2. FFU can be divided into primary filter, high efficiency filter and sub-high efficiency according to its working principle.
3. Suitable for air filtration at room temperature and humidity, allowing organic solvents containing trace acids and alkalis. This product has high efficiency, low resistance and large dust holding capacity. It is widely used in aerospace, aviation, electronics, pharmaceuticals, bioengineering and other fields.
