Giải thích
The governor controls when the compressor pumps air into the storage tanks. When tank pressure reaches the cutout level (around 125 psi), the governor stops the compressor from pumping. When pressure falls to the cut-in level (around 100 psi), it allows the compressor to start pumping again.
