What is the pressure set between the Air Dryer and Main Res?

The pressure set between the Air Dryer and the Main Reservoir is typically calibrated for optimal performance within a specific range. In railway traction systems, the correct pressure helps ensure that the air drying system effectively removes moisture from the compressed air, which is essential for maintaining system efficiency and preventing issues like corrosion or freezing.

Setting the pressure at 1050 kPa is standard for many systems, allowing for sufficient air flow and separation of moisture while also ensuring that all components operate within their designed capabilities. This pressure helps maintain a balance that allows the system to function effectively under various operating conditions.

The other pressure levels, while they may be used in different contexts or systems, do not align with the commonly recommended setting of 1050 kPa, which is widely adopted for optimal performance of air dryer and main reservoir interactions in traction applications.
