Multi-Tube Sintered Metal Filter Assembly

Multi-Tube Sintered Metal Filter Assembly

High-Flow Sintered Filter Module for High-Temperature and Industrial Applications

CMI multi-tube sintered metal filter assemblies are modular filtration units composed of multiple sintered metal powder filter tubes integrated into a rigid welded structure.

This multi-tube design significantly increases filtration surface area and flow capacity, while maintaining excellent mechanical strength and structural stability under high temperature and pressure conditions.

Compared to single-tube filter elements, multi-tube assemblies provide higher throughput, lower pressure drop, and improved cleaning efficiency, making them suitable for continuous industrial processes.
