Overview
The SMC AFF-EL22B filter element is a modular coalescing filter cartridge engineered for main-line air filtration in compressed air systems. As part of SMC’s AFF series, this element delivers reliable water separation and contamination removal in industrial automation, pneumatic control, and production environments where clean, dry air is critical to equipment longevity and performance.
Key Features
- Coalescing filter removes water droplets, oil vapor, and solid contaminants down to 5 microns
- 1.3× increased capacity over legacy AF-series elements
- Improved water separation efficiency extends service life
- Modular design integrates with other SMC air preparation equipment
- Replaceable cartridge design enables quick maintenance without tool changes
- Typical service life approximately 2 years depending on system conditions
