Overview
The SMC AFF-EL22B air filter element is a coalescing filter cartridge engineered for compressed air cleaning in industrial pneumatic applications. This replacement element fits directly into SMC AFF22 filter housings and provides superior contamination control by removing water, oil vapor, and particulates down to 5 microns, protecting downstream dryers, regulators, and control equipment.
Key Features
- Coalescing design removes water, oil vapor, and contaminants down to 5 microns
- Increased capacity (approximately 1.3× versus older AF series models)
- Typical service life of approximately 2 years depending on air quality and usage conditions
- Direct replacement for AFF22 filter housings—slide-in installation
- Complies with ANSI/CAGI ADF 400-1999 and ISO 8573-4 compressed air standards
- Improves downstream dryer efficiency and extends precision filter service life
