Providing a Full Range of F6–F9 Medium Efficiency Glass Fiber Filter Paper

PLM Filter medium efficiency glass fiber is specifically designed for reliability and long service life under harsh operating conditions such as high speed and turbulence. The medium efficiency glass fiber media is not affected by airflow changes or repeated fan shutdowns. It has a large filtration area, high dust holding capacity, large airflow, low resistance, and long service life. It is suitable for environments below 150 °C and has good flame retardant properties, making it a common configuration for ventilation and air conditioning systems. It is suitable for bag filters, non-partition filters, partition filters, and combination filters.

PLM Filter has extensive market experience and expertise, with a high-quality supply chain system. We are a trusted raw material supplier for many air filter manufacturers. We are committed to providing support and assistance for your business.

Professional Advice

In the medium efficiency glass fiber filter paper field, different operating environments lead to varying requirements for medium efficiency glass fiber filter paper. We have extensive experience and expertise in this field, and we will recommend the best product type based on your specific operating requirements and environment, providing full-process technical support.

First, the filtration grades of medium efficiency glass fiber filter paper are divided into F5, F6, F7, F8, and F9. The higher the grade, the higher the filtration efficiency. We will recommend corresponding product grade based on your usage environment and requirements.
Secondly, different filters perform differently at various air speeds. The recommended airspeed for general medium efficiency filters is around 2.5 m/s, but it should be adjusted according to actual needs. We will recommend an appropriate glass fiber filter paper based on the filter's airspeed environment.
Additionally, for ordinary industrial environments, we recommend choosing lower-grade medium efficiency glass fiber filter paper; For places with higher air cleanliness requirements, such as electronics factories and pharmaceutical production workshops, it is recommended to choose high-efficiency medium glass fiber filter paper.

We are committed to providing you with the most professional service and the highest quality products. We look forward to cooperating with you. If you have any questions or needs, please feel free to contact us.
