316L Sintered Filter Plate 30μm 30 PPI Ø50×5mm ATOMFAIR®

316L Stainless Steel Powder-Sintered Filter Plate, 30 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 30 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 30 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.

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.

The filter plate must be operated within the stated maximum working pressure and normal-use temperature limits to prevent structural failure. The porous surface is sensitive to impact, scratching, and concentrated tool pressure, which can reduce filtration efficiency.

Pressure and Temperature Limits: Operate the plate within the maximum working pressure of 3 MPa and normal-use temperature of 500 °C to avoid permanent deformation or loss of filtration performance.
Surface Integrity: Avoid impact, scratching, or concentrated tool pressure on the porous surface to prevent damage that can compromise filtration efficiency.
Cleaning Compatibility: Select cleaning chemicals that are compatible with 316L stainless steel and the process medium to avoid corrosion or degradation.
Regeneration Requirement: If filtration efficiency falls below 50%, regenerate the plate using a validated backblowing or backwashing procedure.
Gradual Pressurization: Increase system pressure gradually to prevent rapid pressurization that could damage the porous structure.

FAQ

What is the difference between the 30 µm filtration rating and the 30 PPI pore density on this 316L sintered filter plate?

The 30 µm filtration rating specifies the particle size retained by the porous structure, while the 30 PPI (pores per inch) describes the pore density and spacing. For this Ø50 × 5 mm plate, the 30 PPI structure yields a nominal pore spacing of 0.85 mm, porosity of 30–45%, and bulk density of 4.4–5.6 g/cm³. The filtration rating and PPI are independent parameters; selecting the correct combination depends on the required particle retention and flow permeability for your specific application.

Can this 316L powder-sintered filter plate be welded or integrated into an existing stainless steel assembly?

Yes, the rigid, self-supporting 316L construction can be welded, bonded, or mechanically integrated as required. The metallic porous body is weldable, but care must be taken to avoid damaging the porous surface through impact, scratching, or concentrated tool pressure. The plate is designed for compact assemblies that require a machinable, cleanable, and reusable porous filter component.

What are the recommended cleaning and regeneration procedures for this sintered filter plate?

The powder-sintered metallic media can be regenerated using compatible backblowing, backwashing, ultrasonic cleaning, or suitable chemical-cleaning procedures such as dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes. Avoid rapid pressurization and incompatible cleaning chemicals. If filtration efficiency falls below 50%, use a validated backblowing or backwashing procedure to restore performance.

Assessment

This 316L stainless steel powder-sintered filter plate (Ø50 × 5 mm, 30 µm rating, 30 PPI) provides a rigid, cleanable, and reusable metallic microfiltration medium with uniform interconnected pores, supporting elevated-temperature service up to 500 °C and working pressures up to 3 MPa. The 30–45% porosity and 0.85 mm nominal pore spacing deliver low initial resistance, while the self-supporting construction allows welding or bonding for compact assemblies.

Positive

High temp and pressure tolerance: Rated for normal use up to 500 °C and maximum working pressure up to 3 MPa, enabling deployment in demanding liquid and gas filtration applications.
Cleanable and reusable metallic media: The powder-sintered 316L construction supports multiple regeneration cycles via backblowing, backwashing, ultrasonic, or compatible chemical cleaning, reducing replacement frequency.

Trade-offs

Pressure ramp and surface fragility: Pressure must be increased gradually, and the porous surface is vulnerable to impact, scratching, or concentrated tool pressure, which can degrade filtration efficiency.
Cleaning validation required: Physical or chemical cleaning method must be validated against the retained material and process medium; incompatible cleaning agents can damage the porous structure.
