structure advantages
Stainless steel melt filter cartridges feature a precise layered structure:
- Core Filter Layer: Composed of multiple layers of standard stainless steel woven mesh with varying mesh sizes, formed into a single unit through diffusion sintering or high-pressure pressing, ensuring precise pore size and high strength.
- Protective and Support Layer: An internal and external perforated stainless steel skeleton provides comprehensive support for the fine filter mesh, preventing deformation or crushing under high pressure differentials.
- End Sealing Structure: Utilizing stainless steel end caps and professionally welded to the filter media, completely eliminating bypass leakage and ensuring all fluids undergo effective filtration.

FAQ
Q1: Can this candle filter cartridge be completely cleaned?
A1: Yes. As an all-metal stainless steel filter, it can thoroughly remove contaminants deep within the filter media through powerful methods such as backwashing and ultrasonic cleaning, restoring its performance to like-new condition. This is unmatched by paper or disposable filter cartridges.
Q2: What is the difference between a stainless steel candle filter cartridge and a regular sintered mesh filter cartridge?
A2: The main difference lies in the optimized structure and performance. Candle filter cartridges are designed for vertical installation and high-pressure conditions, typically featuring a larger filtration area and stronger resistance to collapse.
Q3: How to choose between 304 and 316L stainless steel?
A3: 304 stainless steel is suitable for most general industrial environments, offering good corrosion resistance and cost-effectiveness.
316L stainless steel contains molybdenum, providing superior resistance to chloride ion corrosion and pitting corrosion, making it the preferred choice for chemical, marine, or high-salt environments.
Q4: What is the normal service life of a filter cartridge?
A4: Its physical lifespan is extremely long, reaching several years. The actual cleaning and replacement cycle depends on the contamination level of the inlet oil and the system's operating conditions. Cleaning is required when the filter differential pressure reaches a set value, and the filter can be reused after cleaning.
Q5: Besides the model number, what other information is needed to ensure compatibility when purchasing?
A5: To ensure everything goes smoothly, we recommend providing:
- A clear photo of the old filter element (including label and dimensions).
- The brand and model of the filter housing.
- Detailed properties of the filter media (e.g., oil type, temperature, viscosity).
- Your system operating pressure and target cleanliness level.
