Porous Metal Cups
CMI Porous Metal Cups are high-performance filtration and flow control components manufactured using advanced powder sintering technologies. These cups feature a controlled and uniform pore size distribution, ensuring predictable filtration performance and consistent flow distribution across various media.
Engineered for durability, these components offer high mechanical strength and excellent corrosion resistance, even under extreme pressure and temperature conditions. With a filtration rating ranging from 0.3 to 100 μm and customizable dimensions (OD up to 450 mm), CMI cups can be produced from premium materials such as 316L Stainless Steel, Titanium, and Hastelloy. These cups are fully cleanable, back-flushable, and can be integrated with metallic or non-metallic fittings for complete, ready-to-install units. They are the ideal choice for critical applications including catalyst retention, HPLC inlet protection, and gas-liquid sparging in the pharmaceutical, chemical, and food & beverage industries.
CMI manufactures porous metal cups using advanced powder sintering and porous media technologies for demanding industrial filtration and flow control applications.
These components are engineered with controlled pore structures to ensure reliable filtration performance, consistent flow distribution, and excellent chemical compatibility across a wide range of industrial environments.
Dimensions, wall thickness, pore size, and material selection can all be customized during production to meet specific process requirements.
Porous metal cups can also be integrated with metallic or non-metallic fittings through welding or mechanical assembly, delivering complete ready-to-install filtration or flow control units.
