Detailed Advantages
- Temperature Resistance: 316L stainless steel withstands continuous operation from -20°C to +400°C (depending on seal material), making it suitable for both hot and cold filtration.
- Chemical Compatibility: Resistant to most acids, alkalis, solvents, and chlorides, ensuring long service life in aggressive chemical environments.
- High Flow with Low Pressure Drop: The skeleton core design with large open area minimizes resistance, reducing energy consumption in pumping systems.
- Reusable & Washable: Unlike disposable cartridges, this stainless steel filter can be cleaned by backwashing, ultrasonic cleaning, or chemical cleaning, offering significant cost savings over time.
- Customizable Options: Available in different micron ratings (1, 10, 20, 50 µm), lengths (10, 20, 30, 40 inch), and end cap configurations (open, closed, 222, 226, etc.). We can also provide custom O-ring materials and surface finishes.
- Ease of Installation: Standard 2.5-inch outer diameter fits most commercial filter housings. Double O-ring design ensures a secure, tool-free seal.

Frequently Asked Questions (FAQ)
Q1: What is the difference between a skeleton core filter and a regular mesh filter?
A: A skeleton core filter uses a rigid perforated or expanded metal core that provides structural support, allowing for higher differential pressure and better flow distribution. Regular mesh filters often have a weaker support structure. The skeleton core is ideal for high-pressure and high-flow applications.
Q2: Can this cartridge be used for food-grade applications?
A: Yes. The 316L stainless steel is food-grade compliant, and the surface finish can be electropolished to meet sanitary standards. The double O-ring seal (available in FDA-grade silicone) ensures no contamination. We recommend specifying the appropriate seal material for your specific food product.
Q3: What is the maximum operating temperature and pressure?
A: The maximum operating temperature depends on the O-ring material: EPDM up to 150°C, Viton up to 200°C, Silicone up to 250°C. The stainless steel structure can withstand up to 30 bar differential pressure under standard conditions. For higher pressure requirements, please consult our engineering team for custom design.
Q4: How do I clean and reuse the cartridge?
A: The cartridge can be cleaned by backwashing with clean water or chemicals, ultrasonic cleaning, or steam sterilization. Avoid using abrasive tools that may scratch the surface. Regular cleaning can extend the lifespan significantly, making it a cost-effective solution compared to disposable filters.
Q5: Does the double O-ring seal prevent bypass completely?
A: Yes. The double O-ring design creates two positive sealing points, effectively eliminating any bypass of unfiltered fluid. This is critical for applications requiring absolute filtration integrity, such as pharmaceutical or semiconductor manufacturing.
Q6: Can I get a custom length or micron rating?
A: Absolutely. We offer customization in lengths from 10 to 60 inches, micron ratings from 1 to 200 µm, and various end cap configurations (open, closed, 222, 226, etc.). Please provide your specifications for a tailored solution.
Q7: What is the typical lead time for orders?
A: For standard 40-inch cartridges, the lead time is 15–20 working days. Custom orders may require 25–30 days depending on complexity. We also keep a stock of popular sizes for urgent requirements – please contact our sales team to check availability.
Q8: Do you offer samples before bulk purchase?
A: Yes, we provide samples (with freight charges) for evaluation. Once the sample is approved, we can proceed with mass production. Sample cost can be deducted from the first bulk order.
