These constraints govern operation and maintenance of the 316L powder-sintered filter plate without restating dimensional or media specifications. They address gradual pressurization, surface integrity, cleaning-chemical compatibility, and integration handling.
- Gradual pressurization: Increase pressure gradually during operation to avoid rapid pressurization that could damage the sintered porous structure.
- Efficiency recovery: Apply a validated backblowing or backwashing procedure when filtration efficiency falls below 50%.
- Surface protection: Avoid impact, scratching, or concentrated tool pressure on the porous surface during handling and cleaning.
- Cleaning-chemical compatibility: Select cleaning chemicals compatible with the retained material and process medium, including dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes.
- Integration handling: Preserve the porous structure during welding, bonding, or mechanical integration to prevent damage to the sintered media.
This procedure covers installation, controlled pressurization, and routine regeneration of the filter plate. The steps follow the manufacturer operation note and cleaning review directions.
Required Equipment: Validated backblowing or backwashing system, Ultrasonic cleaner
- Inspect the plate
Inspect the filter plate for visible surface damage before installation. - Mount the plate
Mount the plate in the housing so flow passes from the outside surface toward the clean side. - Pressurize gradually
Increase system pressure gradually to the target working pressure. - Monitor filtration efficiency
Monitor filtration efficiency during service and initiate a validated backblowing or backwashing procedure if it falls below 50%. - Clean after use
Clean the plate by a compatible method such as clean-fluid backwashing, gas backblowing, ultrasonic cleaning, or selected chemical cleaning.
What is the maximum working pressure and temperature for the 316L powder-sintered filter plate with 100 µm filtration rating?
The maximum working pressure is ≤3 MPa, and the normal use temperature is ≤500 °C. These limits are based on the 316L stainless steel powder-sintered construction with a bulk density of 4.4–5.6 g/cm³ and porosity of 30–45%, as stated in the product specifications.
Can this Ø20 × 5 mm sintered filter plate be cleaned and reused, and what cleaning methods are compatible?
Yes, the metallic porous body supports regeneration via backblowing, backwashing, ultrasonic cleaning, and suitable chemical-cleaning procedures such as dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes. However, surface damage, rapid pressurization, and incompatible cleaning chemicals should be avoided to maintain performance.
What is the relationship between the 110 PPI pore density and the 100 µm filtration rating for particle retention?
The 110 PPI porous structure provides a nominal pore spacing of 0.23 mm and porosity of 30–45%, which together support a 100 µm filtration rating for particle retention. The interconnected flow-through pore network enables stable gas or liquid permeability with low initial resistance, but the through-pore rate must be confirmed against required flow and pressure conditions before ordering.
This 316L stainless steel powder-sintered filter plate offers a 100 µm filtration rating with a 110 PPI porous structure in a Ø20 × 5 mm disc format, providing stable pore distribution and interconnected flow paths for gas or liquid microfiltration. Its self-supporting metallic construction withstands temperatures up to 500 °C and pressures up to 3 MPa, while cleanability via backblowing, backwashing, or ultrasonic methods supports reusable operation in pharmaceutical, chemical, and biotech applications.
Positive
- High temperature and pressure tolerance: Rated for normal use up to 500 °C and maximum working pressure of 3 MPa, enabling deployment in elevated-temperature and pressurized filtration assemblies without compromising structural integrity.
- Cleanable and reusable metallic media: The powder-sintered 316L construction supports regeneration via backblowing, backwashing, ultrasonic cleaning, or compatible chemical procedures, extending service life and reducing replacement frequency in laboratory and process environments.
Trade-offs
- Sensitive to mechanical shock and surface damage: The porous surface must be protected from impact, scratching, and concentrated tool pressure; pressure should be increased gradually to avoid structural degradation, requiring careful handling during installation and operation.
- Through-pore rate requires application-specific confirmation: The through-pore rate is not fixed and must be verified against target flow and pressure conditions, meaning the filter plate is not a universal drop-in component without prior compatibility assessment.
