Is this normal,it stops when it shuts off.This is a model 3Z492.
Allen, no, this is not normal.
You say that it stops when it shuts off. At what pressure does it shut off?
If it is the normal cut out pressure, often between 120 and 150 PSI, then your PRV may be failing. Get it fixed.
If the compressor is shutting off at a much higher pressure than 15o PSI, then your pressure switch may be cooked.
Either case, your compressor is dangerous, and it were me, I would not use it until it was running, and stopping, properly.
speedaire 3z530a ~ leaking?
For Some reason it is air out from air drain outlet it is confused me need to find out why is it
still letting air out
Peter, if it is air leaking from the tank drain, either tighten it or replace it if you cannot shut it off.
If it's air leaking from the little valve on or near your pressure switch click on the VALVE LINK and then click on CHECK VALVE.
That could be your problem. If neither of these, then some more information will be needed for me to help further.
