Product feature

High efficiency filter media

  • Higher filtration accuracy: Finer than traditional filtration media, effectively filter smaller particles and bacteria and other microorganisms.

  • Lower resistance: Nanofiber three-dimensional structure, large specific surface area, smaller aperture, reduces the resistance of air flow, while ensuring the purification effect of indoor air.

  • Longer service life: Nano-fibre filter has small fibre spacing, stable structure, high tensile strength of the filter material, not easy to be damaged and worn out. At the same time, the resistance of nano-fibre filter rises slowly, the nano-fibre filter takes longer to reach the same final resistance, which reduces the number of times of replacement and maintenance, and has a longer service life.

  • Improve clean room production efficiency: Some production processes in clean rooms need to be carried out under specific temperature and humidity conditions, such as semiconductor processing, coating treatment, etc. If the temperature or humidity is unstable, it will affect the production efficiency and process accuracy, which will lead to product performance and quality problems. Maintaining the stable temperature and humidity in the clean room can reduce the change of water content in the product and improve the stability and reliability of the product. The low-resistance nanofiber filter can increase the air flow speed and help maintain a stable temperature and humidity in the clean room, thereby improving the production efficiency and product quality of the clean room.

  • Smaller system noise: At the same wind speed, the high efficiency and low resistance nanofiber filter requires less air and less noise, reducing the noise damage to the staff.

  • Reduce energy consumption and production costs: Nanofiber filter has lower resistance, the required air volume is smaller, and the low-resistance filter can reduce the working load of the fan, reduce noise and energy consumption, and reduce energy costs; At the same time, due to its longer life, the number of replacement and maintenance can be reduced, which also reduces the cost of replacing the filter; Ensure production efficiency and product quality, reduce the production cost of enterprises.
