The AF-D series of modular air filters brings a modern appearance to SMC's line of filters while maintaining the high performance of our other series.  These 5 μm units can serve as appropriate filtration for many applications or as a pre-filter for fine filtration/coalescing units.  The transparent bowl guard on the size 30 and larger provides improved environmental protection as well as full view of the bowl contents.  The AF-D is currently available in three body sizes with more to come in the near future.
