The filter plate operates within defined temperature and pressure limits and requires careful cleaning to preserve its porous structure. Follow these constraints to prevent damage and maintain filtration efficiency.
- Temperature Limit: Normal use is limited to 500 °C; exceeding this may cause structural degradation.
- Pressure Limit: Maximum working pressure is 3 MPa; gradual pressurization is required to avoid damage.
- Media Compatibility: Confirm media compatibility before use to prevent chemical attack or pore blockage.
- Cleaning Procedure: Use compatible backblowing, backwashing, ultrasonic, or chemical cleaning methods; avoid impact and scratching.
- Efficiency Monitoring: If filtration efficiency falls below 50%, perform a validated backblowing or backwashing procedure.
This procedure outlines the sequential steps for safe operation and maintenance of the filter plate. Adhering to these steps ensures consistent filtration performance and extends the plate's service life.
Required Equipment: Ultrasonic cleaner, Backwashing system
- Verify Compatibility
Verify the filter plate's dimensions and material compatibility with the process fluid or gas before installation. - Install the Plate
Install the plate into the filter housing, ensuring the flow direction is from the outside surface toward the clean side. - Increase Pressure Gradually
Increase the inlet pressure gradually to the working pressure to avoid rapid pressure differentials. - Monitor Efficiency
Monitor filtration efficiency during operation and stop if it falls below 50%. - Perform Backblowing or Backwashing
Perform backblowing or backwashing using a clean fluid or gas to remove retained particles. - Use Alternative Cleaning
Use ultrasonic cleaning or compatible chemical cleaning methods if backblowing or backwashing is insufficient.
What is the maximum working pressure and temperature for the 316L stainless steel powder-sintered filter plate with 100 µm filtration rating?
The filter plate has a maximum working pressure of ≤3 MPa and a normal use temperature of ≤500 °C. These limits are based on the 316L stainless steel powder-sintered construction with 30–45% porosity and 4.4–5.6 g/cm³ bulk density, as stated in the technical specifications.
Can this Ø100 × 25 mm sintered filter plate be cleaned and reused, and what cleaning methods are compatible?
Yes, the metallic porous body can be regenerated using backblowing, backwashing, ultrasonic cleaning, or suitable chemical-cleaning procedures such as dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes. The product description explicitly lists these compatible cleaning methods and notes that surface damage, rapid pressurization, and incompatible chemicals should be avoided to maintain reusability.
What is the relationship between the 20 PPI pore density and the 100 µm filtration rating on this filter plate?
The 20 PPI (pores per inch) porous structure provides a nominal pore spacing of 1.27 mm and a porosity of 30–45%, while the 100 µm filtration rating defines the particle retention size. These are distinct parameters: PPI describes the macro-porous structure for permeability and flow distribution, whereas the filtration rating specifies the micron-level particle removal capability. The product combines both in a single sintered plate for applications requiring controlled flow and precise particle retention.
The 316L powder-sintered filter plate combines a 100 µm filtration rating with a 20 PPI porous structure, delivering uniform interconnected pores for low-resistance flow and a regenerable, cleanable metallic medium rated for service up to 500 °C and 3 MPa.
Positive
- Uniform interconnected pore network: The 20 PPI structure with 1.27 mm nominal pore spacing and 30–45% porosity provides stable gas or liquid passage with low initial resistance, supporting consistent filtration across the plate thickness.
- Regenerable and high-temperature compatible: The self-supporting 316L construction can be cleaned via backblowing, backwashing, ultrasonic, or validated chemical methods, and operates at normal temperatures up to 500 °C with a maximum working pressure of 3 MPa, enabling repeated use in demanding process conditions.
Trade-offs
- Handling and pressure ramp constraints: Rapid pressurization, impact, scratching, or concentrated tool pressure on the porous surface can reduce filtration efficiency; pressure must be increased gradually, and if efficiency drops below 50%, a validated backblowing or backwashing procedure should be applied.
- Cleaning chemistry and media compatibility validation: Cleaning procedures must be selected based on the retained material and process medium, requiring validation of chemical agents (e.g., dilute acids, alkalis, oxidizers, surfactants) and confirmation of media compatibility with the process fluid, flow, and pressure conditions before deployment.
