What are the cut-out and cut-in pressures for the Grovner of the air suppresses?

The correct choice indicates that the cut-off pressure is set at 125 psi and the cut-in pressure is set at 100 psi. These pressures are crucial because they determine the operational range of the air suppressor system. The cut-off pressure refers to the point at which the air compressor stops generating air, while the cut-in pressure is the threshold at which the compressor restarts to maintain the system pressure.

This specific setting ensures that the system operates efficiently within a safe range, preventing the compressor from running continuously, which can lead to overheating and increased wear. Maintaining these pressures helps protect the equipment and ensures that it performs optimally.

In contrast, other options would present different operational thresholds, which may not align with the necessary specifications for the Grovner air suppressor, thus potentially compromising performance and safety.
