Synthetic Fiber Pocket Filter F9 is a quasi-high-efficiency air filtration device that complies with EN 1822 and ISO 16890 ePM1 90%-95% standards. Its filtration performance is close to HEPA H13 level. It is designed to intercept 0.1-5μm ultrafine particles (such as viruses, bacteria, smoke, aerosols and nano-scale industrial dust). It uses cutting-edge composite fiber technology and reinforced structure, becoming the core purification component of ultra-sensitive scenarios such as biopharmaceuticals, semiconductor manufacturing, and high-grade clean rooms, providing top protection for process sterilization and personnel health.

Selection and maintenance guide

Accurate selection suggestions

Air volume matching:

Calculate the number of filter bags based on the system air volume (such as 36-40 bags for 30,000m³/h), and the wind speed is recommended to be ≤1.5m/s;

Select nano-hydrophobic coating + stainless steel frame for high humidity scenes.

Pollution characteristics:

Biological hazards: select antibacterial + antiviral composite filter material;

Corrosive gas: PPS frame + chemical resistant coating.

Intelligent maintenance strategy

Pressure difference monitoring: intelligent pressure difference sensor linked to BMS system, replacement threshold is initial pressure difference × 2.5 (usually ≤325Pa);

Cleaning restrictions: any cleaning is prohibited, only surface dust collection is supported (risk of irreversible damage to microfiber structure);

Replacement cycle:

Conventional clean workshop: 18-24 months;

High pollution industrial scene: 9-12 months.

Technological innovation and industry trends

Nanotechnology integration: graphene conductive layer monitors particle load in real time, AI algorithm dynamically optimizes filtration efficiency;

Zero carbon design: bio-based polyester fiber (30% plant source) is used, carbon footprint is reduced by 40%, supporting Net Zero goal;

Modular quick change: magnetic filter bag design, no tools are required to achieve replacement within 5 minutes, reducing downtime losses.
