How many blowers are in the lower portion of each EAPS, and what do they do?

The correct choice indicates that there are two blowers in the lower portion of each EAPS (Engine Air Particle Separator). These blowers play a crucial role in the operation of the system by pulling scavenge flow. This means that their function is to assist in removing contaminants and particulates from the airflow before it enters the engine, which helps to ensure cleaner air and enhances engine performance and longevity.

By maintaining a clean intake air passage, the blowers contribute to the overall efficiency of the engine, as well as the reliability of the aircraft during operations. The design and function of these blowers are critical for the effective performance of the EAPS, which is designed to protect the engine from harmful debris and contaminants in the air intake, especially in harsh environments.
