Stainless steel centrifugal fans play a crucial role in indoor air purification and ventilation, particularly in enclosed spaces. Their main function is to increase gas pressure, ensuring efficient air distribution and circulation, which helps maintain airflow and purify indoor air. The challenges of indoor air purification stem from the following factors:

1. Emission and Accumulation of Harmful Substances

• Indoor air quality is affected by various factors, especially chemical products, building materials, and furniture used in daily life and work. These can release harmful substances such as formaldehyde, benzene, ammonia, and radon. These substances accumulate in enclosed spaces and pose long-term health risks, especially affecting the respiratory and immune systems.
  • Formaldehyde, for example, is a common volatile organic compound (VOC), and prolonged exposure can lead to respiratory irritation and even cancer.
  • Radon is a naturally occurring radioactive gas that, with long-term exposure, can cause serious health issues, such as lung cancer.

2. Insufficient Indoor Ventilation and Purification

• With the increasing airtightness of modern buildings, many have reduced ventilation capacity. The circulation of air in enclosed spaces becomes obstructed, leading to the inability to expel pollutants in a timely manner. In some cases, the concentration of harmful substances in the air can exceed that of the external environment.
  • Industrial Environments: Some workshops and factories generate a large amount of harmful gases due to their production processes or the materials used. Without proper ventilation equipment, this can lead to severe air pollution and negatively impact employees’ health.

3. Role of Centrifugal Fans

• Airflow and Ventilation: Stainless steel centrifugal fans increase gas flow and pressure, ensuring effective circulation of air. By drawing fresh outdoor air through the intake and expelling polluted indoor air through the exhaust, they maintain indoor air movement and effectively reduce the concentration of harmful substances, improving air quality.
• Filtration and Purification: Many stainless steel centrifugal fans are equipped with high-efficiency filters that effectively remove dust, pollen, bacteria, and other particulates from the air. Additionally, some fans have functions like dehumidification and deodorization, helping to further purify the air and reduce the impact of harmful substances on human health.

4. Necessity of Indoor Atmosphere Purification

• With the development of modern industry and architecture, the demand for indoor air purification is increasing, especially in confined spaces. In such environments, the lack of effective air circulation leads to the accumulation of pollutants, which degrades environmental quality and poses health risks.
  • In special working environments (e.g., chemical plants, laboratories), air quality is crucial for employee health, making equipment like stainless steel centrifugal fans indispensable.

5. Technological Measures to Address Pollution

• Air Purification Systems: In high-pollution work environments, air purification systems such as high-efficiency particulate air (HEPA) filters, activated carbon adsorbers, and ultraviolet (UV) air disinfection devices can be added to effectively remove harmful substances from the air.
• Regular Maintenance: Regular inspection and maintenance of fans and purification equipment are essential. Ensuring that filters are not clogged and that the fan operates normally is critical for maintaining an efficient ventilation system.

Conclusion:

Stainless steel centrifugal fans play an important role not only in industrial production for ventilation and gas transport but also in improving indoor air quality and protecting human health. Especially in enclosed spaces, ensuring proper air circulation and purification is vital to prevent the accumulation of harmful substances and safeguard the safety of work and living environments.
