ABSTRACT:
A humidifer for aqualung equipment comprises a source vessel housing moistening water which is or is not contained in a fibrous material member, and a water applying passage disposed to communicate the source vessel with the gas supply passage of the respirator and normally shutting off such communication, whereby when pressure in the gas supply passage is temporarily lower than that in the source vessel upon respiration of the user, such pressure difference may cause the water in the source vessel to be applied in a sprayed form from the applying passage into the gas supply passage. A further humidifier includes a water containing fibrous material member disposed directly in the gas supply passage of the respirator and kept to be in a water containing condition by supplying water through the aforementioned water applying passage.
