rooms with tightly closed doors and windows, after a period of time without human occupancy, a thick layer of dust can be found on furniture and the floor. The amount of dust in the air is influenced by many objective factors such as weather, seasonal changes, industrial production, mineral extraction, land desertification, soil erosion, environmental pollution, and more. Dust has impacts on human health, production, product quality, the environment, the aesthetic value of natural scenery, and ecological balance.

An adult needs approximately 19m³ of air each day to obtain the oxygen required for their body. If the air in a worker's environment contains a large amount of dust, the amount of dust that enters their lungs increases. Many harmful gases, liquids, or certain metal elements can attach to the dust particles and be carried deep into the lungs or adhere to the walls of the bronchi as the worker breathes. This can cause or exacerbate respiratory diseases. When dust accumulation reaches a certain level, it can lead to fibrosis of lung tissue, causing the tissue to harden, losing its normal respiratory function, and triggering related diseases. This is why wearing a mask in environments with poor air quality can effectively prevent disease. A mask is essentially a form of Polyester Fiber Filter Media, which can efficiently filter out dust particles from the air, ensuring the air that is inhaled is clean.

When dust settles on the rotating parts of machines, it accelerates wear and tear, reducing the machine's precision and lifespan. Dust floating in workshops also reduces visibility, affects the field of vision, hinders operations, lowers labor productivity, and can even lead to accidents. Dust emissions into the atmosphere contribute to air pollution, and in addition, airborne dust reduces visibility, promotes the formation of smog, and interferes with the transmission of solar radiation.

In conclusion, Polyester Fiber Filter Media plays an indispensable role. Many industrial processes must take place in relatively clean spaces, such as surface treatment, painting, spraying, precision electronics, optical electronics, biopharmaceuticals, food production, and air cooling. These environments require airflow but must be free of dust. Therefore, Polyester Fiber Filter Media is needed to remove the dust, allowing only clean air to circulate in relatively enclosed spaces, thus meeting the needs of production operations.
