The legacy AFF series is an excellent first stage in an air purification scheme.  This coarse (3 μm) filter removes foreign matter and droplets to protect downstream dryers and extend the life of more precise filters.  Units are easily serviced, and dirty elements can be disposed of while handling only the filter bowl.

The AFF70~90 improves upon the performance of the legacy AFF with a 1 μm particulate rating and water removal capabilities.  Installation space is reduced by integrating the traditional AFF filtering function with the water removal capabilities of the AMG.  Additionally, flow capacities are improved for greater applicability.  A lightweight stainless steel bowl assembly improves handling and…

The AFF*-D main line filters are designed for modular connectability and to match the aesthetics of the AC-D series of FRL components.  Flow capabilities are improved beyond the legacy AFF series for extended applicability.  These particulate filters are nominally rated at 1 micron as an initial stage of cleanliness in an air purification system.
