What is the purpose of the compressor bleed air filter?

• A. Prevents foreign objects from entering
• B. Removes moisture from the air
• C. Increases bleed air pressure
• D. Reduces noise in the compressor

Answer: (A)

Bleed air filtration protects the system by removing solid contaminants from the air before it reaches pneumatic components. By catching dirt, particles, and debris, the filter prevents damage and wear to valves, actuators, seals, and anti-ice or other bleed-air devices that rely on clean air. Moisture removal is handled by separate moisture separators, not the filter, and the filter isn’t meant to increase pressure or reduce noise. Its primary job is simply to keep the bleed air clean and free of debris.
