316L Stainless Steel Powder-Sintered Filter Plate, 50 µm Filtration Rating, Ø50 × 5 mm, 30 PPI, 1/5/10 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 Ø50 × 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 Ø50 × 5 mm plate is available in 1 pcs；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 Ø50 × 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 constraints for the 50 µm, 30 PPI 316L sintered filter plate. Adherence to these constraints is required to prevent media damage and maintain filtration performance.

  • Pressure and Temperature Limits: Operate within a maximum working pressure of 3 MPa and a normal use temperature of 500 °C to avoid structural failure.
  • Flow Direction Requirement: Direct flow from the outside surface toward the clean side to prevent pore blockage and media damage.
  • Cleaning Compatibility: Select cleaning methods based on the retained material, using compatible options such as backwashing, backblowing, ultrasonic cleaning, or approved chemical agents.
  • Handling Precautions: Avoid impact, scratching, or concentrated tool pressure on the porous surface to prevent compromising filtration integrity.

This procedure outlines the steps for initial installation, pressure ramp-up, and cleaning of the sintered filter plate. Following these steps ensures safe operation and extends the service life of the porous media.

Required Equipment: Clean filter housing, Pressure gauge, Backwashing or backblowing system, Ultrasonic cleaner (optional)

  1. Inspect the plate
    Inspect the filter plate for any visible damage or contamination before installation.
  2. Install the plate
    Install the plate into the filter housing, ensuring the flow direction is from the outside surface toward the clean side.
  3. Increase pressure gradually
    Increase the system pressure gradually to the operating level, not exceeding the 3 MPa maximum working pressure.
  4. Monitor filtration efficiency
    Monitor filtration efficiency during operation and check for any pressure drop or flow reduction.
  5. Initiate cleaning when efficiency drops
    Initiate a validated backblowing or backwashing procedure if filtration efficiency falls below 50%.
  6. Perform chemical cleaning if needed
    Perform chemical cleaning with compatible agents such as dilute acid, dilute alkali, or surfactants if backwashing is insufficient.
  7. Rinse and dry the plate
    Rinse the plate thoroughly with clean fluid and dry it completely before storage or reuse.

What is the maximum working pressure and temperature for the 316L stainless steel powder-sintered filter plate with 50 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 specified in the product technical specifications.

Can this 50 µm 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 explicitly states that cleanable porous construction supports repeat use when surface damage, rapid pressurization, and incompatible cleaning chemicals are avoided.

What is the nominal pore spacing and porosity of the 30 PPI porous structure in this filter plate?

The 30 PPI porous structure has a nominal pore spacing of 0.85 mm and a porosity range of 30–45%. These parameters are directly stated in the technical specifications for the AF-SP30-C50 model, supporting particle retention while maintaining gas or liquid permeability.

This 316L powder-sintered filter plate offers a 50 µm filtration rating with a 30 PPI interconnected porous structure, enabling low initial resistance and cleanable reuse via backblowing or ultrasonic cleaning, while requiring careful pressure ramp-up and validated cleaning protocols to avoid damage.

Positive

  • Cleanable metallic porous media: The powder-sintered 316L construction supports regeneration by backblowing, backwashing, ultrasonic cleaning, or compatible chemical procedures, enabling repeated use in laboratory and process filtration assemblies.
  • High temperature and pressure tolerance: Rated for normal use up to 500 °C and a maximum working pressure of 3 MPa, the filter plate is suitable for elevated-temperature and moderate-pressure filtration applications without loss of structural integrity.

Trade-offs

  • Mechanical handling sensitivity: The porous surface must be protected from impact, scratching, or concentrated tool pressure; pressure must be increased gradually to avoid structural damage, and filtration efficiency below 50% requires validated backblowing or backwashing procedures.
  • Pre-order compatibility verification required: Filtration rating, PPI, porosity, through-pore requirement, flow, working pressure, temperature, and media compatibility must be confirmed before ordering, as the through-pore rate is not specified and depends on the operating conditions.
