Thanks to our spunlace technology, we can offer a range of self-pleatable filter media as alternative to conventional spunbond filter media in form of filter cartridges and pleated filtermedia.

Regular Temperature Applications:
For applications with operating temperatures below 130 degrees C, we make use of fibers such as PET, PAN, PA, etc.
To achieve media pleatability, binders could be applied or bi-compinent fibers (Bico) included in the fabric.

High Temperature Ranges:
We process fibers such as PPS, Meta Aramids, Polyimide, PTFE etc. to create filtermedias used in temperature ranges above 150 degrees, up to 260 degrees C. Thanks to our innovative technology, Norafin can offer binder-free/resin-free medias by incorporating a steel scrim/wire mesh in the core of the filtermedia. This unique technology provides an enhanced pleat stability and performance reliability even under tremendous temperature operation.

End Uses:

  • metal and wood processing; powder processing in general
  • mineral industry
  • food industry

Performance Characteristics of our Products:

  • optimized filtration efficiency and flow rates
  • high efficiency of spunlaced nonwovens at low weights in comparison to spunbond nonwovens (weight range between 180 g/m² and 350 g/m²)
  • 200 g/m² as more efficient alternative to 260 g/m² spunbond nonwoven
  • filtration efficiency from F7 - F9 according to EN 779, class L, M according to IFA/BGIA DIN EN 60335-2-69
  • high durability through high mechanical resistance, stiffness and pleatability
  • energy-efficient due to low increase of differential pressure and high air permeability
  • stiffening with or without binder as well as through pleatable support scrims
  • unique, nonresinous, pleatable, temperature resistant filter media
  • flow rates from 50 up to 3000 l/dm²/min
  • antistatic

Our possible product modifications

Since our fabrics can be individually engineered to improve cleaning characteristics, mechanical stability and dust holding capacity, we can always match specific client needs regarding product attributes and efficiency.

Be it in process air or dust filtration, HVAC or process liquid filtration, it is our aim to transform your need into the right product concept and offer a durable solution that supports a safer life.

Fibers & Fiber blends

Processing of different fibers and fiber blends:

  • temperatures below 130 °C: Bi-Component fibers (Bico), PET, PAN, PA, PP, viscose
  • temperatures over 150 °C: PPS, aramids, PI, PTFE, Ox-PAN

for covering a wide range of temperature and chemical resistance.

 

Process Technology & Area Density
  • spunlaced filter media (30-500 g/m²) for ideal filtration efficiency vs. flow rates:
    • provides more surface and fine filtration
    • very dense structures
  • needlepunched filter media (30-900 g/m²) for ideal dust holding capacity
    • provides more depth filtration
    • voluminous structures
  • hybrid structures, that combine spunlaced and needlepunched nonwovens; multi-layer constructions

 

Multilayer Options
  • with or without support structure
  • TOP Layer-Technology: surface oriented filtration layer / membrane-like effect layer
  • multi-layer-technology: integration of metallic layers possible
Customized Cutting and Packing

We can supply our customers with roll widths from 100 mm min. up to 2300 mm max.

Aftertreatment
  • impregnating:
    • water- and oil repellency
    • flame-retardant
    • reinforcement/stiffening
  • calendering:
    • surface modifications
  • foam application:
    • stable/unstable
  • lamination

 

Since our fabrics can be individually engineered to improve cleaning characteristics, mechanical stability and dust holding capacity, we can always match specific client needs regarding product attributes and efficiency.

Norafin ECOLINE®

The use of renewable raw materials is important to us in terms of sustainability of our production chain.

In the sense of the Circular Economy and only, where permitted by the final application, we can provide the use of recycled fibers to our customers.

In our Filtration Line, the use of recycled PET plays an important role. Thanks to our in-house technology we are also able to recover high-performance fibers such as aramids.
