Detailed Product Advantages
Our 304 stainless steel candle filter core is designed to outperform disposable filter cartridges in both cost-efficiency and sustainability. The wound wire construction creates a deep filtration medium that traps particles throughout the depth, offering higher dirt-holding capacity than surface-type filters. This means longer intervals between cleaning or replacement, reducing downtime and maintenance costs.
The 0.5 micron rating ensures exceptional clarity for your process fluids, protecting downstream equipment such as pumps, valves, and nozzles from wear caused by particulates. Stainless steel construction withstands aggressive chemicals, high temperatures, and repeated cleaning cycles without degradation. Unlike plastic or paper filters, this core can be fully backwashed, ultrasonically cleaned, or chemically treated for reuse, providing a sustainable solution that aligns with environmental goals.
The standard 10-inch length and 2.5-inch OD make it compatible with most industry-standard filter housings, while the 1/4 NPT connection allows easy integration into existing piping systems. With a 150 PSI rating, it is suitable for a wide range of pressure applications, from low-pressure gravity systems to moderate-pressure pumping stations.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a candle filter core and a cartridge filter?
A: A candle filter core is typically a rigid, reusable element made of wound stainless steel wire or sintered metal, while a cartridge filter is often a disposable, pleated or melt-blown media. The candle core can be cleaned and reused multiple times, offering lower long-term cost. -
Q: Can this filter core be backwashed?
A: Yes, the 304 stainless steel wound wire design allows for effective backwashing with water or air, restoring filtration capacity. However, the frequency and method depend on the fluid and particle load. -
Q: Is the 0.5 micron rating absolute or nominal?
A: Our filter core is rated at 0.5 micron absolute, meaning it captures at least 99.9% of particles of that size. Actual performance may vary based on operating conditions. -
Q: What is the maximum temperature this filter can handle?
A: The maximum continuous operating temperature is 450°F (232°C). For higher temperatures, please contact us for custom solutions. -
Q: Does the 1/4 NPT connection come with a gasket or O-ring?
A: The standard connection is a female NPT thread. For a leak-proof seal, we recommend using thread sealant or an appropriate O-ring on the male fitting (not included). -
Q: Can I get a custom length or different thread size?
A: Yes, we offer customization of length, outer diameter, thread type (e.g., NPT, BSP), and filter rating. Minimum order quantities may apply. Please contact our sales team for details. -
Q: How do I clean this filter core?
A: Common cleaning methods include backflushing with clean water, ultrasonic cleaning, or soaking in a mild acid or alkaline solution. Avoid using harsh chemicals that may damage the stainless steel. Always follow the recommended cleaning procedure for your specific application. -
Q: Is this filter core suitable for food-grade applications?
A: 304 stainless steel is generally considered food-safe. However, for specific food or beverage applications, please verify compliance with local regulations. We can provide material certificates upon request.
