Klutch Air Compressor Filter–Regulator–Lubricator Combo, 1/2in., 106 CFM

Works great. I use this with my brad nailers, framing nailer, stapler. I bought this when I upgraded my compressor. I previously had a cheap, inline filter and lubricator. I regulated pressure at the compressor, which was a pain. Now I can easily regulate, check the filter, and check pressure. Compared to similarly priced FRLs, the quality of materials on this is superior. Though a FRL shouldn't take any abuse anyway, I always tend toward things that are over-built.

This regulator and filter set-up seems to be high quality, especially for the price. It is 1/2 NPT which is what I needed and having a filter and oil cannister with a regulator is a good value. The regulator took a little getting used to at first but it works fine and seems to hold the pressure pretty well. You can't really go wrong for this price because this is made from mostly cast aluminum and other much more expensive units have more plastic parts.
