FIELD: construction, ventilation.

SUBSTANCE: invention relates to ventilation and air conditioning in facilities with aggressive and explosive media. Positive pressure ventilation system for facilities with aggressive and explosive media consists of forced air duct, on which there is a heater, and fan with a discharge pipe. The air duct is linked with outside air and is connected to the suction pipe of the fan, which comes with a foamy evaporative cooler. The source of the aggressive and explosive gas, for example, oxygen generator is connected using pipes to a coil, located in the active zone of the foamy evaporative cooler.
