Customer Cases

**1. Product Concept**

The CM-28SB-5 is a high-performance coalescing filter cartridge engineered for critical compressed air and gas purification. It represents an advanced filtration solution designed to remove sub-micron liquid aerosols, solid particulates, and moisture from compressed air systems. The product is built on the principle of maximum contaminant removal with minimal energy loss, integrating a precision-engineered multi-layer media structure within a robust mechanical design. Its core concept focuses on delivering **ISO 8573-1:2010 Class 1** air quality while optimizing total cost of ownership through extended service life and energy efficiency.

**2. Key Features & Advantages**

*   **UltraPleat™ High-Efficiency Design:** Incorporates a proprietary pleating technology that maximizes filtration surface area, ensuring **extremely low initial pressure drop** and sustained high flow capacity (as indicated by the "28" series designation). This results in significant energy savings over the filter's lifespan.

*   **Advanced Multi-Stage Media:** Constructed with graded-density glass fiber and synthetic layers that progressively capture and coalesce oil aerosols, water mist, and fine particles down to 0.01 µm, achieving **>99.99% removal efficiency**.

*   **Robust Construction & Reliability:** Features a corrosion-resistant metal core and end caps with dual silicone O-ring gaskets (suggested by "SB") to ensure a **positive, bypass-free seal**. This rigid structure prevents media migration and withstands pressure surges, guaranteeing consistent performance.

*   **Extended Service Life & Economic Efficiency:** The large contaminant-holding capacity and optimized media design dramatically extend change-out intervals, reducing maintenance frequency, downtime, and waste disposal costs—delivering a **lower total cost of ownership**.

**3. Application Fields**

The CM-28SB-5 is deployed in industries where compressed air purity directly impacts product quality, process safety, and operational reliability:

*   **Life Sciences & Food Processing:** Pharmaceutical manufacturing (GMP compliance), food/beverage packaging and filling (FDA-related requirements), and biotechnology fermentation processes.

*   **Precision Manufacturing:** Electronics and semiconductor production (chip fabrication, cleanroom environments), optical lens coating, and precision pneumatic instrumentation.

*   **Surface Treatment & Quality-Critical Processes:** Automotive and industrial spray painting (prevents fish-eye defects), powder coating systems, and critical air-driven tools.

*   **General Industrial Protection:** Instrument air systems in oil & gas plants, downstream of lubricated compressors in manufacturing facilities, and as point-of-use filters for sensitive equipment like CNC machines and robotics.
