You're talking the one at the top?

You don't have one in the center, right?

That would be bypass air from one or both cylinders. Ring job.

3Z180 leaking
by: Bill

Hey Randy, typically the term governor refers to a gasoline powered motor.

Your twin cylinder 3Z180 is being run by an electric motor I would think?

If so, the governor you refer to is likely the pressure switch.

If air is leaking from there while the compressor is running, the unloader valve is likely the problem. Fix that and stop the leak.

If air is leaking from the pressure switch when the compressor is off, it's likely the tank check valve that's failed. Clean, test or replace that to solve the problem.

Once those leaks are fixed, if the compressor will still not build air, see the troubleshooting page on this site for links to pages that address that.

3z180 speedaire
by: Randy

It is a speedaire 3z180. It does run and fill the tank up somewhat but never fills up enough to operate the pressure switch. The air is coming out of the fitting located at the governor housing.

Maybe pilot adjustment, but it's kinda tough to say, not having much idea of what machine you're talking about?

Exactly when is it happening? Does it ever stop?
