Quick question.What air pressure do you guys run in your shops? I"ve got an old Wayne compressor that shuts off at 150 psi.Seems like the old girl is working her tail off to get up to that pressure.I just bought an ancient Kellogg-American compressor to use as a back-up.This one shuts off at 125 psi.Seems it just coasts to get up to pressure.I"ve always felt I needed that 150 psi.Maybe I really don"t.Could be that 125 would be enough??? I run a beadblast cabinet,various air tools,and an old air over hydraulic in-ground car lift. Any input?? Thanks in advance.

This lower pressure is fine but go inflate a 11r-24.5 truck tire to 110 psi or a 255-22.5 to the 120 psi at -10 degrees out and tell me about the lower psi . I'll keep the 175 or higher thankyou. That 135psi the compessor cuts out and won't cut in and the tire is still low so with the 175 it fills then the air wrench will cause the compessor to cycle.

When I was the maint. manager of a plant a few years ago our 25hp screw type compressor ran between 100-110 Psi for cycling the compressor. very efficient for a continuously running comp. 150 is too high IMO. Most industial pneumatic systems are designed to run at 60psi, I am talking about air valves and cylinders for automation.

I think but may be wrong that the 90 PSI rating is because of OSHA regulations. I do not think any manufacturing plant, if there is any left in the US, can run over 90 PSI. I have an OLD Whirthington 2 cylinder, 2 stage powered by a 6.5 HP gear driven Clinton. It will go to 175 PSI without a problem. It will sure wack-up my CP-734 impact.

Pete, 125 would be enough. The only thing to consider is the cut-in pressure. Once you drop the cut-off, the cut-in will drop too and you probably don't want it to drop below 90. You can adjust the differential screw on the pressure switch to cut in at 100, but now your machine will cycle too often. Find a happy medium, good luck.

Air tools are rated (@90)PSI and they will meet their rated power if they also have the volume which you cannot be obtained with 1/4 inch couplers.That is one reason that many use the higher psi to get the volume the tool needs.Higher power can often be obtained by enlarging the air outlet of the impact wrench but this shortens the life of the hammer mechanisim.

Is the Wayne compressor a two stage or single? Two stage has, generally, two cylinders of different sizes, the generally pump to 175 psi, though some might not go that high.

If your Wayne is single stage, 150 is way too high for it to be pumping to, more like 125 to 130 max.

Shop pressure is usually around 100 psi. You need a regulator on the tank outlet or at the various outlets if you have a system (or a single whole system regulator). If you hold about 100 psi in a system, you probably will be seeing about 90 psi at the far end of the hose while in use. Most air tools are designed to operate properly at 90 psi inlet pressure.

I run an Ingersol Rand, also an older 2 stage. The techs told me to time it to cutoff to determine wear and when to rebuild.

When I timed mine, it was OK but had a hard time keeping up with my sandblaster. They also recommended reducing the cutoff pressure to raise the cfm delivered.

Now is set at 125 psi cutoff and is happy. I reduce pressure as needed at the stub. Also didn't think much of the standard air filter size, substituted a car air filter. Adding an additional tank greatly reduced the number of cycles and cool off time between.

If you can determine proper time-to-cutoff for your size tank/pressure, you can determine how worn it is.
