316L Sintered Filter Plate 100μm Ø20×5 mm ATOMFAIR®

316L Stainless Steel Powder-Sintered Filter Plate, 100 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 100 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 100 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 100 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 316L powder-sintered filter plate must be operated within its rated service temperature and pressure limits and with media-compatible process fluids. The porous structure is sensitive to rapid pressure changes, surface impact, and incompatible cleaning chemistries, so gradual pressurization and validated regeneration procedures are required.

Pressure Ramp Constraint: Increase process pressure gradually to avoid rapid pressurization that can damage the sintered porous structure.
Surface Integrity Constraint: Avoid impact, scratching, or concentrated tool pressure on the porous surface during handling and cleaning.
Cleaning Compatibility Constraint: Select physical or chemical cleaning based on the retained material and process medium, using only compatible backblowing, backwashing, ultrasonic, dilute acid, dilute alkali, oxidizing, surfactant, or enzyme procedures.
Regeneration Trigger: Regenerate the filter by validated backblowing or backwashing when filtration efficiency falls below 50%.
Flow Orientation Constraint: Install the plate so normal process flow passes from the outside surface toward the clean side.

HowTo

This procedure describes installation, pressurization, and regeneration of a 316L powder-sintered filter plate in a compatible filtration assembly. It applies only to cleanable metallic porous media that are handled without impact, scratching, or concentrated tool pressure.

Required Equipment: Clean-fluid backwashing system, Clean-gas backblowing supply, Ultrasonic cleaner

Visual Inspection
Inspect the filter plate for visible damage, scratches, or contamination before installation.
Installation Orientation
Install the plate in the housing with process flow entering from the outside surface toward the clean side.
Gradual Pressurization
Pressure the system gradually and monitor differential pressure to avoid rapid pressurization.
Regeneration Trigger
Regenerate the plate when filtration efficiency falls below 50% using a validated backblowing or backwashing procedure.
Final Cleaning
Clean the plate ultrasonically or with compatible chemical agents if backblowing or backwashing does not restore flow.

FAQ

What is the maximum working pressure and temperature for the 316L stainless steel powder-sintered filter plate with 100 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 with 30–45% porosity and 4.4–5.6 g/cm³ bulk density, as stated in the product specifications.

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

What is the relationship between the 30 PPI pore density and the 100 µm filtration rating on this filter plate?

The 30 PPI porous structure provides a nominal pore spacing of 0.85 mm and 30–45% porosity, while the 100 µm filtration rating defines the particle retention size. These parameters work together: the interconnected flow-through pore network supports gas or liquid permeability with low initial resistance, and the filtration rating allows precise selection for the intended particle-removal task. The product combines both specifications in a single Ø20 × 5 mm disc.

Assessment

This 316L powder-sintered filter plate combines a 100 µm filtration rating with a 30 PPI porous structure in a Ø20 × 5 mm format, using 30–45% porosity and 0.85 mm nominal pore spacing to deliver uniform, interconnected flow paths. The cleanable, weldable metallic medium is suitable for compact liquid and gas filtration assemblies within the stated ≤500 °C and ≤3 MPa operating envelope.

Positive

Uniform interconnected pore network with low resistance: The 30 PPI sintered structure provides 30–45% porosity with 0.85 mm nominal pore spacing, and the uniform interconnected through-pore network supports stable gas or liquid passage with low initial resistance across the 5 mm plate thickness.
Cleanable, weldable self-supporting stainless medium: The rigid 316L powder-sintered body can be welded, bonded, or mechanically integrated, and is regenerable via compatible backblowing, backwashing, ultrasonic, or chemical cleaning for repeat filtration service.

Trade-offs

Temperature and pressure operating envelope: Normal use is limited to ≤500 °C and maximum working pressure to ≤3 MPa, with flow normally directed from the outside surface toward the clean side; through-pore rate, media compatibility, and process conditions must be confirmed before service.
Surface handling and regeneration constraints: Pressure should be increased gradually, and the porous surface must be protected from impact, scratching, or concentrated tool pressure; when filtration efficiency drops below 50%, only validated backblowing or backwashing procedures should be used.
