316L Sintered Filter Plate 30μm Ø30×3mm 110 PPI ATOMFAIR®

316L Stainless Steel Powder-Sintered Filter Plate, 30 µm Filtration Rating, Ø30 × 3 mm, 110 PPI, 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 110 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 110 PPI porous structure has 0.23 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 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.

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.

Manufacturer: Atomfair LLC

Brand: ATOMFAIR®

Operate the plate only within its stated thermal and pressure limits and with process media compatible with 316L stainless steel. Use only compatible physical or chemical regeneration methods and avoid impact, scratching, concentrated tool pressure, and rapid pressurization.

Pressure and temperature limits: Increase system pressure gradually and confirm operating conditions remain within the stated normal-use temperature and maximum working pressure limits.
Media compatibility: Confirm compatibility of the process medium and cleaning chemicals with 316L stainless steel before service.
Filtration efficiency monitoring: Monitor filtration efficiency and initiate a validated regeneration procedure if it falls below 50%.
Surface handling: Avoid impact, scratching, concentrated tool pressure, and rapid pressurization when handling, installing, or cleaning the porous surface.
Cleaning options: Select physical or chemical cleaning according to the retained material and process medium, using clean-fluid backwashing, clean-gas backblowing, ultrasonic cleaning, dilute acid, dilute alkali, oxidizing agents, surfactants, or enzymes as appropriate.

HowTo

Install the plate in a compatible filter assembly with flow from the outside surface toward the clean side, then increase pressure gradually. Monitor filtration efficiency and perform a validated regeneration procedure when performance declines.

Required Equipment: Clean-gas supply, Clean-liquid supply, Ultrasonic cleaner, Compatible chemical cleaning agents

Inspect the plate
Inspect the sintered plate for surface damage, deformation, or contamination before installation.
Install the plate
Place the plate in the filter housing with the flow direction from the outside surface toward the clean side.
Pressurize gradually
Increase system pressure gradually until the operating pressure is reached.
Monitor efficiency
Monitor filtration efficiency during service and initiate regeneration if it falls below 50%.
Backwash or backblow
Backwash or backblow the medium with clean fluid or clean gas to dislodge retained particles.
Clean the medium
Clean the plate with an ultrasonic bath or compatible chemical cleaning agents selected for the retained material.
Verify before reuse
Rinse and verify performance before returning the plate to service.

FAQ

What is the maximum working pressure and temperature for the 316L powder-sintered filter plate with 30 µm 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 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 the porous body supports repeat use when surface damage, rapid pressurization, and incompatible cleaning chemicals are avoided.

What is the relationship between the 110 PPI pore density and the 30 µm filtration rating on this filter plate?

The 110 PPI porous structure has a nominal pore spacing of 0.23 mm and porosity of 30–45%, while the 30 µm filtration rating defines the particle retention size. These parameters are independently specified: the PPI describes the pore count per inch and spacing, whereas the filtration rating indicates the particle size retained. The product combines both to support precise selection for particle-removal tasks with low initial resistance.

Assessment

This 316L powder-sintered filter plate delivers a 30 µm filtration rating within a 110 PPI porous structure, offering uniform pores and low initial resistance for gas or liquid filtration in compact assemblies. Its rigid, self-supporting construction supports welding and mechanical integration, while cleanable porous media enables reuse, but users must verify operating conditions and handle the porous surface carefully.

Positive

Precise filtration with low resistance: Combines a 30 µm filtration rating with a 110 PPI porous structure (0.23 mm pore spacing, 30–45% porosity) for stable particle retention while maintaining low initial resistance across the plate.
Rigid, cleanable 316L construction: Self-supporting powder-sintered 316L plate can be welded, bonded, or mechanically integrated and regenerated via backblowing, backwashing, ultrasonic cleaning, or suitable chemical cleaning.

Trade-offs

Verify operating conditions before use: Flow, working pressure, temperature, and media compatibility must be confirmed prior to ordering; through-pore rate is not specified and depends on flow and pressure conditions.
Careful operation and cleaning required: Avoid impact, scratching, or concentrated tool pressure on the porous surface; if filtration efficiency falls below 50%, use validated backblowing or backwashing and avoid incompatible cleaning chemicals.
