Filtration Solutions for Automotive Manufacturing

Automotive manufacturing processes require stable and high-efficiency filtration to ensure product quality, process reliability, and equipment protection. CMI Filtration provides engineered filtration solutions tailored for key stages of automotive production, particularly in paint shop and water treatment systems.

Key Application Areas

Pretreatment & Washing Systems

In the pretreatment stage, filtration is critical for removing metal particles, oil residues, and suspended solids from process water. CMI solutions help maintain water cleanliness in degreasing, phosphating, and rinsing processes, reducing contamination and improving coating adhesion.

Paint Shop Circulation Systems

Automotive paint lines require consistent filtration to maintain coating quality and surface finish. Our filtration systems are used in circulating water loops, electrocoating (E-coat) systems, and topcoat applications to remove particles and prevent defects.

High-Precision Coating Filtration

For critical coating stages, high-efficiency filter bags and cartridges ensure removal of fine particles, enabling smooth and defect-free finishes in automotive painting processes.

Solution Capabilities

• Bag filter housings for large flow circulation systems
• High-efficiency filter bags (extended life and multi-layer structures)
• Cartridge filtration for fine and critical filtration stages
• Magnetic filtration for metal particle removal
• Skid-mounted filtration systems for integrated solutions

Benefits

• Improved coating quality and surface finish
• Reduced water consumption through recycling systems
• Lower maintenance and downtime
• Enhanced protection of downstream equipment
