Air filtration is an important field in filtration technology and is widely used in many industries and scenarios. Its purpose is to remove fly ash from ambient air, various air inlets, vehicle exhaust, power plant flue gas, and dust particles from incinerator flue gas. Among many filter materials, ePTFE (expanded polytetrafluoroethylene) membrane has become a leader in the field of air filtration due to its unique performance and high efficiency.

Comparison of pressure difference between ePTFE filter and traditional filter

ePTFE membrane has excellent chemical stability, temperature resistance, low differential pressure and high filtration efficiency. Its microporous structure is very unique, with millions of micropores per square centimeter, and the pore size range is usually between 0.05-0.2μm, which can effectively intercept submicron particles.

The surface filtration mechanism of this material prevents dust particles from entering the filter medium when intercepting them, thus avoiding the common clogging problem of traditional filter media, maintaining a stable pressure difference, and extending the service life of the filter.

The surface filtration technology of the ePTFE membrane enables it to maintain a low pressure drop when intercepting particles, which means that during the air filtration process, the system requires less energy, thereby achieving energy saving. In addition, since the ePTFE membrane does not need to rely on filter cakes to improve filtration efficiency, the filter can be cleaned more effectively, further extending the service life of the filter and reducing maintenance costs.

The application of ePTFE membrane in air filtration has demonstrated its excellent performance and broad application prospects. It provides a reliable solution for various air filtration needs through its advantages such as efficient particle interception ability, low pressure drop and long life, and is an indispensable and important material in modern filtration technology.
