Air to Press start up?

also, a rotary screw is meant to run 100% duty cycle, so even if it did start running constantly overnight, nothing bad should happen.

I do like rich's idea of a hole in the ball valve, but what I may do is a 1/8" hose "bypass" around the ball valve with a second gate valve for maintenance when needed.

Just buy a ball valve with a brass ball and you can drill it in less than a minute.

I like to follow manufacturer's recommendations

our atlas copco compressor has two PSI setpoints and is programmable for day/week/month selections of setpoints.  15 minutes before the shift comes in the compressor is set to 110 psi, and 15 minutes after the shift leaves it will maintain 60 psi.  we were shutting it off at night and turning off the air before the chiller but this is easier.

oh

after working on a press (maintenance) with the air off, i always slowly open the air valve - ive had pneumatic oilers pop off because ive failed to seat the o ring correctly after filling it with oil.

Thanks.  I was just staring at a chromed ball valve thinking "There is no way in hell I am drilling this with my crappy tools"...

make sure the ball is bronze and not Stainless and it will be easy.

Compressor on here all the time, Where are you losing air ?  if my tank is full at the end of the day it usually doesn't even cycle on overnight.

Somehow I think we might be moving from the question I asked, but still tons of good info to know, our compressor stays full of air all the time I just turn power it down when we leave and turn it back on when we are back in the shop.  What I don't do is leave the air on to our press full time, which from what Rich sez is perfectly fine with there press's, so I thinking that is another great quality to owning an M&R press or speaks highly of there equipment.  I don't know what other press manufacturer's recommend for there press as they are not on here to say, but our press is an all air press which I don't know if that makes a difference or not hmmm.

I left the air on to our Javelin the entire time we owned it as well.

my thinking, is that the air lines, valves, etc all will endure LESS stress if you just leave the air on all the time vs inflating/deflating them every day.

things usually break when they're stressed and un-stressed repeatedly.

We run two in tandem, with a device that alternates them. At the end of the day, we close the at the press, then both compressors are shut down, and the valves on each are closed. I think you probably made something slam into something else, as you usually let the air in slowly, it wouldn't happen. If it still works, you're probably OK...
