Overview
The SMC AFF-EL4B is a replacement coalescing filter element for the SMC AFF4 series main line filter. It removes impurities such as oil, water vapor, and contaminants from compressed air systems. This replaceable element delivers reliable filtration in industrial and pneumatic applications, improving system uptime and protecting downstream equipment.
Key Features
- Coalescing filtration: Removes oil vapor, water, and contaminants down to 5 microns for clean compressed air
- Increased capacity: Approximately 1.3 times greater dirt-holding capacity than earlier AF models
- Easy maintenance: Slide-out, slide-in design for quick element replacement
- Extended service life: Improves water separation efficiency and typical service life of approximately 2 years
- Wide operating range: Functions reliably across diverse industrial environments
