What does the term 'cut-out pressure' refer to in the context of air-compressor tests?

The term 'cut-out pressure' in the context of air-compressor tests refers to the highest pressure at which the air compressor will stop pumping air into the system. This is a critical setting because it ensures that the air tanks have enough pressure to function effectively without over-pressurizing, which could lead to safety hazards or equipment failure. The cut-out pressure is typically set by the manufacturer and is designed to optimize the performance of the air braking system, allowing it to maintain efficient operation while ensuring safety and reliability.

Understanding cut-out pressure is essential for proper maintenance and operational checks in vehicles equipped with air brake systems, as it directly relates to the effective functionality of the brakes during use.
