316L Stainless Steel Powder-Sintered Filter Plate, 50 µm Filtration Rating, Ø30 × 3 mm, 20 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 20 PPI porous structure in a Ø30 × 3 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 20 PPI porous structure has 1.27 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 Ø30 × 3 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, 20 PPI 316L sintered filter plate can be used in compatible liquid, gas and process-filtration assemblies that accept a Ø30 × 3 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.

Service is bounded by the supplier-stated pressure, temperature, and media-compatibility envelope for this sintered plate. Mechanical and cleaning procedures must preserve porous-surface integrity.

  • Pressure and Temperature Envelope: Do not operate the plate above the rated working pressure or normal-use temperature stated for the selected filter configuration.
  • Flow Direction: Configure process flow from the outside surface toward the clean side for normal filtration service.
  • Surface Handling: Avoid impact, scratching, or concentrated tool pressure on the porous surface during handling and installation.
  • Performance Decline: Initiate a validated backblowing or backwashing procedure if filtration efficiency falls below 50% before considering disassembly.
  • Cleaning Media Compatibility: Select cleaning chemicals according to the retained material and process medium, using dilute acids, dilute alkalis, oxidizing agents, surfactants, or enzymes as compatible options.

Install the plate with correct orientation and pressurize gradually after verifying seat conditions. Regenerate through validated backflushing, backblowing, or chemical cleaning when filtration efficiency drops.

Required Equipment: Clean-fluid backwashing device, Clean-gas backblowing device, Ultrasonic bath

  1. Inspect the Plate and Seat
    Inspect the filter plate and its housing seat for burrs, scratches, or dimensional mismatch before installation.
  2. Orient the Plate
    Place the plate in the housing with the intended flow direction from the outside surface toward the clean side.
  3. Pressurize Gradually
    Increase pressure gradually to the working pressure while checking the assembly for leaks or bypass.
  4. Verify Filtration Performance
    Verify that filtrate flow and clarity remain at the target values for the intended filtration duty.
  5. Regenerate When Efficiency Drops
    Initiate a validated backblowing or backwashing regeneration when filtration efficiency falls below 50%.
  6. Clean the Porous Surface
    Clean the porous surface using ultrasonic, dilute acid, dilute alkali, oxidizing-agent, surfactant, or enzyme procedures matched to the retained material.
  7. Reinstall and Re-certify
    Reinstall the regenerated plate and restore operating pressure gradually while confirming filtration performance.

What is the maximum working pressure and normal use temperature for the 316L 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 and are stated in the product specifications. Confirm compatibility with your specific operating conditions before ordering.

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 procedures. The product description notes that clean-fluid backwashing, clean-gas backblowing, ultrasonic cleaning, dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes are compatible options. Avoid surface damage, rapid pressurization, and incompatible cleaning chemicals to support repeat use.

What is the relationship between the 50 µm filtration rating and the 20 PPI pore density on this filter plate?

The 50 µm filtration rating specifies the particle retention size, while the 20 PPI (pores per inch) 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. The through-pore rate must be confirmed with the required flow and pressure conditions for your application.

This 316L stainless steel powder-sintered filter plate provides a 50 µm filtration rating via a 20 PPI porous structure with 30–45% porosity and interconnected flow paths, enabling particle retention with low initial resistance in gas or liquid applications up to 500 °C and 3 MPa, but requires careful cleaning validation and pre-order confirmation of operating conditions.

Positive

  • 50 µm filtration with 20 PPI structure: Combines a 50 µm filtration rating with 1.27 mm nominal pore spacing and 30–45% porosity, supporting particle retention while maintaining gas or liquid permeability through uniform interconnected pores.
  • Rigid, cleanable, and weldable 316L construction: The self-supporting powder-sintered metallic body can be welded, bonded, or mechanically integrated, and is regenerable via backblowing, backwashing, ultrasonic cleaning, or compatible chemical cleaning, enabling repeat use.

Trade-offs

  • Cleaning and handling sensitivity: The porous surface is vulnerable to impact, scratching, or concentrated tool pressure; cleaning must follow validated backblowing/backwashing procedures and avoid incompatible chemicals to maintain filtration efficiency above 50%.
  • Pre-order technical validation required: Flow, working pressure, temperature, media compatibility, through-pore requirement, and dimensional tolerance must be confirmed before ordering, as the plate is not universally suitable without application-specific verification.
