In my opinion formed from direct experience and having read the opinions
and experiences expressed by others - They over rated it, whored out
their name, and made it as cheaply as possible to maximize profits. If
they had put a 7.5 HP motor on it then it would actually do what it
claims and hold up okay. If they had put a smaller pulley on it and
settled for a lower CFM spec on the sales sheet it would have worked
probably just fine and lasted. They didn't do that and as long as they
have been in the business they should have know it was going to be a
lousy product. The thing is I keep getting better and better stuff for
my shop as I can afford to. Next time I upgrade my shop compressor I
won't "step up" to any "better" product from Ingersol Rand. I will buy something else. Anything else. Based on my direct experience its my
opinion that Ingersol Rand can not be trusted.

I just received a call from somebody at Ingersol Rand. I may not have
the details down 100%, but this is the gist of it.

"Everything about "that compressor" was specified by the customer right
down to the belts we had to use. We have discontinued our relationship
with that customer/vendor due to the damage it was doing to our
reputation."

You know it's funny. I had an email just this morning from somebody who
wanted 30 different molds made. Pretty decent size job. Each one would
have had to been worked up from scratch, so it would have been a nice
chunk of cash all at once with all that seat time. I've had bigger runs
a few times, but not a bigger single job of all one off pieces. The job
had some things that violated my published policies, and I turned it
down. I could use a nice cash infusion a job like that would bring. I
admit I struggled with it for a minute, but I turned it down. Maybe
Ingersol Rand should have turned it down too.

It kinda sounds to me like they did whore their name out for money...
and now they are regretting it.

https://www.woodweb.com/knowledge_base/Running_Two_Compressors_Together.html

My two are a 1/2 HP 12 gallon roll-around and the 3.7HP 80 gallon upright.
By connecting the tank of the small one to the house air line I have the jobsite adjustability of the portable with the capacity of the large one.

The outdoor air connection is an inconspicuous water faucet, that takes a
GHT to NPT adapter to air hose. GHT is the official abbreviation for Garden Hose Thread, which can be hard to tell from 3/4" pipe thread without a
label. A 3/4" male PVC pipe plug screws into the female end of garden hose
well enough to keep bugs out.

I think I have three portable compressors. A baby one I only use for a
brad nailer. A pancake that was used as a pre load compressor for an
HPA compressor, and my roll around. They almost always sit around empty
and in the way.

Well, I do also have two or three HPA compressors, but I have no clue if
the gas motor on the old air force one still works.

There are plenty of examples of accountants or politicians over-ruling good engineering judgment and suffering for it later. The risk can't always be convincingly proven. The Challenger disaster is a good example, if not for politics the booster shells could have been made locally in one piece
instead of segments that were shippable from Utah.

I didn't mean to suggest a small portable as a solution, I assumed you could add another stationary compressor adequate for the increase in the demand, instead of all of it, and run both when necessary. I gave the 1/2 HP as an example of a severe mismatch that still works.

The pressure settings create switching logic that lets you control when one
or both are operating.

When I'm sandblasting the 1/2 HP compressor can't quite keep up, but the
pause to refill the gun's canister lets it catch up if connected to a large external tank so it runs continuously. Without the extra tank it pumps to shutoff and then turns on after I start again, without much reserve.

-------------------------------

In the 70's before industrial-type equipment scaled down and priced for home use became available I assembled my portable compressor from components, including a pressure switch meant for water well pumps. It appears to have separate screw adjustments for the pressure differential and the on/off setpoint, and they interact with each other. Do you know a good procedure to adjust the turn-on and turn-off pressures with this type of control?

If I'd had a second compressor I would have attached the control to its regulator to change the "tank" pressure without having to repeatedly bleed
and refill it. Or I could have moved the wiring to an enclosed manual switch box (hanging on the motor wires) and the control to the regulator output.

I reset the safety valve by shorting the motor to the line in the control
and shutting it off at 125PSI by pulling the plug. Reducing it allowed a
larger motor pulley and higher CFM without exceeding the nameplate current.

I have a water well pump with a similar switch, and I have never touched
it. Even when I replaced the well pump. However, unloader capable air pressure switches are readily available. I bought my last couple from
McMaster because I knew whatever brand it turned out to be it would be
quality. That might have been before I learned the brand and model of
products on McMaster is listed in the specifications if you look. Or
maybe I just didn't care.

If I'd had a second compressor I would have attached the control to its regulator to change the "tank" pressure without having to repeatedly
bleed and refill it. Or I could have moved the wiring to an enclosed
manual switch box (hanging on the motor wires) and the control to the regulator output.

If I had a second compressor pump for my shop air I'd use a sequential
timer. We did that with air conditioning compressors on our family
grocery store. Another alternative might be a regulator/check valve
between two tanks. They would never start at the same time that way.
One thing I also thought about was buying one of the big propane tanks
used for wind generators in the citrus orchards. It can certainly take
the pressure, already has a great safety valve, and I could plum
multiple pumps into it. The thing is I already have way to many
projects, and then of course SLJs take up a lot more time than you would
think too.

Like today. I have molds to cut. Molds that are done and need to ship,
and tracking shows the new shocks I ordered for the Jeep will arrive
sometime today. That's just today.

SLJ #1 - Busted Laundry Hamper - Yeah, its just as tedious as it sounds.
LOL. Its 32 minutes long and I cut out 90% of it already. LOL

I fixed the broken handle on a Rubbermaid Hip-hugger laundry basket by
bending conduit to fit under the rim.

I'm pretty sure my 200A service would handle two compressors starting simultaneously. In normal use they wouldn't if their cut-in and cut-out settings differed, unless the air leaked out while they were shut off.
Turning one and then the other on should separate the surges enough. For you the "3 wire control" contactor setup would keep them from automatically restarting after a power outage.
