Exhaust Handling Unit

Convertable Negative Pressure Unit

ETL Certified

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 design helps to prevent the contaminated air in the ward from escaping to the outside. 

When an indoor exhaust handling 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.


  • Negative pressure applications

  • Multiple operating modes: indoor air recirculation and exhaust
