SMC AFF-EL11B Air Filter

The AFF-EL11B is a 3 μm replacement filter element for SMC’s AFF11C main-line compressed-air filter (size 11), designed to install in AFF11C housings and restore filtration performance when the filter media has become saturated or clogged. It provides 3 μm filtration with ≥99% removal of oil, water droplets, and solid particles from the compressed-air stream, helping protect downstream dryers, precision filtration stages, and pneumatic components in industrial air lines. As part of the AFF Series Main Line Filter family, which spans sizes 2 through 22, the AFF-EL11B is the replaceable element used for the size-11 module in these high-flow filtration systems. Typical applications include manufacturing and automation environments where clean, dry compressed air is essential for sensors, actuators, pneumatic cylinders, and other equipment, enabling more reliable operation and reducing contamination risk in downstream equipment. The element is designed for replacement within AFF11C assemblies and is part of a broad AFF filtration lineup employed in many industries.
