I have a 7.5 hp ingersoll rand. 230/3/60 . I need a cut in pressure of 85 and a cut out pressure of 125. Will this work. What is the pressure difffere

this switch has a cut in of 135 and cut out of 175. 85/125 sure seems low for a 7.5hp compressor. If you need lower pressure purchase a regulator and regulate pressure down.

yes. tighten the adjustment for higher cut out pressure. let the cut in pressure fall where it may.

I don't think so because you apparently have three phase power, this switch only has two wire break capacity.

The weight is not the same. You can use you regular gauges. Just what cross contaminating mineral and synthetic oil. The low side pressure should be the same. But the high side should be lower, because it is more efficient. The should be a conversion chart supplied or on the various websites. It works well.

Works great. Let me know which engine your running and I will tell you which pressure regulator to install ahead of it. You need a large micron pre filter ( 30 micron is great) and a 10 to 20 micron between pump and rail. Keep the inlet side 3/8 to keep from restricting pump. That's the mistake people make and burn the pump up from starvation. Good luck with your project .

I'm sorry...not sure. Normal shop air pressure is about 150-175lbs. Don't recall what input pressure spec. Is on the regulator.

My air pressure is set at around 100psi.I don't think I had to change any settings between sizes!Another thing to consider---I NEVER had any luck using one of those pancake compressors---you gotta go back to the old-fashioned motor belt driven compressors.

This switch is adjustable. You can set the cut-in and cut-out pressures separately. It's set at the factory for 40/60, but you can make adjustments internally to lower (and I think higher) pressures, e.g., 30/50. (Note: I haven't done this and I don't work for the company and accept no liability.) The Square D web site is not very helpful, but the web site for Pumptrol (the Square D pressure switch brand) has a lot of info. If you look up the 9013 series of pressure switches, you'll probably find the info you're looking for.

I have no idea, I'd call Rheem Tech support. They were very helpful during my install. Personally, I don't think pressure variations would be an issue, but who am I to know?

The manual requires 80 - 100 psi. I am running this on a large compressor, but I see no reason why the tank you are looking at wouldn't work. My BOSTITCH PN50 Mini Impact Nailer can drive a 3-1/2" hot dipped deck framing nail into a 6"x6" post in less than 2 seconds. Don't know how I got along without it.

Sorry, I really don't know. Pressure is pressure and I would assume it would.

I'am on 220 also, pressure at 63 psi at 30amp it should cut nice and easy, make sure you got the right set up in your gun, I keep about 1/16 inch from surface.

I'm using it on a 55. That reads nearly 2000 psi on the tank side, and is adjustable on the output side. I'll note that if you need it to be a pressure under 50psi on the output, it may take a little adjusting to get just right.

I would not worry. 400 or 600 you will not need that high of pressure under normal use. My guess would be if the gauge says 600 then its 600

The literature for your 1 pint or 1/2 pint vessel should describe the exact size of charger to use. I don't think there is a universal answer to your question. Frankly, I suspect that because of the reduced size (0.5L or 0.25L) might result in too much pressure. If you no longer have the literature that came with your vessel(s), you might be able to find it or the information you see by googling or dogpiling your vessel name. I hope this is somewhat helpful.

Cut in pressure is the longer of the two adjustments, centered on the switch. In for higher cut in, out for lower. Cut out pressure is the shorter of the two located to one side. Again in (clockwise) for higher out for lower. I suggest you check both and the air pressure in your tank with the tank drained, mine needed to be just slightly lower than switch cut in pressure. Hope this helps.

Greetings: ST200M75 is a different size and pressure. We will have this listed on Amazon for the weekend under number ST200M75 . Thank You, Lou Fishman

They sell one with an output of 3000psi!!! Also, adding shims raises pressure, and it is simple. You just need an allen wrench. Make sure to empty the tank first.

This pressure switch is pre-set at 30-50 psi. If the cut-off or cut-on pressure needs to be changed, turn the larger spring nut clockwise to increase the cut-off and cut-on pressure. The rate of increase is 2 1/2 PSI for every complete turn of the nut. This adjustments maintain a 20 PSI differential between cut-on and cut-off pressures, which is best for pressure tank performance. Do not adjust the small spring which changes the cut-off pressure (to raise, turn clockwise). Never adjust cut-on below 20 psi or cut-off above 60 psi.
