The filter plate must be operated within a maximum working pressure of 3 MPa and a normal use temperature limit of 500°C. To maintain filtration performance, gradual pressure increase is required, and the porous surface must be protected from impact, scratching, or concentrated tool pressure.
- Cleaning and Regeneration: Select physical or chemical cleaning methods such as backblowing, backwashing, ultrasonic cleaning, or compatible chemical agents based on the retained material and process medium.
- Performance Monitoring: If filtration efficiency falls below 50%, initiate a validated backblowing or backwashing procedure to restore flow.
- Media Compatibility: Confirm media compatibility, working pressure, temperature, and through-pore requirements before ordering to ensure proper integration.
- Maintenance Precautions: Avoid impact, scratching, or concentrated tool pressure on the porous surface during handling and cleaning.
- Dimensional Confirmation: Verify disc diameter, thickness, and dimensional tolerance against the assembly requirements prior to use.
Prior to use, confirm that the filtration rating, disc dimensions, working pressure, temperature, and media compatibility are within specified limits. During operation, increase pressure gradually and monitor filtration efficiency; if efficiency drops below 50%, perform a validated backblowing or backwashing procedure.
Required Equipment: Backblowing equipment, Backwashing equipment, Ultrasonic cleaner, Cleaning chemicals
- Confirm requirements
Confirm that the filtration rating, disc dimensions, working pressure, temperature, and media compatibility meet the application requirements. - Install with correct flow direction
Install the filter plate in the housing with the flow direction from the outside surface toward the clean side. - Gradually increase pressure
Increase the working pressure gradually to the operating level while monitoring for leaks or pressure drops. - Monitor efficiency and act
Monitor filtration efficiency; if it falls below 50%, initiate a validated backblowing or backwashing procedure. - Select cleaning method
Select a compatible cleaning method based on the retained material and process medium.
What is the maximum working pressure and temperature for the 316L stainless steel powder-sintered filter plate with 30 µm filtration rating?
The filter plate has a normal use temperature of ≤500 °C and a maximum working pressure of ≤3 MPa. These limits are based on the 316L stainless steel powder-sintered construction with a bulk density of 4.4–5.6 g/cm³ and a porosity of 30–45%, as stated in the product specifications.
Can this Ø30 × 3 mm sintered filter plate be cleaned and reused, and what cleaning methods are compatible?
Yes, the powder-sintered metallic media can be regenerated by compatible backblowing, backwashing, ultrasonic cleaning, or chemical cleaning using dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes. The product notes that surface damage, rapid pressurization, and incompatible cleaning chemicals should be avoided to maintain reusability.
What is the relationship between the 30 µm filtration rating and the 20 PPI porous structure on this filter plate?
The 30 µm filtration rating specifies the particle retention size, while the 20 PPI porous structure provides a nominal pore spacing of 1.27 mm and a porosity of 30–45%. The combination supports particle retention with low initial resistance and interconnected flow paths for gas or liquid permeability across the 3 mm thickness, as described in the product overview.
The 30 µm, 20 PPI 316L sintered filter plate offers a rigid, cleanable porous medium for liquid and gas filtration in compact Ø30 mm assemblies, with a 500°C temperature limit and 3 MPa pressure rating, requiring compatibility verification and gradual pressure ramping to avoid structural damage.
Positive
- Stable interconnected pore structure: The 30–45% porosity and 1.27 mm nominal pore spacing provide uniform flow paths with low initial resistance, enabling consistent particle retention and permeability across the plate thickness.
- Self-supporting and regenerable design: The rigid 316L sintered body can be welded, bonded, or mechanically integrated into assemblies, and supports backblowing, backwashing, ultrasonic, or chemical cleaning for repeated use when properly handled.
Trade-offs
- Temperature and pressure constraints: Normal use is limited to ≤500 °C and maximum working pressure ≤3 MPa, restricting application in high-temperature or high-pressure processes without further validation.
- Cleaning and handling sensitivity: Regeneration requires compatible cleaning procedures and gradual pressure changes; impact, scratching, or concentrated tool pressure on the porous surface can degrade filtration performance.
