Why 165 PSI cut out ?
by Pete B
Quincy QT-5 running fine for 4 years. Starting to hear a little bit of knock just before pressure switch cuts out at 165 PSI. All of my tools run at about 90 PSI. Regulator after receiver tank is set to 100 PSI.
The question is why not set pressure switch to open at 120 PSI?
Doesn't it sound logical that the compressor would have extended life and run more efficiently only compressing to 120 rather than 170? Am I missing something here? Thanks.
