New Compressor, questions

[Frozenstate]

I just purchased the Ingersol Rand T-30 compressor.
I am wondering what to set the cut in and cut out pressure. It will pump up, so far to 165 PSI, no problem.
I am going to mainly be running 1/2" impact, a DA sander , and filling tires, and hopefully a paint gun.. Do I need any kind of regulator? Should I get a water separator or any other kind of filter?

I would install a pressure regulator and a supply line water separator.

Years ago had a furniture stripping business which used quite a few pneumatic powered tools. Currently have a plasma cutter. Both systems with a water separator. You will be surprised at the amount of moisture the water separators catch.

Just for consideration, if you plumb this unit into your shop, you could add some in-line oilers for the lines which will run air tools. Most air tools will tell you the maximum pressure in their owner's manual, don't exceed that or you will shorten their life. So a regulator somewhere in the lines is a necessity. And if painting, for sure a water separator and filtration is needed. Most painting is done at much lower pressure than your unit is capable of (40-80 psi), so again, a regulator would be needed. How you do all this depends on whether you will use only the one pressure line, or will hard-pipe some lines in to your shop.

You want the regulator. The idea is to store lots of air (high pressure) but deliver it at the pressure the tools require. It seems most consumer grade air tools call for 100PSI max. Also the water separator.

You also need to drain the water from the tank fairly regularly.

I agree with everyone above. You will need a regulator and some sort of moisture trap. The moisture trap should be located some distance away from the compressor, maybe 15 or 20 feet.

If you do install an in-line oiler, do not use this line for your paint gun. That line would only be used for pneumatic tools that require oil.
I typically oil my tools by hand after use.

As far as the on-off pressures are concerned, I would think they were factory set. Turn on should be 145# or so and it should shut off at 175#.

Son and I installed commercial electricity in the acreage shop last fall and then plumbed in the air compressor.

The plumbing lines were installed in the rafters with drops near each large door and a hose reel near the center of the shop. We also put a drip leg with valve on the bottom of the copper line running up the 12 feet wall near the compressor.
