FDNY COF to Operate and Maintain Air Compressors (A-35) 2025 – 400 Free Practice Questions to Pass the Exam

Draining water from the air receiver tank is essential for several reasons related to the reliable operation of the air compressor system. When air is compressed, it inherently carries moisture, which can accumulate in the air receiver tank. If this moisture is not removed, it can lead to corrosion of the tank’s interior surfaces. Over time, corrosion can weaken the tank structure, potentially leading to leaks or even catastrophic failures.

Furthermore, excessive water in the tank can impact the quality of the compressed air. Moisture in compressed air can cause issues with equipment that relies on clean, dry air, leading to malfunction or damage to pneumatic systems. By regularly draining the water from the air receiver tank, operators ensure that the air is not only dry but also free from contaminants, thus maintaining the intended air quality for downstream applications.

Additionally, maintaining a proper operational environment prevents the buildup of water that could also contribute to freezing in colder conditions or contamination that may affect the performance of pneumatic tools and systems. This practice thus plays a critical role in ensuring the compressor operates efficiently and effectively.
