Ventilation system for protective garments
摘要:
An improvement in ventilating protective garments used against chemical agents. There is provided an arrangement of the air supply and the air exhaust so that the air cools the occupant and sweeps across the visor of a headpiece to prevent fogging. A regulator is used to maintain a degree of inflation in the garment by the incoming air.
