Development of NBC Filtration and Ventilation Unit / 医疗卫生装备

Objective To design and produce a kind of NBC filtration and ventilation unit with the function of filtering biological aerosols and chemical poisonous gas and so on in the air,providing new clean air for the medical shelter.Methods The filtration unit and ventilation unit were united in principle of manipulability and repairability by modularization method.Results Structural dimensions and vibrational noises of the unit were reduced,and manipulability and repairability were improved.Conclusion The unit can meet the demands of biological and chemical protection for the medical shelters,and the structural design of fast fitting and so on can meet the requirements of fast responses.
