Hello all, I'm replacing the broken gauge on the regulator and the one I'm replacing it with is 1/2" npt instead of the 1/4" npt gauge that is oem. I'm hoping it's just a matter of a reducer, but can I still expect a correct reading using the reducer? Thanks, Tom

General air compressor question....

.......when increasing the air hose size I could expect a drop in pressure because of the increased volume, ......... Tom
increasing hose size will not decrease pressure . a larger hose has less friction loss, thus more volume flow therefore more pressure when using the tool or whatever you're using.
I don't mean to hijack the thread, but I've always wondered...when I was picking up some air filters, I noticed the 1/2", 3/8" and 1/4" sizes could all handle quite a bit of PSI and CFM. When connecting to a 20 gal compressor would you lose anything going for any of those sizes?
I know the 1/2" is probably preferred but the 1/4" flow specs were well past what this compressor could put out it seemed? (It's a Speedaire 20 gal oiled unit, so not some piece of junk)

Larryg you just size the air filter to your air lines, whose inside diameter is determined by the length of the run and air consumption needs of the tools you will be using .
a 1/4" filter may flow 50 cfm but that's not telling you you are going to get 50 cfm at the end of a 100ft 1/4" hose after the filter.
i hope that makes sense, I'm sleepy

When buying a coalescing filter, it's best to choose the smallest filter that meets the CFM requirement. The filter works in part as an inertial trap. That is, incoming air and water is separated by the much higher inertia of the water as the mixture swirls in the separator.
Using a larger separator than required reduces the swirling action within the separator and reduces it's effectiveness.
Norgren publishes both a minimum and maximum flow on many of their separator products.
