At about what air pressure does the governor cut the compressor back in so the system can rebuild pressure?

• A.Around 30 psi
• B.Around 150 psi
• C.Around 100 psi
• D.Around 60 psi

Why

Cut-in is roughly 100 psi, well above the low-air warning level. That gap gives the compressor time to restore working pressure before the system gets anywhere near a danger zone.
