What is the first reservoir after the compressor typically called?

The first reservoir after the compressor is typically referred to as the "supply reservoir." This reservoir plays a crucial role in the air brake system. After air is compressed, it must be stored before being distributed to the brake components. This initial reservoir acts as a storage tank where the compressed air is held for immediate availability when brakes are applied.

Different types of reservoirs may have specific functions, like managing moisture or filtering air, but the primary purpose of the supply reservoir is to ensure that there is sufficient compressed air available for brake actuation. Having this reservoir at the start of the distribution system is critical because it helps maintain consistent air pressure and flow, which is vital for the reliability and effectiveness of the braking system.

The other options mention terms associated with air reservoirs, but none accurately describe the role of the first reservoir following the compressor as effectively as the supply reservoir does.
