Poral, operating as part of ECM Components SAS (a subsidiary of the Grenoble-based thermal engineering group ECM Group), is France’s pioneer and leading manufacturer of porous sintered metal elements. Tracing its industrial roots back to 1945, Poral specializes in powder metallurgy techniques to manufacture porous metallic media for demanding industrial filtration, fluid flow regulation, and noise attenuation applications.

Based at its manufacturing facility in Le Pont-de-Claix in the Isère department, Poral fabricates its components in France using European-sourced metal powders. The brand serves more than 1,000 industrial customers worldwide, exporting over 30% of its production across Europe, the Americas, and Asia.

Poral provides specialized engineered components for harsh industrial environments, with applications spanning chemical synthesis, oil and gas, nuclear power, pharmaceutical process equipment, aerospace actuation, and industrial pneumatics.

Offer

Poral designs and manufactures porous sintered elements and assemblies in customized geometries and standardized configurations across multiple filtration efficiency grades.

Core Processes: Uniaxial pressing, isostatic pressing, and furnace sintering of spherical and irregular metal powders to create controlled interconnected porous structures with consistent permeability.
Materials: Sintered Bronze (suitable for operating temperatures up to 250°C in oxidizing atmospheres and 300°C in reducing atmospheres), Sintered Stainless Steels (AISI 316L, AISI 304L), and Nickel-based superalloys (including Inconel).
Filtration Performance: 8 to 9 standard Poral grades (from Grade 03 to Grade 60); 98% retention of solid particles from 0.2 µm to 13 µm in gases, and from 3.2 µm to 190 µm in liquids.
Product Geometries: Sintered cartridges (DOE standard), multi-cartridge filters, seamless and welded tubes, porous disc filters, plate filters, cone filters, candle filters with threaded connections (M20x1.5, BSP, NPT), and pneumatic silencers.
Assembly & Regeneration: In-house precision TIG and laser welding of porous media to machined end-caps and flanges; filters are cleanable and regenerable via ultrasonic, backflush, chemical, or thermal treatment.
Applications: Liquid and gas filtration, sparging/gas bubbling, powder fluidization, noise attenuation, flame arresters, vacuum lifting pads, and flow restrictors.
