Customer Cases

1. Product Concept

The CM-33-5 is a high-performance multi-stage combination filter cartridge designed for advanced compressed air purification. It integrates dual-stage filtration technology within a standard 5-inch format: first-stage coalescing removes liquid aerosols and solid particulates, while the second-stage activated carbon bed eliminates oil vapors and odors. This integrated design provides comprehensive protection exceeding standard coalescing filters, targeting both visible and gaseous contaminants to achieve true oil-free air quality (≤0.01 mg/m³ oil content) as defined by ISO 8573-1 Class 1 standards.

2. Key Features & Advantages

Integrated Dual-Stage Technology

• Primary Stage: High-efficiency borosilicate glass fiber media captures 0.01 µm oil/water droplets (>99.5% efficiency)

• Secondary Stage: Impregnated activated carbon bed adsorbs oil vapors, hydrocarbons, and odors

• Unified Construction: Stabilized media layers prevent channeling, ensuring sequential filtration

Superior Performance Characteristics

• Air Quality: Consistently delivers ISO 8573-1:2010 Class 0/Class 1 air for oil content

• High Capacity: 40% larger adsorption surface area than standard 5-inch vapor filters

• Energy Efficient: Optimized pleat geometry maintains <0.07 bar initial pressure drop at rated flow

• Temperature Resilience: Functions effectively across 4-60°C operational range

Operational & Economic Benefits

• Extended Service Life: 2-3× longer change intervals compared to separate coalescing+vapor filters

• Reduced Maintenance: Single cartridge replacement vs. multiple element changes

• Space Optimization: Combines two filtration stages in one housing footprint

• Cost Efficiency: 30% lower total ownership cost over 3-year operational cycle
