Do not use standard dew point 40C (symbol: L) type, standard dew point 60C (symbol: S) type and IDG30A, 50A, 30HA, 50HA for dehumidifying breathing air. Do not use only outlet air (dry air) in a closed room. 1. Consider the purge air flow rate. Find the purge air flow rate from the charts and calculate the required outlet air flow rate + purge air flow rate.
