316L Stainless Steel Powder-Sintered Filter Plate, 20 µm Filtration Rating, Ø100 × 25 mm, 40 PPI, 1/2 pcs
Research-grade laboratory product
Product Overview

This 316L stainless steel powder-sintered filter plate combines a 20 µm filtration rating with a 40 PPI porous structure in a Ø100 × 25 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 40 PPI porous structure has 0.64 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 Ø100 × 25 mm plate is available in 1 pcs；2 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, 40 PPI 316L sintered filter plate can be used in compatible liquid, gas and process-filtration assemblies that accept a Ø100 × 25 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 operates within a normal use temperature of ≤500°C and a maximum working pressure of ≤3 MPa. Media compatibility must be confirmed before use, and the porous surface must be protected from impact, scratching, and concentrated tool pressure.

  • Temperature Limit: The normal use temperature must not exceed 500°C to avoid material degradation or pore collapse.
  • Pressure Limit: The maximum working pressure is 3 MPa; exceeding this limit may cause structural failure.
  • Media Compatibility: Confirm that the process fluid or gas is compatible with 316L stainless steel to prevent corrosion or fouling.
  • Handling Precautions: Avoid impact, scratching, or concentrated tool pressure on the porous surface to maintain filtration integrity.
  • Cleaning Compatibility: Select cleaning methods (backwashing, ultrasonic, dilute acid/alkali) that are compatible with both the retained material and the 316L substrate.

Gradually increase operating pressure and monitor filtration efficiency. Perform backblowing or backwashing when efficiency falls below 50%, and clean the plate using compatible methods.

Required Equipment: Backblowing system, Backwashing system, Ultrasonic cleaner

  1. Inspect the plate
    Inspect the filter plate for any surface damage or contamination before installation.
  2. Mount the plate
    Mount the plate in the filter housing ensuring flow direction from the outside surface toward the clean side.
  3. Increase pressure gradually
    Increase the operating pressure gradually to the desired working pressure, not exceeding 3 MPa.
  4. Monitor filtration efficiency
    Monitor filtration efficiency; if it drops below 50%, initiate a validated backblowing or backwashing procedure.
  5. Select cleaning method
    Select a cleaning method compatible with the retained material, such as backwashing, ultrasonic cleaning, or dilute acid or alkali.
  6. Avoid surface damage
    Avoid impact, scratching, or concentrated tool pressure on the porous surface during 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 filter plate has a normal use temperature of ≤500 °C and a maximum working pressure of ≤3 MPa. These limits are specified for the Ø100 × 25 mm, 40 PPI, 20 µm rated plate and must be confirmed against the target flow, media compatibility, and through-pore requirements before ordering.

Can this 20 µm sintered filter plate be cleaned and reused, and what cleaning methods are compatible?

Yes, the powder-sintered 316L construction supports regeneration via backblowing, backwashing, ultrasonic cleaning, or chemical cleaning with dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes. The manufacturer advises avoiding impact, scratching, concentrated tool pressure on the porous surface, and incompatible cleaning chemicals to maintain reusability.

What is the recommended flow direction and pore structure for this 40 PPI filter plate?

The recommended flow direction is normally from the outside surface toward the clean side. The 40 PPI porous structure provides a nominal pore spacing of 0.64 mm, porosity of 30–45%, and bulk density of 4.4–5.6 g/cm³, with uniform interconnected flow-through pores that support stable gas or liquid passage with low initial resistance.

The 316L powder-sintered filter plate delivers a 20 µm filtration rating in a robust Ø100 × 25 mm format with 40 PPI porous structure, supporting gas/liquid permeability and particle retention up to 3 MPa and 500 °C. Its cleanable, self-supporting construction suits reusable process filtration, but operational success depends on gradual pressurization, media compatibility confirmation, and validated cleaning to maintain efficiency.

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 process filtration systems.
  • Cleanable and reusable porous metal: The sintered 316L structure can be regenerated via backblowing, backwashing, ultrasonic cleaning, or compatible chemical agents, supporting repeated use and reduced consumable replacement frequency.

Trade-offs

  • Requires careful pressure and handling: Pressure must be increased gradually, and the porous surface must avoid impact, scratching, or concentrated tool pressure; if filtration efficiency drops below 50%, a validated backblowing or backwashing procedure is required.
  • Pre-installation compatibility verification: Through-pore rate, flow, working pressure, temperature, media compatibility, and dimensional tolerance must be confirmed with the supplier before ordering to ensure the plate meets the intended application's requirements.
