Monitoring Dew Point
Medical facilities rely on clean dry compressed air for the reliable operation of pneumatic controls, respiratory therapy apparatus, ventilators, breathing air and hyperbaric chambers. The NFPA (National Fire Protection Agency) has established ANSI/NFPA-99, which requires that the dew point of compressed air be continuously monitored and that the monitor provide an alarm if the dew point exceeds 39ºF/4ºC. In addition to dew point, CO (carbon monoxide) concentrations in compressed air are required to be monitored and should not exceed a threshold level of 10 ppm. Canadian standard CAN/CSA Z305.1-92 states that medical breathing air must have a maximum water vapor concentration of 1630 PPMv which corresponds to +5ºF/-15°C dew point.
