Air compressor problem

Recommended Posts

Got a 1961 B81 that takes atleast 5 minutes to build 90 pounds. I took the line that goes to dryer off and it seems to be supplying air well. There are no leaks anywhere so were is the air going. Could it be a problem with dryer or something simple like the governer ?

What happens when you bypass the drier?  If it is getting good air to it then I would remove it and see if it works fine without it.  If the drier is anything like we have on our compressor at work it has a disectant(sp) filter that could be clogged.  If we run the old compressor it pumps lots of oil and it will clog the filter til hardly any air gets through the filter so I have to bypass the filter if I have to run it.

The unloader valve in the compressor could be leaking back and not actually making good pressure.  Or the governor is holding it open?
