316L Sintered Filter Plate 100μm 20PPI Ø30×3mm ATOMFAIR®

316L Stainless Steel Powder-Sintered Filter Plate, 100 µm Filtration Rating, Ø30 × 3 mm, 20 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 20 PPI porous structure in a Ø30 × 3 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 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 Ø30 × 3 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, 20 PPI 316L sintered filter plate can be used in compatible liquid, gas and process-filtration assemblies that accept a Ø30 × 3 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 stainless steel sintered filter plate has maximum operating limits of 500°C and 3 MPa. Proper handling avoids surface damage, and cleaning must use compatible methods for 316L stainless steel.

Temperature and Pressure Limits: Do not exceed 500°C operating temperature or 3 MPa working pressure to prevent structural failure.
Handling Precautions: Avoid impact, scratching, or concentrated tool pressure on the porous surface to maintain filtration integrity.
Cleaning Compatibility: Select cleaning methods (backblowing, backwashing, ultrasonic, chemical) that are compatible with 316L stainless steel and the retained material.
Flow Direction: Install the filter plate with flow direction from the outside surface toward the clean side as specified.
Pressure Increase: Increase operating pressure gradually to avoid damaging the porous structure.

HowTo

Inspect the filter plate for damage before installation. Install with correct orientation and gradually increase pressure while monitoring efficiency.

Inspect the filter plate
Inspect the filter plate for visible damage, contamination, or deformation before installation.
Install with correct orientation
Install the filter plate in the housing ensuring the flow direction is from the outside surface toward the clean side.
Increase pressure gradually
Increase the operating pressure gradually to the required level while monitoring the differential pressure.
Monitor filtration efficiency
Monitor filtration efficiency; if it falls below 50%, initiate a cleaning procedure using a validated backblowing or backwashing method.
Select cleaning method
Select a compatible cleaning method such as backblowing, backwashing, ultrasonic cleaning, or chemical cleaning based on the retained material.
Handle carefully
Handle the filter plate carefully to avoid impact, scratching, or concentrated tool pressure on the porous surface during handling and cleaning.

FAQ

What is the maximum working pressure and temperature for the 316L 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 Ø30 × 3 mm sintered filter plate be cleaned and reused, and what methods are compatible?

Yes, the metallic porous body supports regeneration via backblowing, backwashing, ultrasonic cleaning, and suitable chemical-cleaning procedures such as dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes. The product description explicitly lists these compatible cleaning methods for repeat use, provided surface damage, rapid pressurization, and incompatible chemicals are avoided.

What is the relationship between the 20 PPI pore density and the 100 µm filtration rating on this filter plate?

The 20 PPI (pores per inch) structure provides a nominal pore spacing of 1.27 mm and a porosity of 30–45%, while the 100 µm filtration rating defines the particle size retained. These are independent but complementary parameters: the PPI governs the porous network's flow capacity and mechanical integrity, whereas the filtration rating determines the retention precision. The product combines both to support particle retention with low initial resistance in gas or liquid applications.

Assessment

This 316L powder-sintered filter plate offers a 100 µm filtration rating with a 20 PPI porous structure, providing a balance of particle retention and permeability for liquid and gas applications. The Ø30 × 3 mm disc geometry and self-supporting metallic construction enable integration into compact assemblies, with cleanability via backblowing or ultrasonic methods supporting reuse.

Positive

Cleanable and reusable metallic media: The powder-sintered 316L structure can be regenerated using backblowing, backwashing, ultrasonic cleaning, or compatible chemical procedures, reducing replacement frequency in laboratory and process filtration.
High-temperature and pressure tolerance: Rated for normal use up to 500 °C and maximum working pressure of 3 MPa, the plate supports elevated-temperature and moderate-pressure filtration without structural degradation.

Trade-offs

Requires gradual pressure ramp-up: Operation notes specify increasing pressure gradually; rapid pressurization may damage the porous surface or reduce filtration efficiency, necessitating careful process control.
Through-pore rate must be confirmed: The through-pore rate is not specified and must be verified against target flow and pressure conditions, requiring pre-order validation to ensure application fit.
