High Performance Air Filter Media​

PTFE Filter Media​

HG PTFE filter media features a microporous expanded PTFE membrane that delivers ultra-low resistance, superior hydrophobicity, and outstanding chemical resistance. Designed for high-efficiency and ultra-high-efficiency filtration , it ensures consistent performance and extended service life in cleanrooms, semiconductor fabs, and pharmaceutical production environments.

Synthetic Fiber Filter Cotton

The synthetic fiber filter cotton takes polyester fiber as the main raw material and has the characteristics of being economical and practical, having a low initial resistance, a high dust-holding capacity, being safe and environmentally friendly, being easy to use, and having good dimensional stability. This series of products is mainly used for filtration and is the most commonly used filter material in air purification filtration, mainly filtering particulate dust and suspended matter with a particle size of ≥ 5 μm in the atmosphere.

Meltblown Filter Media

Meltblown Filter Media HG meltblown filter media features a fine fiber structure that enables superior particle capture, providing high filtration efficiency and low pressure drop in advanced air filtration systems.

Nanofiber Filter Media

Nanofiber filter media are advanced filtration materials made using nanotechnology, typically through electrospinning. These ultra-fine fibers, usually with diameters below 500 nanometers, form a web-like structure that significantly enhances particle capture efficiency.
