SPUNBOND POINTBOND POLYESTER
Premium polyester filter media for multi-application filtration.
Excellent for oil-heavy environments with superior strength and consistent particle entrapment.
Pressure, Vacuum & Gravity Compatible
FDA Food Grade Approved
0.6 - 1.5 OSY Weight Range
Superior Oil Resistance
WHY CHOOSE SPUNBOND POINTBOND POLYESTER?
Superior Oil Resistance
Excels in straight oil applications where other media fail. Maintains structural integrity and filtration efficiency even in oil-saturated environments.
Exceptional Strength
High tensile strength in both cross and machine directions reduces tearing and downtime, especially critical in high-pressure filtration systems.
Uniform Filtration
Even fiber distribution provides consistent particle entrapment across the entire surface, eliminating weak spots and premature failures.
Versatile Weight Options
Four basis weights (0.6-1.5 OSY) allow you to optimize for different filtration requirements and service life needs.
FDA Compliant
Meets FDA regulations for food-grade applications, opening opportunities in food and beverage processing industries.
Tight Filtration Capability
Suitable for applications requiring fine particle capture while maintaining good flow rates and extended service life.
Advantage Over Flatbond Polyester:
Unlike flatbond polyester, our spunbond pointbond construction delivers more uniform fiber distribution, which means more consistent filtration performance and better particle capture across the entire filter surface. No weak spots, no premature clogging.

Is This the Right Filter Paper for You?
Best Suited For:
- Operations with heavy oil presence or straight oil coolants
- Applications requiring consistent, tight filtration
- High-volume grinding operations
- FDA-regulated food/beverage processing
- Situations where filter strength and durability are critical
- Multi-shift operations requiring extended filter life
Consider Alternatives If:
- You need extremely fine micron filtration (see finer-grade options)

- You're running high-temperature processes (high-temp media)
- Budget is the primary concern (economy options)
How Spunbond Pointbond Polyester Works
The Science Behind the Performance
Our spunbond pointbond construction creates a three-dimensional fiber matrix that traps particles throughout the depth of the media, not just on the surface. The pointbond process thermally bonds fibers at their intersection points, creating a strong yet porous structure.
1
Structural Integrity
Maintains strength under pressure without tearing or delaminating, even in demanding applications.
2
Even Distribution
Distributes particles evenly, preventing premature clogging in weak spots common with other media.
3
Oil Handling
Handles oil-laden fluids without breaking down or losing filtration efficiency.
4
Extended Life
Delivers consistent flow rates and loading capacity throughout the entire service life.

Frequently Asked Questions
What's the difference between spunbond pointbond and flatbond polyester?
The key difference is fiber distribution. Spunbond pointbond offers more uniform fiber placement throughout the media, resulting in more consistent filtration. Flatbond can have areas of higher and lower fiber density, creating potential weak spots that lead to premature failure or inconsistent filtration performance.
Can I use this with water-based coolants?
Yes, though it's optimized for oil-based applications. For water-only coolants, you might get better cost-performance from our cellulose blend options. However, if your water-based system has any tramp oil contamination, this media is an excellent choice.
What basis weight should I choose?
It depends on your filtration requirements:
0.6-0.8 OSY: Light duty applications, finer filtration, shorter service life but better clarity
1.0 OSY: General purpose, most common choice, good balance of filtration and service life
1.5 OSY: Heavy-duty applications, coarser filtration, extended life in high-volume operations

Is this compatible with my specific filter brand?
This media works with virtually all pressure, vacuum, and gravity filter systems. We can custom convert to fit any filter size or configuration. If you'd like confirmation for your specific equipment, contact our team with your filter model information.
How long does this media typically last?
Service life depends on your specific application variables (particle load, flow rate, operating pressure, etc.). However, customers typically report excellent service life due to the uniform fiber distribution and strong construction. We can help estimate expected life based on your specific conditions—reach out to discuss your application.
