I have a Carette air compressor with Joe Brancato Alpha filter and I am having problems. The compressor has about 20 hours on it.
It appears to me that the compressor is putting out less volume of air per unit time then it did originally. Here is what I have done.
Compressor is off.
Connected a 97 cu ft air tank at 3500 psi.
Tank valve closed.
Turn compressor on.
Compressor fills the filter and hose. Pressure will increase to 4500 psi and compressor shuts off (just like it should).
I bleed off all air from filter and hose.
Tank valve still closed. I start compressor and increase pressure to about 3000 psi.
I open tank valve slowly and equalize pressure between hose and tank.
Pressure in tank begins to increase very slowly. From 3500 to 3800 psi in 50 minutes. The tank used to fill from 3500 to 4500 in about an hour.
I have soap tested all joints and there are no leaks.
The compressor is cool to the touch throughout the cycle.
Does anyone have any ideas on how I should proceed?
