Shenzhen DouFang Technology Co.,Ltd products

It can be widely used in various high-end air filtration fields such as industrial-grade dust-free clean rooms, and can also be applied to some civilian-grade requirements. It has a good and obvious filtering effect on PM2.5, PM10 and other particulate matter. According to the different requirements of domestic and foreign customers, the products can be designed, produced and supplied completely in accordance with domestic industry standards or international standards, and comply with international general requirements such as EN779/ISO16890.

This product is made of 30% polypropylene fiber (PP) and 70% polyester fiber (PET). It reduces the filtering resistance and increases the dust holding capacity. It has the characteristics of low resistance, high efficiency, high strength, and environmental protection. It is widely used in the field of air purification.

The bag filter material is made of polyester fiber non-woven fabric, melt-blown non-woven fabric and other materials by ultrasonic welding. The air supply is more uniform, the resistance is smaller, the service life is longer, and the made filter is more beautiful and practical.
