Negative pressure isolation ward is deﬁned as a ward with a pressure difference between the inside and outside of the ward. The pressure inside of the ward is lower than the outside pressure, therefore air inside the ward cannot escape to the outside. This negative air machine design helps to prevent the contaminated air in the ward from escaping to the outside.
When an indoor negative air machine or exhaust puriﬁcation unit (EHU) is applied in a ward without exhaust system, part of the indoor contaminated air can be recirculated and absorbed to the puriﬁcation unit, while part of the indoor contaminated air can be exhausted after puriﬁcation to maintain the ward in a negative pressure condition. The indoor exhaust puriﬁcation unit uses primary and HEPA ﬁlter to capture the dust particles carrying viruses and microbes.
