SOURCE: need to know how to adjust pressure regulator for low/high limits

sorry to be contradictory here, but better not to mislead or scare someone... Thepressure relief valve has absolutly nothing to do with cut in cut out pressure settings.the pressure relief valve is abrass fitting on the outside of the tank hexagonal fitting with a thin shaft coming out of the centre normaly with a ring on it not unlike akey ring .THAT is a blow off valve a safety device, that long before the air pressure is too great for the tank,will blow offthe air pressure in the tank ,try it, grab the ring and pull it out and it will dis charge any air in the tank ,that ios what it will do if thair is too great in the tank.. tanks are pressure tested and the appropriate valve fitted. NOW FOR YOUR ORIGINAL PROBLEM .you will find a control box ,useualy black or dark brown bakerlite cover,the electric cord goes into it ,also there will be another electric cord coming out and going to the electric motor that drives the compressor . If you take the cover off this you will find the cut in and cut out adjustments that allow you to set the cut in and cut out pressure as high or low as you want,that is whith in the capascity of the unit.It is self explanitory and there will be ( or should be ) instructions inside the cover .If you have any difficulty come back to me preferably with themotor and compressor sizes and i will walk you through it NOW AS MUCH AS THIS GOES AGAINST THE GRAIN, SHAG79 IT WOULD BE FAR BETTER IF YOU KNEW A BIT MORE ABOUT THE THINGS YOU ARE ADVISING THEM ABOUT EXPLOSIONS AND DEATH !!! WHAT ARE YOU-----A ******???

SOURCE: ingersoll rand compressor T30 model 7100

I would wonder A if the wiring was heavey enough to carry that sort of load with out overheating B if the motor is big enough to do it for the same reason( ?what is the duty cycle?) C if the receiver is big enough to allow reasonable time between shut down and start up --- remembering that at start up the motor pulls double the current to start up and if it doesn `thave sufficient time to cool alittle before being called on to do it again and that would prompt the question ,does it have sufficient ventilation? these are all queries that would need addressing before I would try to offer a solution ,one thing is certain ,--there is something wrong

SOURCE: what type of oil for ingersoll rand model 2475 air

Ingersoll Rand likes you to buy their all season select oil for their air compressors, most piston air compressors use an R+O 100 oil it is equivalent to n SAE 30 wt oil.

SOURCE: I have an Ingersoll Rand

When the compressor comes up to pressure and kicks off, you should normally hear a gasp of air escaping. That gasp is the release of pressure from the compressor itself - not the tank, and it is supposed to get released so that the compressor can restart without being preloaded with compressed air. My guess is that the gasp is not happening. It is probably some debris or a gummy mechanism. The mechanism is supposed to be triggered by the same mechanism that shuts off the motor.

SOURCE: How do I adjust shut off pressure on an Ingersoll

The best way to go about the task of adjusting the pressure switch is to remove the cover to switch and note the brand/model number. Sometimes instruction are under cover of switch. With switch information, look for mfg. instructions. You will most likely see one or two springs with lock nuts. Do not turn them yet. Most pressure switches are sold with factory adjustment and are sold in pressure ranges. For two stage compressors as yours, the pressure is usually factory set at much higher (150-175) pressures than single stage which is usually about 120 -125. If you change the pressure setting it will also change the differential cut on pressure. The factory will actually use different springs to achieve desired pressures and are color coded. There are too many different brands of switches to recommend how to change pressure setting. You may discover that you can only change the pressure just a small amount (+or -15-20psi ). If you find the information about your switch, make sure that you count the turns exactly so that you can return to factory settings if things go wrong. You can extend the life of the comperssor by lowering the pressure as more amperage /heat is produced to achieve higher pressures. Good luck

WHY DOES A SM75 INGERSOLL RAND COMPRESSOR CUT OUT ON LOW PRESSURE OIL


Low oil pressure. Are you adding a lot of oil. Have you check the oil level. Switch could also be bad.

WILL T21 SELECT OIL WORK IN A MODEL 2475


The solution was easier than I expected. Ingersoll Rand "Select" oil is a synthetic oil recommended by Ingersoll as better than mineral oil. T30 (mdl 2475) and T21 are different styles of compressors. So, yes "select" oil can be used in the Model 2475 compressor.

What weight of lubrication do i use for this compressor...Ingersoll Rand TS4N5? And do I need to bleed the tank off before adding oil?


Yes it is always a good practice to bleed the tank down. there is a check valve in the top of the receiver tank that keeps air from blowing back Thur the system. However if it's leaking you will have pressure on the oil sump. As for type of oil use a 30 weight non detergent oil. Recommend using ir's t30 all season or another type made for air compressor's.
