How many layers does the wet curtain filtration system of the 80W20L portable air cooler have?

The wet curtain filtration system of the 80W20L portable air cooler is one of the core components of its efficient cooling and air purification functions. The system is specially designed as a three-layer structure, with each layer undertaking different functions and working together to achieve the best results. Cooling and purifying effects.
First of all, the first layer of wet curtain mainly plays the role of preliminary filtration. It can capture larger particles in the air, such as dust, hair, etc., effectively prevent these impurities from entering the inside of the machine, and protect the subsequent filter layer and the entire cooling system from contamination. This layer of wet curtain usually uses rougher fiber materials to increase the surface area and improve capture efficiency.
The second layer of wet curtain is more refined and designed to further filter tiny particles and bacteria in the air. The fibers of this layer of wet curtain are finer and can capture smaller diameter particles in the air. At the same time, the wet fiber surface can also absorb some harmful gases and odors in the air, providing preliminary purification of the air.
The third layer of wet curtain is the layer with the most significant cooling effect. It not only continues to undertake the task of filtration, but more importantly, through its special fiber structure and moist state, it uses the principle of water evaporation and heat absorption to greatly reduce the temperature of the air passing through the wet curtain. When hot air passes through moist fibers, the water evaporates and absorbs a large amount of heat, causing the air temperature to drop rapidly, giving users a cool and comfortable feeling.
In addition, the wet curtain filtration system of the 80W20L portable air cooler also combines environmentally friendly dust removal filtration and water circulation physical humic acid purification technology. The environmentally friendly dust removal filter layer can more effectively remove fine particles in the air, while the water circulation physical humic acid purification can decompose organic matter in the water during the circulation process, inhibit bacterial growth, and keep the water clean, thereby ensuring that the blown air is fresher and healthier .
