Process Liquid Filtration

Requirements for the filtering of process liquids varies depending on their field of application. From pebbles to grains of sand to microscopic particles, it is important to adapt the attributes of the filter media to its application.

End Uses:

  • gravity filters
  • flat bed filters for cooling and lubricant solvents in metal processing
  • plate filters
  • deep bed filters
  • hydrostatic filters
  • depression filters

Performance Characteristics of Our Products:

  • possible to adjust density to achieve best flow rates and optimal efficiency rates
  • high particle intake capacity
  • filtration efficiency (separation efficiency from 100 up to 10 µm)
  • high durability, stability and reliability during handling and operation

Possible Product Modifications:

  • adaption of product features (for covering a large spectrum of temperature and chemical resistance) through the processing of various different fibers, such as PP, PET, CoPET, viscose, PA 6, PA6.6
  • adapted flow rates from 50 up to 3000 l/dm²/min
  • spunlaced filter media for optimized filtration efficiency vs. flow rates
    • provides more surface and fine filtration
    • very dense structures
  • needlepunched filter media for optimized filtration efficiency vs. flow rates
    • provides more depth filtration
    • voluminous structures

Automotive-/Aircraft Liquid Filtration

Norafin offers a wide range of specialized structures and materials for filter media and develops tailor-made solutions for automotive and aircraft liquids, including diesel/gasoline and oils.

Different Fiber Entangling Technologies

  • spunlaced filter media for optimized filtration efficiency vs. flow rates
    • provides more surface and fine filtration
    • very dense structures
  • needlepunched filter media for optimized filtration efficiency vs. flow rates
    • provides more depth filtration
    • voluminous structures
  • hybrid structures, which combine spunlaced and needlepunched nonwovens; multi-layer contruction

Based on these possibilities, Norafin offers structures for filter media with an optimized ratio of dust holding capacity, filtration efficiency, pressure drop, life time and cost, measured according to ISO 16889 und ISO 19438.

Possible Product Modifications:

  • different fiber choices compatible with automotive and aircraft liquids: polyester, polyamide 6, aramids
  • dewatering solutions based on:
    • water super absorbent fibers with water absorbing weight to weight capacity up to 1600 %
    • coalescing and drainage filter media options
