The inlet water pressure should be in the range of 0.1–0.7 MPa (A
reducing valve must be installed if the inlet water pressure exceeds
0.7 MPa.), and the temperature should be in the range of 1°C–40°C.
The wet film humidifier should use tap water (no water treatment
facility needed for the inlet water) that meets the following
