Low air alarm

You know, I saw that I didn't update my fix, prior to today and I just did.
If your buzzer is on always, and doesn't turn off, then it's one of those switches...
also, it might be too much condensation in the air tanks... make sure they are drained regularly.
good luck

My 95 internatiol low pressure air alarm only comes on at 30 psi supposed to around 60 psi is their an adjustment of some sort for this I'm not sure what the problem is

 

Yeah that's a mechanical switch, there isn't an adjustment but replacing it with the right one will help.
