🔬 Freudenberg Expands: Advanced Filtration for Cleanrooms and LiB Battery Manufacturing.

Freudenberg Filtration Technologies has expanded its product portfolio with advanced filtration solutions designed to meet the rigorous demands of cleanroom and battery manufacturing applications, focusing on efficiency, safety and specialized chemical resistance.

The new offerings address critical needs in semiconductor fabrication, pharmaceutical production, and the rapidly growing lithium-ion (LiB) and lithium iron phosphate (LFP) battery sectors.


🌬️ Core Filtration Solutions

Freudenberg’s expanded portfolio is anchored by three major product lines:

1. Fan Filter Unit (FFU) Series

This new series is engineered for high-precision cleanroom environments, such as those found in semiconductor, battery, and pharmaceutical manufacturing.

  • Function: Delivers precise laminar airflow control.
  • Efficiency: Utilizes HEPA and ULPA filtration media, compliant with ISO 14644-1 cleanroom standards.
  • Energy Savings: Features an EC motor (electronically commutated motor) technology, which reduces power consumption by up to 35% compared to conventional AC systems.
  • Smart Features: Includes integrated smart monitoring for differential pressure and filter life, with central control options (CCM software) for managing large clusters of units.
  • Stability: Designed for sensitive production areas with characteristics like uniform airflow distribution and low vibration.

2. BIBO Systems with Integrated Blowers

The Bag-In/Bag-Out (BIBO) systems are specialized for containment applications involving hazardous or toxic materials, ensuring operator safety during filter maintenance.

  • Safety: The system enables safe filter replacement without exposing the operator to the toxic exhaust or contaminated filter media.
  • Integrated Design: Features an integrated EC blower module, which maintains stable airflow even during the filter changeover procedure.
  • Construction: The housing is made of modular stainless steel for flexible installation and incorporates gas-tight sealing and pressure-tested containment to meet stringent safety compliance standards.
  • Compatibility: Accommodates various filter types, including HEPA, ULPA, activated carbon, and specialty chemical filters.

3. NMP-Compatible Filtration for Battery Production

This solution is specifically developed to overcome the challenging filtration requirements of lithium-ion and lithium iron phosphate (LFP) battery manufacturing.

  • Chemical Resistance: The filter media is resistant to N-Methyl-2-Pyrrolidone (NMP) and other aggressive organic solvents used during the electrode coating process.
  • Process Integrity: The filters are built to maintain their mechanical integrity, particle retention, and airflow stability even when exposed to high humidity and concentrated solvent vapors.
  • Key Applications: Includes filtration for:
    • Dry Rooms and Coating Lines
    • Exhaust filtration for solvent recovery
    • VOC (Volatile Organic Compound) and acid gas removal using hybrid chemical filters.

🌍 Strategic and Global Context

This product expansion directly addresses two major global trends: the increasing precision requirements of advanced manufacturing (like semiconductors) and the rapid, global growth of battery production capacity (Gigafactories). By focusing on energy efficiency (EC motors) and operator safety (BIBO systems), Freudenberg is positioning its new solutions to support both the performance and sustainability objectives of its industrial clients worldwide.

Freudenberg Filtration Technologies is part of the broader Freudenberg Group, which has a long-standing operational history in India spanning over 90 years.
