Key Benefits of R+F Spunbond Filter Media
1. High mechanical strength
Spunbond technology creates a three-dimensional fiber network with outstanding tear and tensile strength. This makes R+F Spunbond media particularly suitable for applications with:
- High flow rates
- Mechanical stress (e.g. tension in filter belts)
- Frequent handling during installation or cleaning
2. Stable filtration performance
The uniform fiber distribution ensures a consistent pore structure over the entire web. This leads to:
- Predictable filtration performance
- Uniform particle retention
- Reduced risk of channeling and bypass flow
3. Chemical resistance and temperature stability
Depending on the selected polymer (polyester or polypropylene), R+F Spunbond media offer:
- Good resistance to oils, coolants and many process liquids
- Dimensional stability at typical industrial operating temperatures
- Suitability as a carrier layer in multi-layer filter designs
4. Ideal as primary or support layer
R+F Spunbond Series can be used:
- As a standalone coarse filter for chips, fines and larger particles
- As a pre-filter upstream of finer meltblown or microfiber layers
- As a support and protection layer for delicate fine media in composite constructions
Typical Applications
R+F Spunbond media are used in a wide range of industrial filtration tasks, including:
- Coolant and lubricant filtration in metalworking processes
- Gravity and vacuum filter systems for machining operations
- Pre-filtration in liquid treatment systems
- Carrier and drainage layers in multi-layer filter cartridges and pads
- Industrial air pre-filtration where a robust, washable medium is required
If you are working on a new filter design or upgrading an existing system, our team will support you in selecting the right Spunbond grade for your process.
Available Polymer Types and Formats
Polymer options
Polyester (PES):
For applications requiring higher temperature stability and good resistance to many oils and solvents.Polypropylene (PP):
For applications in aqueous systems and where excellent chemical resistance at moderate temperatures is required.
Supply forms
- Standard roll goods in defined widths and lengths
- Custom roll widths, tailored to your production equipment
- Optionally converted formats in cooperation with our European partners (sheets, pads or other geometries on request)
Support in Media Selection and Converting
Choosing the right filter media is critical for the performance and reliability of your system. We support you with:
- Media selection based on process parameters (flow rate, temperature, medium, particle load)
- Recommendations for layer combinations, e.g. Spunbond + Meltblown
- Advice on roll widths and formats for efficient processing in your production
If required, we work with experienced converting partners in Europe to supply slit rolls or cut pieces according to your specifications.
For OEM projects, retrofits or trials, we will gladly provide:
- Material samples of selected R+F Spunbond grades
- Basic data sheets with key technical parameters
- Support in evaluating the media performance in your application
