So I finally got around to hooking up a filter/water separator to my air compressor setup, in addition to a second regulator to have more accurate pressure control closer to the actual hose (the one that came with the compressor itself is garbage). So far so good, it works very well. I'm running a 1/2" size SMC filter/water separator, Bellofram T70 regulator, and a SS Wika liquid filled gauge. A little overkill for the home shop, but I figured I wouldn't ever have to replace this setup again (except maybe the filter/water separator).
Anyways, since this is my first time formally setting up a filter & regulator for air lines, I wanted to check and see if there was a minimum distance of straight pipe/hose coming into and out of the setup? The reason why I ask is that I'm planning on adding some 90 degree elbows to help manage the lines (1/2" lines aren't the most flexible), and I'm concerned that if the 90 degree elbow is too close it will keep the flow & pressure from being at optimum levels (maybe it would cause the regulator to malfunction?). I'm thinking of adding a few inches of straight brass piping on the inlet and outlet side of setup, to alleviate any potential problems.
What does the have say?
Also, pics from right after I put it together. The red hose is 50ft of Goodyear 1/2" size, on a Lisle reel. The reel will be getting replaced before winter hits, its starting to leak and the 1/4" connection is restricting flow and hampering performance anyways.
