what's your compressed air system pressure?

[Rick in PA]

I work for a typical small US industry. Some of the things we design use compressed air. This leads me to ask, what is your compressed air system operating pressure (and what country is your company in)?

Our company has a system pressure of 100 psi (~670 kPa?).

When i was young (1970's), I worked at a service station that had a rather "stiff" compressed air system that maxed out at 150 psi.

What's your experience?

My shop class in high school had about 175 psi.

My home compressor tops out at 90 PSI, the one at work tops out at 120 PSI.

Last shop was 185-190 on the high end compressors kicked in at 165 and 145 I think it was.

Current place about 145.

120 for our laboratory. Regulated down to 40-60 most everywhere though.

Mine cuts off at around 120 and kicks in at around 90.

work is 125-130psi from what I've seen.(USA) At Home my little 1 gallon POS (shoudln't have bought it) Cambell/H compressor barely gets to 100psi.

My dad's compressor is 120psi at his house.

How much pressure do you need?

 

[NJC]

110psi in shop.

All (I hope) air tools are rated for 100psi - and a big mobile compressor will run a couple of jack hammers at 100psi all day.Most shop compressors are set to about 120-130psi,kicking in at 80psi....averages out at 100psi.I used to work as a compressor tech 30 years ago,and that is how we set them up.But really,it is about supply not pressure.

When the compressor at our shop died this year we got a new Chinese one.The old one was running at 150psi,and I expected it wouldn't last long.The new one was set at 160psi,kicking in at 100psi.The boys thought it was great.But I knocked it down to 130,kicking in at 80psi.They complained,having been used to high pressure for so long.I have brought the kick in pressure up to 90psi....but now it keep switching on too many times in a day.I might sneak it back down now they are used to lower pressures.

Bit of a concidence here! Compressor at work is in an old unused restroom area. Don't inspect very often, but noticed today it sounded like head bleed-down system was staying on after shutoff. Close inspection showed the pressure controll onoff switch had a leaky diaphram. Waited till after closing to shut it down (tire,wheel align, oil change, shop. When the air is down, might as well be closed anyway) and replace. Attaches to small pipe on side of 80 gallon tank, then pop-off valve, gauge,attach to multiple ports on switch. Took maybe 15 minutes to change out switches, but I didn't want to stay over long enough to see where it starts-stops. Someting else to look in on tomorrow.

at home 90-120 psi, last place I worked 80-90 psi constant.

in a commercial setting you'd be amazed at how much energy is wasted by making more pressure then needed.
