Sintered Metal Fiber Pleated Cartridge

Sintered Metal Fiber Pleated Cartridge

High-Temperature Pleated Metal Filter for Flue Gas and Industrial Dust Removal

CMI sintered metal fiber pleated cartridges are high-performance filtration elements manufactured from stainless steel sintered metal fiber felt with a pleated structure and internal support core.

The pleated design significantly increases filtration surface area, enabling high flow capacity with low pressure drop, while the metal fiber media provides excellent temperature resistance, durability, and stable filtration performance under harsh conditions.

These cartridges are widely used in high-temperature flue gas filtration, industrial dust collection, and powder recovery systems, where conventional polymer filter cartridges are not suitable.

They serve as a durable alternative to polyester or cellulose-based cartridges and can be used as replacement elements for international brands in demanding industrial applications.
