Air Guard’s Practical Application Solutions and Advantages——Case Analysis of Dongguan Metro Line 2:

Case Background
With the rapid development of urban transportation systems, metro, as an important public transport, sees the air quality in carriages directly affect passengers’ health and comfort. To address this challenge, Air Guard Purification Technology Group provided a customized air purification solution for Dongguan Metro Line 2.

Solutions and Implementation

Air Guard’s air filtration and purification product units adopt the most advanced filtration technologies and innovative design schemes. These technologies include nano-level high-efficiency filters, which can effectively capture and intercept harmful substances in the air, such as particulates and bacteria. Combined with high-performance negative ion generator units and working together with the air conditioning fresh air circulation system, they achieve efficient purification of the turbid air in carriages.

In particular, Air Guard’s specially designed air conditioning filters for rail transit can not only efficiently filter harmful substances such as particulates, formaldehyde, and VOCs (volatile organic compounds) in metro carriages, but also intercept metal dust and iron particles entering the carriages, and inhibit the growth of microorganisms such as bacteria and viruses. This comprehensive protection measure significantly reduces the risk of pathogen transmission through aerosols in crowded crowds.

In addition, Air Guard’s technical team also highlights the energy-saving features of its products. By optimizing filter materials, improving product structure, and reducing air resistance, Air Guard’s products not only ensure high-efficiency filtration but also significantly reduce energy consumption and carbon emissions. For example, the surface of the innovative filter material is treated with hydrophobicity, which helps prevent the formation of water films due to the humid underground environment during high-speed train operation, maintains sufficient ventilation performance, and thus reduces air conditioning energy consumption and operational maintenance costs.
