Air compressor regulator help please

[Turbo1002]

Currently, when my impact aircat 1155 runs there is a 20psi drop at the gauge on the regulator. I have an 80 gallon 2 stage compressor with a old craftsman (16008) line filter going in to a (16022) regulator/filter. The 3/4 out of the tank is reduced to 3/8 which is the size of the regulator and filters. From there another reducer to 1/4 where a 3/8 50 foot air hose with a v-style fitting into the tool. I am guessing the regulator can not keep up with the flow. Can someone please help me choose a regulator and filter which has the flow capabilities for high volume air tools. I don't care if it is used, old or new. Just want something which works. BTW, it has to be able to handle 175 psi inlet.
Thank you.

I dunno how much you want to spend but there are a lot of high flow regulators out there. I was going to suggest checking the filter as well. What you have isn't really what I call a filter, but a moisture trap. Regardless, you'll want to replace that with a high flow version too

are you setting the regulator with the tool running and under load?

I think this might be the key here. I have the same kind of drop in pressure when I fire up my tools so I adjust the regulator higher so that when the tool is running, the gauge on the regulatorn reads 90 psi.

If that's not the way its supposed to be, I'm sure I'm about to hear aboubt it...

the correct way is to set the regulator with the tool being operated

Ordered a speedaire regulator, filter and lubricator. Kept the 3/8 size. Hope that does not bite me for not going 1/2''. Figured, the air hose is 3/8 what would be the need to go larger. The max flows are regulator 208 cfm, filter 56 cfm (5 micron) and lubricator 75cfm. Hope this does not put too much restriction. Thank you all for the help.

I would lose the lubricator. I find them more of a mess, plus once you get oil in that hose you cannot ever paint with it or use a blow gun on something you will paint because you will be blowing out fine particulars of oil.
