316L Sintered Filter Plate 30μm Ø50×5mm 110 PPI ATOMFAIR®

316L Stainless Steel Powder-Sintered Filter Plate, 30 µm Filtration Rating, Ø50 × 5 mm, 110 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 110 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 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 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 installed with gradual pressure increase to avoid structural damage. Cleaning should be performed using validated backblowing, backwashing, or chemical methods when filtration efficiency drops below 50%.

Mechanical Integrity: Avoid impact, scratching, or concentrated tool pressure on the porous surface to prevent damage.
Pressure Handling: Increase pressure gradually during operation to maintain structural stability.
Temperature Limit: Do not exceed the normal use temperature of 500 °C to avoid material degradation.
Pressure Limit: Maintain working pressure at or below 3 MPa to prevent rupture or deformation.
Cleaning Protocol: Select physical or chemical cleaning methods based on the retained material and process medium compatibility.

HowTo

Install the filter plate with correct flow direction and gradually increase pressure to ensure proper seating. Monitor filtration efficiency and clean the plate using validated procedures when efficiency falls below 50%.

Required Equipment: Backblowing system, Backwashing system, Ultrasonic cleaner

Inspect the filter plate
Inspect the filter plate for visible damage, deformations, or surface contamination before installation.
Install with correct flow direction
Install the filter plate in the housing with the flow direction from the outside surface toward the clean side.
Gradually increase pressure
Gradually increase the working pressure to the target level while monitoring the flow rate.
Monitor filtration efficiency
Monitor filtration efficiency regularly and initiate a cleaning procedure if it falls below 50%.
Backwash or backblow the filter plate
Backwash or backblow the filter plate using a validated procedure to restore permeability.
Select appropriate cleaning method
Select physical or chemical cleaning according to the retained material and process medium, using compatible options such as ultrasonic cleaning, dilute acid, or alkali.

FAQ

What is the maximum working pressure and temperature for the 316L powder-sintered filter plate with 30 µm filtration rating?

The maximum working pressure is ≤3 MPa, and the normal use temperature is ≤500 °C. These limits apply to the Ø50 × 5 mm, 110 PPI plate in 316L stainless steel, as stated in the technical specifications. Operating beyond these parameters may compromise the sintered porous structure and filtration integrity.

Can this 30 µm sintered filter plate be cleaned and reused, and what cleaning methods are compatible?

Yes, the powder-sintered metallic media is designed for repeat use and can be regenerated using backblowing, backwashing, ultrasonic cleaning, or chemical cleaning with 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 or rapid pressurization must be avoided to maintain performance.

What are the key dimensional and structural specifications of the 110 PPI filter plate that affect integration into a filtration assembly?

The plate has a diameter of Ø50 mm and a thickness of 5 mm, with a nominal pore spacing of 0.23 mm, porosity of 30–45%, and bulk density of 4.4–5.6 g/cm³. The 110 PPI porous structure provides uniform interconnected flow-through pores, and the self-supporting 316L construction can be welded, bonded, or mechanically integrated. These parameters must be confirmed against the required flow, working pressure, temperature, and media compatibility before ordering.

Assessment

This 316L stainless steel powder-sintered filter plate offers a 30 µm filtration rating in a 110 PPI porous structure with Ø50×5 mm dimensions, providing rigid self-supporting construction suitable for cleanable, reusable filtration in pharmaceutical, chemical, and gas purification applications, though it requires careful handling and validated cleaning procedures to maintain performance.

Positive

Rigid metal construction with weldability and cleanability: The self-supporting 316L construction can be welded, bonded, or mechanically integrated, and the porous medium supports repeated use via backblowing, backwashing, ultrasonic cleaning, or chemical cleaning procedures.
High-temperature and pressure tolerance: Rated for normal use up to 500 °C and a maximum working pressure of 3 MPa, enabling deployment in elevated-temperature process streams and pressurized filtration assemblies.

Trade-offs

Fragile porous surface requires careful handling: The sintered porous structure can be damaged by impact, scratching, concentrated tool pressure, and rapid pressurization, necessitating gradual pressure increase and careful handling during cleaning and integration.
Requires validated cleaning procedures to maintain performance: When filtration efficiency falls below 50%, a validated backblowing or backwashing procedure must be used; incompatible cleaning chemicals can damage the media, and physical abuse must be avoided.
