316L Stainless Steel Filter Plate 10µm Ø100×25 mm ATOMFAIR®

316L Stainless Steel Powder-Sintered Filter Plate, 10 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 10 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 10 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.

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.

FAQ

What is the maximum working pressure and temperature for the 316L powder-sintered filter plate with 10 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 with 30–45% porosity and 4.4–5.6 g/cm³ bulk density, as specified in the technical specifications.

Can this Ø100 × 25 mm sintered filter plate be cleaned and reused, and what methods are recommended?

Yes, the metallic porous body is designed for repeat use and can be regenerated using backblowing, backwashing, ultrasonic cleaning, or suitable chemical-cleaning procedures such as dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes. The cleaning method should be selected based on the retained material and process medium, and surface damage, rapid pressurization, and incompatible chemicals must be avoided.

What are the key compatibility constraints when integrating this 40 PPI filter plate into a filtration assembly?

The filter plate requires confirmation of flow, working pressure, temperature, media compatibility, through-pore requirement, and dimensional tolerance before ordering. It is a self-supporting 316L component that can be welded, bonded, or mechanically integrated, but the flow direction is normally from the outside surface toward the clean side. The 10 µm filtration rating and 0.64 mm nominal pore spacing must match the target particle-removal task to avoid premature fouling or efficiency loss.

Assessment

This 316L stainless steel powder-sintered filter plate offers 10 µm filtration precision with a 40 PPI porous structure in a Ø100 × 25 mm disc format, providing a cleanable, reusable metallic medium suitable for elevated temperature (≤500 °C) and moderate pressure (≤3 MPa) applications. Its rigid construction allows integration via welding or bonding, but requires careful pressure ramping and validated cleaning procedures to maintain filtration efficiency.

Positive

10 µm filtration with 40 PPI porous structure: The 10 µm filtration rating combined with a 40 PPI porous structure (0.64 mm nominal pore spacing, 30–45% porosity) provides precise particle retention while maintaining stable gas or liquid passage with low initial resistance via interconnected flow paths.
Cleanable and reusable metallic construction: The powder-sintered 316L medium can be regenerated by backblowing, backwashing, ultrasonic cleaning, or compatible chemical cleaning, supporting repeated use and reducing replacement frequency.

Trade-offs

Requires careful pressure management: Pressure must be increased gradually; rapid pressurization or impact can damage the porous surface. Filtration efficiency below 50% necessitates a validated backblowing or backwashing procedure, and concentrated tool pressure on the porous surface must be avoided.
Infrastructure for cleaning regeneration: Effective cleaning requires selection of compatible physical or chemical methods (e.g., clean-fluid backwashing, ultrasonic, dilute acid/alkali, enzymes) based on the retained material, and validation of the procedure is needed to maintain performance without compromising the porous structure.
