316L Stainless Steel Powder-Sintered Filter Plate, 20 µm Filtration Rating, Ø100 × 25 mm, 20 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 20 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 20 PPI porous structure has 1.27 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, 20 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.

Operating pressure, temperature, compatibility, and cleaning constraints for this 316L sintered filter plate are defined in this document. These constraints apply only to the Ø100 × 25 mm, 20 µm, 20 PPI variable product configuration.

  • Operating Limits: Keep normal use temperature at or below 500 °C and maximum working pressure at or below 3 MPa.
  • Process Compatibility: Confirm target flow, working pressure, temperature, media compatibility, and through-pore requirements before installation or ordering.
  • Pressure Handling: Increase pressure gradually and avoid rapid pressurization to protect the sintered porous structure.
  • Cleaning Compatibility: Select cleaning methods compatible with the retained material and process medium, including clean-fluid backwashing, clean-gas backblowing, ultrasonic cleaning, dilute acid or alkali, oxidizing agents, surfactants, or enzymes.
  • Surface Protection: Avoid impact, scratching, or concentrated tool pressure on the porous surface during cleaning and handling.

This procedure covers installation, pressure ramp-up, and regeneration cleaning for the Atomfair AF-SP20-A20 sintered filter plate. Only source-stated operational actions are included to avoid unsupported maintenance guidance.

Required Equipment: Clean-fluid backwashing system, Clean-gas backblowing system, Ultrasonic cleaner, Validated chemical cleaning agents

  1. Verify compatibility
    Verify that the process medium, working pressure, temperature, and through-pore requirement are compatible with the 316L filter plate before installation.
  2. Install with correct flow direction
    Install the plate in the filter housing with flow from the outside surface toward the clean side.
  3. Ramp pressure gradually
    Increase the differential pressure gradually during startup to avoid rapid pressurization.
  4. Regenerate the filter
    Initiate a validated backblowing or backwashing procedure when filtration efficiency falls below 50%.
  5. Clean the porous surface
    Clean the porous surface using a compatible physical or chemical method while avoiding impact, scratching, or concentrated tool pressure.

What is the maximum working pressure and temperature for the 316L stainless steel powder-sintered filter plate with 20 µm rating?

The filter plate has a maximum working pressure of ≤3 MPa and a normal use temperature of ≤500 °C. These limits are based on the 316L stainless steel powder-sintered construction, which provides mechanical rigidity and elevated-temperature service capability for liquid, gas, and process-filtration assemblies.

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

Yes, the powder-sintered metallic media is cleanable and reusable. Compatible cleaning methods include backblowing, backwashing, ultrasonic cleaning, and chemical cleaning with dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes. Avoid surface damage, rapid pressurization, and incompatible cleaning chemicals to maintain performance.

What are the key dimensional and structural specifications of the Ø100 × 25 mm 20 PPI filter plate?

The filter plate has a diameter of 100 mm and thickness of 25 mm, with a 20 PPI porous structure providing 1.27 mm nominal pore spacing, 30–45% porosity, and 4.4–5.6 g/cm³ bulk density. The 316L material density is 8.0 g/cm³, and the plate features uniform interconnected flow-through pores for stable gas or liquid passage with low initial resistance.

This 316L stainless steel powder-sintered filter plate provides 20 µm filtration with a 20 PPI porous structure, offering low initial resistance and regenerability via backblowing, backwashing, ultrasonic, or chemical cleaning. The porous surface is fragile, requiring careful handling, and operating conditions must be pre-verified for compatible application.

Positive

  • Low Initial Resistance with Uniform Pores: The uniform interconnected pore network supports stable gas or liquid passage with low initial resistance, reducing pressure drop across the filter plate.
  • Multiple Regeneration Options: The powder-sintered metallic media can be regenerated by compatible backblowing, backwashing, ultrasonic cleaning, or chemical cleaning, enabling repeated use.

Trade-offs

  • Fragile Porous Surface Requires Careful Handling: The porous surface can be damaged by impact, scratching, or concentrated tool pressure; pressure must be increased gradually and a validated cleaning procedure used if filtration efficiency drops below 50%.
  • Pre-Verification of Operating Conditions Required: Flow rate, working pressure, temperature, media compatibility, through-pore requirement, and dimensional tolerance must be confirmed before ordering to ensure proper fit and performance.
