垂直流净化工作台

来源：浙江孚夏医疗科技有限公司分类：科技文献 2023-05-26 11:20:49 11阅读次数

垂直流净化工作台采用垂直单向流净化原理的气流形式，降低噪音。将离心风机、静压箱和高效过滤器组合成一个整体的单元结构。本产品可采用单独的工作台，以减少振动的影响。上送风体与下工作台可分离，移动方便。出风口的扩散器应配备照明荧光灯和紫外线杀菌灯。
　　洁净空气（进气过滤空气）在特定空间内按设定方向流动形成洁净环境。现有洁净工作台按气流方向可分为立式、由内向外式和横式。考虑到操作质量和对环境的影响，立式更好。
　　送风滤板提供的洁净空气以特定速度通过操作区，在操作区中间分离，由前吸风孔和后吸风窗吸走。作业区下部前后吸入的空气混合在一起，由鼓风机泵入后正压区。在机器上部，30%的气体通过排气滤板从顶部排出，约70%的气体通过供氧滤板重新进入作业区。为了补充从排气口排出的空气，通过操作口从室内空气中补充相同体积的空气。这种空气永远不会进入操作区域，而是形成空气屏障。
　　垂直流净化工作台采用FFU高效过滤机组专用风机，具有寿命长、噪音低、免维护、振动小、无级调速等特点。工作寿命可达50000小时以上。风机调速性能稳定，在高效过滤器终阻力的情况下仍能保证风量不变。减小静压箱尺寸，再配以全不锈钢框架和黑色有机玻璃制成整个工作台看起来更好用。易于拆卸的大风量预过滤初效过滤器，更好地保护高效过滤器，保证风速。垂直流超洁净工作台，开放式桌面，操作简单。

超净工作台和生物安全柜的四大区别
请不要用超净工作台代替生物安全柜使用

生物安全柜与净化工作台在许多从业人员看来区别不大，其实它们无论是功能还是用处方面都有许多不同。
