轴流式风机是微生物实验室中常用的一种简单的通风设备,它的风压小,不宜接联标准滤器。为防止安装在微生物实验室、感染动物房和消毒间的轴流风机将污染空气直接排出室外,我们用纱布作为滤材覆盖风机的进气口,并测定了覆盖在轴流风机上的纱 Axial flow fan is a simple ventilation device commonly used in microbial laboratory, it’s small wind pressure, should not be connected standard filter. In order to prevent the axial air blower installed in the microbiological laboratory, the infected animal room and the disinfection chamber from discharging the contaminated air directly to the outside, we covered the air inlet of the fan with the gauze as the filter material and measured the yarn covering the axial fan
