Overview
The SMC AFF-EL22B is a coalescing filter element designed for the AFF22 main line filter housing. This replacement cartridge removes water, oil vapor and other contaminants down to 5 microns, protecting downstream equipment and extending filter life in compressed air systems. The element features a modular design compatible with SMC’s air preparation product line.
Key Features
- Maximum operating pressure: 145 PSI (1.0 MPa); minimum operating pressure: 7.25 PSI (0.05 MPa)
- Approximately 1.3 times increased capacity over old AF models
- Operates at 41°F (5°C) to 140°F (60°C)
- Removes impurities such as oil, water and foreign matter in compressed air and improves the function of a dryer in the downstream
- Coalescing cartridge—easy slide-in, slide-out replacement design
- Lasts approximately 2 years depending on conditions
