Bag Filter Skid

Bag Filter Skid Systems

Pre-Assembled, Skid-Mounted Multi-Bag Filtration Solutions

CMI Bag Filter Skid Systems are fully engineered, skid-mounted filtration solutions designed to simplify on-site installation and commissioning of large-capacity bag filtration systems.

Instead of supplying individual bag filter housings, CMI delivers complete filtration skids integrating multi-bag filter vessels, interconnecting piping, valves, drip trays, and structural frames, all pre-assembled and tested before shipment.

At site, customers only need to connect the inlet and outlet pipelines, significantly reducing installation time, labor cost, and commissioning risk.

System Configuration Flexibility

CMI bag filter skids can be configured to meet a wide range of flow rates and redundancy requirements, including:

• 2 × 4 bag filter systems
• 2 × 6 bag filter systems
• 2 × 8 bag filter systems
• 4 × 6 bag filter systems
• Custom configurations based on project requirements

Both parallel operation and duty/standby arrangements are available to ensure continuous operation during bag replacement.
