Black Max 80 Gallon 2 stage taking a long time too fill tank.
by Richard Brockman
Have Black max 5hp 80 gallon tank 2 stage Air compressor.
It starts without issue and builds PSI to 150 when it shuts off.
There are no air leaks anywhere in the system.
However it seems to take a long time to build pressure.
From 0 PSI to 150 PSI it takes almost 8 minutes of run time. My last air compressor was a single stage 5hp 80 gallon single stage v type compressor and went to 140 PSI in 5.5 minutes.
Is the build pressure on my 2 stage Sanborn compressor taking too long?
How long should 2 stage compressor pump in good working order take to fill a 80 gallon tank.
I need to know if I need to rebuild the pump.
