Bubble Point Test for Sintered Metal Filters

At CMI Filtration, quality is not just a promise—it is a measurable standard.
The Bubble Point Test is a non-destructive integrity test used to verify the pore size and quality of our filter media. By wetting the filter medium with a compatible liquid and gradually increasing air pressure, we can identify the largest pore size and ensure there are no defects or bypasses in the filter structure.
Why does this matter for your operations?
• Leak Prevention: It guarantees that your filter is structurally sound and free from microscopic manufacturing defects.
• Performance Reliability: Ensures that the filter will perform exactly as specified in your process flow.
• Safety Assurance: Provides peace of mind for high-pressure or critical chemical applications.
