316L Stainless Steel Powder-Sintered Filter Plate, 20 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 20 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 20 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 20 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 document defines the operational limits and maintenance requirements for the 316L stainless steel powder-sintered filter plate. It details temperature and pressure thresholds, cleaning procedures, and handling precautions to ensure safe and effective filtration.

  • Temperature and Pressure Limits: The filter plate is rated for normal use up to 500 °C and a maximum working pressure of 3 MPa, with flow normally directed from the outside surface toward the clean side.
  • Pressure Ramping: Gradually increase pressure during operation to prevent mechanical shock to the porous structure.
  • Surface Protection: Avoid impact, scratching, or concentrated tool pressure on the porous surface to prevent damage.
  • Cleaning Regeneration: Regenerate the filter using validated backblowing, backwashing, ultrasonic cleaning, or compatible chemical cleaning methods.
  • Compatibility Verification: Confirm media compatibility, through-pore requirements, and dimensional tolerances before ordering or installation.

This procedure outlines the safe operation and cleaning steps for the 316L stainless steel filter plate. Follow these steps to maintain filtration efficiency and extend service life.

Required Equipment: Backblowing equipment, Backwashing system, Ultrasonic cleaner, Chemical cleaning solution

  1. Verify Compatibility
    Verify filtration rating, material compatibility, and dimensional tolerance before installation.
  2. Install Filter Plate
    Install the filter plate in the housing, ensuring the flow direction is from the outside surface toward the clean side.
  3. Increase Pressure Gradually
    Gradually increase the operating pressure to the maximum working pressure of 3 MPa.
  4. Monitor Efficiency
    Monitor filtration efficiency and pressure drop during service.
  5. Initiate Cleaning
    When filtration efficiency falls below 50%, initiate a validated backblowing or backwashing procedure.
  6. Apply Additional Cleaning
    For stubborn fouling, apply ultrasonic cleaning or compatible chemical cleaning agents.
  7. Prevent Surface Damage
    Avoid impact, scratching, or concentrated tool pressure on the porous surface throughout handling and cleaning.

What is the maximum working pressure and temperature for the 316L stainless steel powder-sintered filter plate with 20 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 a porosity of 30–45%, as specified in the product technical data.

Can this Ø20 × 5 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 description explicitly states that the porous body supports repeat use when surface damage, rapid pressurization, and incompatible cleaning chemicals are avoided.

What is the relationship between the 20 µm filtration rating and the 30 PPI pore density for this filter plate?

The 20 µm filtration rating defines the particle retention size, while the 30 PPI (pores per inch) structure provides a nominal pore spacing of 0.85 mm and a porosity of 30–45%. These parameters together support particle retention with low initial resistance and stable gas or liquid permeability across the plate thickness, as stated in the product overview and technical specifications.

This 316L stainless steel powder-sintered filter plate offers 20 µm filtration with a 30 PPI porous structure in a compact Ø20×5 mm disc, supporting liquid and gas microfiltration with cleanable, reusable metallic media up to 500°C and 3 MPa.

Positive

  • 20 µm filtration with 30 PPI porous structure: The combination of 20 µm filtration rating and 30 PPI (0.85 mm nominal pore spacing) allows effective particle retention with stable gas/liquid flow and low initial resistance, suitable for microfiltration tasks.
  • Regenerable metallic filter media: The powder-sintered 316L structure supports backblowing, backwashing, ultrasonic, and chemical cleaning, enabling repeat use and reduced consumable waste compared to disposable filters.

Trade-offs

  • Operating pressure and temperature limits: The filter plate is rated for ≤3 MPa working pressure and ≤500°C normal use, which may restrict use in high-pressure or high-temperature processes beyond these limits.
  • Requires careful handling and cleaning validation: The porous surface is susceptible to damage from rapid pressurization, impact, or scratching; cleaning procedures must be validated for the retained material to avoid compromising filtration efficiency.
