PTFE Filter (Polytetrafluoroethylene Filter) has many advantages, it is popular in cleanroom applications when the manufacturing environments need tight control, such as in the semiconductor industry. These advantages help maintain a high cleanliness level manufacturing process environment.

1. High Filtration Efficiency

PTFE filter has an extremely fine pore structure and the filtration efficiency can be 99.99% to 99.999995%. It can effectively filter small particles such as dust, particles, and aerosols from 0.1µm to 0.3µm. It is suitable for environments with extremely high requirements for air cleanliness. Ensure the air quality meets the high standards of semiconductor manufacturing processes.

2. Low Pressure Drop and High Airflow Rate

Because of the optimized structures, PTFE filter is smooth and has good air permeability. Low pressure drop means the resistance is low when the air goes through, it not only improves the efficiency of the air filtration but also reduces the energy consumption of the HVAC system and achieves the energy-saving effect. PTFE filter can help stabilize the airflow, low pressure also extends the service life of the filter.

3. Low Outgassing

PTFE filter does not contain boron, potassium, silicon, or other substances that will vaporize in humid or acidic environments, so the PTFE filter does not release molecules, this avoids the risk of contamination in highly sensitive cleanroom in semiconductors, optoelectronics, and medical industries.

4. Excellent Chemical Resistant

PTFE has high chemical erosion-resistant performance, it can resist chemical substances such as acids, alkalis, and organic solvents. This feature makes PTFE stable with various chemical and volatile substances in the environment. Especially when dealing with strong acids (such as hydrofluoric acid, sulfuric acid, hydrochloric acid, etc.), PTFE filters can maintain stability without being corroded and are widely used in chemical processing, semiconductor manufacturing, optoelectronics, pharmaceuticals, and other industries. Its chemical resistance not only effectively prevents damage to the filter from chemical substances, but also ensures that the purity of the sample is not contaminated during the filtration process, thereby providing the accuracy of subsequent analysis.

5. Long-term Stability and Durability

PTFE filter is highly durable, it can maintain stable performance in a harsh environment for a long time, reducing the filter replacement frequency and maintenance costs, this can help improve production efficiency. PTFE filter is strong and does not generate particles when pleated or used, therefore, it does not contaminate the environment.

6. Hydrophobic and Anti-adhesive

The surface of PTFE is hydrophobic and anti-adhesive by nature, this can prevent moisture and particles from attaching to the filter surface. PTFE can also maintain stable filtration efficiency in humid environments. It is more stable and reliable than filter media uses electrostatic to capture particles. PTFE filter can reduce the risk of contamination while maintaining the filtration performance.
