There are usually some clean workbenches in the purification room, but the meticulous application method is not well understood, assuming that the operation error will have an impact on the overall purity. So today we will introduce the characteristics and principles of clean workbench, so that we can better use this equipment.

潔凈工作臺是一種凈化設備，可以除塵、除菌，提供一個良好的工作環境，將污染的空氣排出，避免對人和環境構成的危害，在微生物實驗室中運用較多，還有醫院手術室、精密電子等行業也有應用。

Clean workbench is a kind of purification equipment, which can remove dust and bacteria, provide a good working environment, discharge polluted air, avoid harm to human and environment. It is widely used in microbiological laboratory, hospital operating room, precision electronics and other industries.

潔凈工作臺特性：1、潔凈度等級為100級的操作環境，關于粒徑≥0.5μm的塵埃≤3.5顆/升。2、水平層流型或垂直層流型。3、采用超薄型無隔板高效空氣過濾器，占用空間小。4、采用觸摸式電子控制面板，風機風量可無級調理，保證工作區的風速不斷處于理想狀態。5、不銹鋼工作臺面，有機玻璃圍擋，可配備紫外燈遠程控制電氣接口。

Clean workbench characteristics: 1. Cleanliness level of 100 operating environment, with respect to particle size (> 0.5 um) of dust (< 3.5 particles/liter). 2. Horizontal laminar flow pattern or vertical laminar flow pattern. 3. Ultra-thin non-baffled high-efficiency air filter, occupying less space. 4. Touch-type electronic control panel is used to stepless adjust the air volume of the fan to ensure that the wind speed in the working area is constantly in an ideal state. 5. Stainless steel working table, plexiglass enclosure, can be equipped with ultraviolet lamp remote control electrical interface.

潔凈工作臺結構：采用直接智能控制方式，設有風機、照明、除靜電等開關。整個機箱采用薄鋼板制造，外表烤漆，活動靈活，運用便當，易于清潔。

Clean workbench structure: direct intelligent control mode is adopted, with blower, lighting, static electricity removal switch, etc. The whole chassis is made of thin steel plate, with paint on the outside, flexible movement, convenient use and easy cleaning.

潔凈工作臺原理：

Principle of Clean Workbench:

潔凈環境是在特定的空間內，潔凈空氣(進濾空氣)按設定的方向活動而構成的。以氣流方向來分，現有的超凈工作臺可分為垂直式，由內向外式以及側向式。從操作質量和對環境的影響來思索，以垂直式較優越。由供氣濾板提供的潔凈空氣以一個特定的速度降落經過操作區，在大約操作區的中間分開，由前端空氣吸入孔和后吸氣窗吸走，在操作區下部前后部吸入的空氣混合在一同，并由鼓風機泵入后正壓區，在機器的上部，30%的氣體經過排氣濾板從頂部排出，大約70%的氣體經過供氧濾板重新進入操作區。為補充排氣口排出的空氣，同體積的空氣經過操作口從房間空氣中得到補充。這些空氣不會進入操作區，只是構成一個空氣屏障。

Clean environment is made up of clean air (inlet and filter air) moving in a given direction in a specific space. According to the direction of airflow, the existing ultra-clean worktable can be divided into vertical, internal-external and lateral. Considering the operation quality and environmental impact, the vertical type is superior. The clean air provided by the air supply filter plate falls through the operation area at a specific speed, separates in the middle of the approximate operation area, is sucked away by the front air suction hole and the rear air suction window, and is mixed with the air sucked in the lower part of the operation area, and is pumped into the positive pressure area after the blower. In the upper part of the machine, 30% of the air is discharged from the top through the exhaust filter plate, and about 70% of the air is discharged from the top. The body enters the operation area again through the oxygen supply filter plate. To supplement the air discharged from the exhaust port, the same volume of air is supplied from the room air through the operating port. These air will not enter the operating area, but constitute an air barrier.

當我們在凈化室內運用潔凈工作臺的時分需求留意性能特性、結構特性、工作原理等方面的學問，才干更好的堅持維護凈化的環境。
