The Importance of Dew Point Monitoring in Compressed Air & Meeting NFPA 99 Medical Air System Standards
Compressed Airline Monitor for Medical Air
Dew point is defined as the temperature to which a gas (e.g. air) must be cooled, at constant pressure, for water vapor to begin to condense to liquid water. In other words, when the dew point temperature has been reached, the gas is fully saturated with water vapor. Monitoring the dew point in compressed air lines is critical in medical and hospital air systems because of the possible risk for the growth of microorganisms. Risks associated with letting dew point levels go unchecked in medical air/gas systems is the possible formation of bacterial growth in water droplets containing legionella germs. This can cause serious and often deadly lung infections. Also, when moisture levels are too high, water in medical air systems can shut down patient ventilators and may cause serious physiological harm.
