Compressors in OCFRD have automatic drains that activate how often?

Compressors in OCFRD have automatic drains that activate how often?

• A. Every 1-2 minutes
• B. Every 10-15 minutes and when the compressor shuts down
• C. Every 20-25 minutes
• D. Only when the compressor shuts down

Answer: (B)

Automatic drains are there to keep the breathing air dry by removing condensate that forms when compressed air is produced. Condensation can build up in the lines as the air cools, and if water isn’t drained, it can contaminate PPE or affect the performance of the respirator system. The standard setup is to purge condensate at regular intervals—about every 10 to 15 minutes—plus a purge when the compressor shuts down. This combination prevents moisture from accumulating during operation and ensures the lines are dry when the system restarts. Draining more frequently would be unnecessary and could waste air, while draining only at shutdown would leave moisture in the lines during use.
