Regulator not regulating air pressure...

Hello,


I have a Craftsman 3 gal. Air Compressor (1 hp), which stopped regulating air pressure.

I replaced the stock regulator with an identical part, and am still having the same issue.

If the main tank has 100 psi, shouldn't I be able to adjust the regulator say, to 20psi or 60psi?

No matter how where I turn the knob, the gauge only represents what's inside the main tank. I recall the original regulator before it failed, did just that--I could manipulate the pressure coming from the main tank. Any suggestions on what is happening?

Thanks,

Mike

That was it. Before looking at your diagram, I didn't know the regulator was unidirectional, and the arrow on the back was not obvious. Turned the unit around and now it works great. Simple solution. Thank you for your expert feedback.

Check to be sure that the arrow on the regulator is pointing toward the discharge coupler and not the air tank.

Please confirm the correct orientation.

Thanks for the reply. If I release pressure from the regulator all the way by turning the knob counterclockwise, the regulator and tank gauges will be the same until the system is exhausted. I can hear the regulator hissing when the pressure is dropped. Also, the gauge is separate from the regulator. I hope that answers your question.

Regulator?
by: Doug in s.d.ca

Perhaps the "identical part" actually isn't.

If you turn the reg all the way down (or off), and you release pressure through a hose or whatever, does it then drop the pressure?

Is the gauge integral to the reg or separate?
