How many hours must the medical air compressor system be operating normally before an air quality test can be performed?

• A. 2
• B. 8
• C. 12
• D. 24

Answer: (C)

Air quality testing must be done after the system has been allowed to reach a steady, normal operating state. When a medical air compressor starts up, oil carryover, moisture, and particulates can be higher than usual and the dryer and filters haven’t yet settled into their normal performance. Giving the compressor a substantial period of normal operation lets condensate purge and the components stabilize, so the sample collected reflects the air the patients actually receive rather than startup transients. This makes the test results representative and compliant with standard medical gas quality requirements.
