Aux 1 Unit 7 Q6

Correct Answer: B) Employing a combination of air dryers, filters, and separators to remove moisture and contaminants from the air

Explanation: Achieving clean, dry air in a pneumatic system typically involves using a combination of air dryers, filters, and separators. These components work together to remove moisture and contaminants, ensuring that the air supply is suitable for use in the system and helps maintain the reliability and efficiency of the system.

Correct Answer: B) By cooling the air to condense moisture, which is then removed from the system

Explanation: A refrigerated air dryer cools the compressed air, causing moisture to condense. This moisture is then removed, resulting in dry air that is suitable for use in the pneumatic control system.

Correct Answer: B) To prevent moisture from freezing and causing blockages in the air lines and components

Explanation: In cold environments, moisture in the air can freeze, leading to blockages in air lines and components. Dry air prevents this, ensuring the system operates reliably even in low temperatures.

Correct Answer: B) To remove moisture from the compressed air to prevent corrosion and freezing

Explanation: An air dryer removes moisture from compressed air, preventing corrosion, rust, and freezing, which are critical for maintaining the integrity and reliability of the pneumatic control system.

Correct Answer: B) It can cause the valves to stick, corrode, or malfunction, leading to unreliable operation

Explanation: Moisture in the air can cause pneumatic control valves to stick or corrode, leading to unreliable operation and potential system failure. Clean, dry air helps ensure that valves and other components function properly.

Correct Answer: A) Coalescing filter

Explanation: A coalescing filter is used to remove solid particles and fine aerosols from the air, ensuring that the air entering the pneumatic system is clean and free of contaminants that could damage components.

Correct Answer: B) It removes contaminants such as dust, dirt, and oil mist from the air before it enters the system

Explanation: The air filter is responsible for removing contaminants such as dust, dirt, and oil mist from the air, ensuring that only clean air enters the pneumatic system, which is essential for maintaining system efficiency and preventing damage.

Correct Answer: B) Reduced wear and longer lifespan of pneumatic components

Explanation: Clean, dry air reduces wear on pneumatic components, minimizes the risk of damage, and helps extend the lifespan of the system, ensuring efficient and reliable operation.

Correct Answer: B) To prevent contamination, corrosion, and freezing that can damage components and reduce system efficiency

Explanation: Clean, dry air is crucial in pneumatic systems to prevent contamination, corrosion, and freezing, which can damage components, lead to malfunctions, and reduce the overall efficiency and reliability of the system.

Correct Answer: B) It can introduce contaminants that clog, wear down, or damage system components, leading to costly repairs

Explanation: Contaminants in the air can clog, wear down, or damage pneumatic components, resulting in costly repairs, downtime, and reduced system efficiency. Clean air is essential for maintaining the health of the system.
