Sintered Metal Pleated Filter

Sintered Metal Pleated Filter

High Surface Area Filtration for High Flow and Compact System Design

CMI sintered metal pleated filters are high-efficiency filtration elements manufactured by pleating multi-layer sintered metal mesh or sintered metal fiber media.

The pleated structure significantly increases the effective filtration surface area, allowing higher flow rates, lower pressure drop, and longer service life compared to conventional cylindrical filter elements.

By increasing filtration area within the same volume, pleated filters enable the use of smaller housings, reducing equipment footprint and overall system cost.

The filter media is bonded through high-temperature vacuum sintering, ensuring excellent mechanical strength, thermal resistance, and long-term stability under high pressure, high temperature, and high-viscosity conditions.

Why Pleated Design Matters

• A pleated element provides significantly higher filtration area than a standard cylindrical element
• Larger area enables higher flow capacity
• Higher flow allows smaller filter housings
• Smaller housings reduce system size and cost
• Lower pressure drop reduces energy consumption
• Extended service life reduces maintenance frequency

These advantages make pleated metal filters one of the most widely used configurations in industrial filtration systems.
