“Recognizing the unique demands of Lithium-Ion Battery (LiB) and Lithium Iron Phosphate (LFP) production, Freudenberg has developed NMP (N-Methyl-2-Pyrrolidone) compatible filter media resistant to aggressive organic solvents.”
Freudenberg Filtration Technologies has announced the expansion of its advanced product portfolio to include next-generation Fan Filter Units (FFUs), BIBO (Bag-In/Bag-Out) systems with integrated blowers, and specialized NMP-compatible filters engineered for the demanding environments of Lithium-Ion Battery (LiB) and Lithium Iron Phosphate (LFP) production.
Innovation in Cleanroom Air Filtration
The new Freudenberg FFU Series is designed for semiconductor, battery, and pharmaceutical cleanrooms, offering precise control of laminar airflow with HEPA and ULPA filtration efficiency up to ISO Class (per ISO 14644-1).
Key advantages include:
- Energy-efficient EC motor design, reducing power consumption by up to 35%.
- Smart controlling options for larger clusters with CCM software.
- Uniform airflow distribution, ensuring critical process stability.
- Low vibration and acoustic performance, ideal for sensitive production zones.
- Smart monitoring options for differential pressure and filter life tracking.
Enhanced Safety with BIBO Systems
For hazardous material handling environments, Freudenberg has introduced the BIBO with integrated blower module, designed to meet containment standards. These systems ensure safe replacement of filters without operator exposure, making them ideal for toxic exhaust streams.
Key features include:
- Modular stainless-steel housing for flexible installation.
- Gas-tight sealing and pressure-tested containment.
- Integrated EC blower for stable airflow during filter changeover.
- Compatibility with HEPA/ULPA, activated carbon, and specialty chemical filters.
Specialized Filtration for NMP and Battery Manufacturing
Recognizing the unique demands of Lithium-Ion Battery (LiB) and Lithium Iron Phosphate (LFP) production, Freudenberg has developed NMP (N-Methyl-2-Pyrrolidone) compatible filter media resistant to aggressive organic solvents.
Applications include:
- Dry rooms and coating lines in electrode manufacturing.
- Exhaust filtration for solvent recovery and air purification.
- VOC and acid gas removal using hybrid chemical filters.
