Structure: The coated polyester filter cartridge uses polyester filter material as the base material, and a special film is coated on its surface. This film is usually made of high-performance materials such as polytetrafluoroethylene (PTFE) and has excellent chemical stability and physical properties.

Material: The polyester filter material itself has good mechanical strength and wear resistance, while the PTFE coating gives the filter cartridge higher filtration accuracy and longer service life. In addition, some products are also made of imported composite long-fiber spunbond polyester non-woven fabrics, which further improves the filtration effect.

High-efficiency filtration: The coated polyester filter cartridge has a very high capture efficiency for ultra-fine and special dust, and the dust removal efficiency for ultra-fine dust above 0.3μm can usually reach >99.8%. This is due to its smooth PTFE coating, which can effectively intercept and adsorb tiny dust particles.

Low resistance loss: Due to the excellent air permeability of the PTFE coating, the filter cartridge has a small resistance loss during the filtration process and can maintain a stable filtration efficiency for a long time.

Long life: The coated polyester filter cartridge is made of a special process, with a smooth surface and not easy to wear, and can resist the tearing and scratching of powder particles. At the same time, its easy cleaning characteristics also extend the service life of the filter cartridge.

Corrosion resistance and high temperature resistance: The PTFE coating has stable chemical corrosion resistance and can resist the erosion of corrosive substances such as acids and alkalis. In addition, the polyester filter material itself has high temperature resistance, which enables the filter cartridge to be used in a wide temperature range.

Easy installation and maintenance: The coated polyester filter cartridge usually adopts a modular design, which is convenient and quick to install and replace. At the same time, its easy cleaning characteristics also reduce maintenance costs and time.

The coated polyester filter cartridge is widely used in welding smoke, shot blasting casting, pharmaceuticals, cement, tobacco, textile industry and other fields. In these fields, coated polyester filter cartridges can effectively purify the air, protect the environment and improve production efficiency.
