316L Stainless Steel Powder-Sintered Filter Plate, 50 µm Filtration Rating, Ø20 × 5 mm, 30 PPI, 5/10 pcs
Research-grade laboratory product
Product Overview

This 316L stainless steel powder-sintered filter plate combines a 50 µm filtration rating with a 30 PPI porous structure in a Ø20 × 5 mm format. Classified 316L powder is formed and sintered into a rigid microfiltration medium with stable pores and interconnected flow paths, supporting particle retention while maintaining gas or liquid permeability across the plate thickness. The self-supporting metallic construction suits compact assemblies that require a machinable, cleanable and reusable porous filter component.

The 30 PPI porous structure has 0.85 mm nominal pore spacing, 30–45% porosity and 4.4–5.6 g/cm³ bulk density. The 50 µm filtration rating supports precise selection for the intended particle-removal task. Uniform pore distribution, low initial resistance, mechanical rigidity and weldability support equipment integration, while the metallic porous body can be maintained with backblowing, backwashing, ultrasonic cleaning and suitable chemical-cleaning procedures.

The Ø20 × 5 mm plate is available in 5 pcs; 10 pcs packs for laboratory trials, replacement programs and small-batch equipment integration. Typical uses include pharmaceutical and chemical-process filtration, water treatment, food and beverage clarification, biotechnology, petrochemical processing, metallurgical operations, gas purification, fluid distribution, pump and tank filtration, coffee and sugar-processing equipment, medical filtration assemblies and other applications that use cleanable 316L porous media. Confirm flow, working pressure, temperature, media compatibility, through-pore requirement and dimensional tolerance before ordering.

Application Scope

This 50 µm, 30 PPI 316L sintered filter plate can be used in compatible liquid, gas and process-filtration assemblies that accept a Ø20 × 5 mm component. Application areas include pharmaceutical and chemical processing, water treatment, food and beverage clarification, biotechnology, petrochemical processing, metallurgy, gas purification, fluid distribution, oil and tank filtration, pump systems, coffee and sugar-processing equipment, medical filtration devices and cleanable porous-metal research fixtures.
PROCUREMENT CHECK: Confirm filtration rating, PPI, disc diameter, thickness, porosity, through-pore requirement, target flow, working pressure, temperature and media compatibility before quotation.
OPERATION NOTE: Increase pressure gradually. If filtration efficiency falls below 50%, use a validated backblowing or backwashing procedure and avoid impact, scratching or concentrated tool pressure on the porous surface.
CLEANING REVIEW: Select physical or chemical cleaning according to the retained material and process medium. Compatible options can include clean-fluid backwashing, clean-gas backblowing, ultrasonic cleaning, dilute acid, dilute alkali, oxidizing agents, surfactants or enzymes.
RFQ NOTE: Custom dimensions are available by e-mail consultation. Include the required diameter, thickness, PPI, filtration rating, package quantity and operating conditions when requesting dimensional review.

This filter plate requires gradual pressure increase to avoid damage and must be used within 500 °C and 3 MPa limits. Media compatibility and dimensional tolerance must be confirmed before installation, and only compatible cleaning methods should be applied to maintain performance.

  • Pressure and Temperature Limits: Operate within ≤500 °C normal use temperature and ≤3 MPa maximum working pressure, and increase pressure gradually during startup.
  • Media Compatibility: Confirm the filtration rating, PPI, disc dimensions, porosity, through-pore requirement, flow, working pressure, temperature, and media compatibility before ordering and installation.
  • Filtration Efficiency Monitoring: If filtration efficiency falls below 50%, use a validated backblowing or backwashing procedure and avoid impact, scratching, or concentrated tool pressure on the porous surface.
  • Cleaning and Regeneration: Select physical or chemical cleaning according to the retained material and process medium, using compatible options such as backwashing, backblowing, ultrasonic cleaning, dilute acid, alkali, oxidizing agents, surfactants, or enzymes.
  • Mechanical Care: Avoid surface damage, rapid pressurization, and incompatible cleaning chemicals to ensure repeated use.

Initial operation requires gradual pressure ramp and monitoring of filtration efficiency. When efficiency drops below 50%, execute a validated cleaning procedure to restore performance.

Required Equipment: Backblowing system, Backwashing system, Ultrasonic cleaner, Chemical cleaning agents

  1. Confirm compatibility
    Confirm the filtration rating, PPI, disc dimensions, porosity, through-pore requirement, target flow, working pressure, temperature, and media compatibility before installation.
  2. Gradual pressure ramp
    Increase pressure gradually during operation to avoid damage to the porous structure.
  3. Monitor efficiency
    Monitor filtration efficiency and use a validated backblowing or backwashing procedure if it falls below 50%.
  4. 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 50 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 should be confirmed against the specific flow, media compatibility, and through-pore requirements of the application.

Can this Ø20 × 5 mm sintered filter plate be cleaned and reused, and what cleaning methods are compatible?

Yes, the metallic porous body is designed for reuse and 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 cleaning method should be selected based on the retained material and process medium, while avoiding impact, scratching, or concentrated tool pressure on the porous surface.

What is the relationship between the 30 PPI pore density and the 50 µm filtration rating on this filter plate?

The 30 PPI (pores per inch) structure provides a nominal pore spacing of 0.85 mm and a porosity of 30–45%, which supports the 50 µm filtration rating by creating uniform interconnected flow paths for particle retention. The combination allows stable gas or liquid permeability with low initial resistance, but the through-pore rate must be confirmed against the required flow and pressure conditions for the specific application.

This 316L powder-sintered filter plate offers a 50 µm filtration rating with a 30 PPI porous structure (0.85 mm nominal pore spacing, 30–45% porosity) in a Ø20 × 5 mm disc, providing a rigid, weldable, and cleanable medium for liquid or gas filtration up to 500 °C and 3 MPa, though through-pore rate and media compatibility must be confirmed for the intended application.

Positive

  • Rigid, weldable 316L construction: The self-supporting metallic body can be welded, bonded, or mechanically integrated, enabling secure installation in compact filter housings and laboratory assemblies without additional support structures.
  • Cleanable and reusable porous media: The sintered structure supports regeneration via backblowing, backwashing, ultrasonic cleaning, or compatible chemical cleaning, allowing repeat use when surface damage and rapid pressurization are avoided.

Trade-offs

  • Through-pore rate must be confirmed: The through-pore rate is not specified and must be verified against required flow and pressure conditions, as it directly affects filtration efficiency and system design.
  • Sensitive to mechanical and chemical stress: The porous surface can be damaged by impact, scratching, or concentrated tool pressure, and incompatible cleaning chemicals may degrade the media, requiring careful handling and validated cleaning procedures.
