This design enables vertical unidirectional flow ultra clean workbenches to be widely used in various fields such as laboratories, biopharmaceuticals, optoelectronics, microelectronics, and hard disk manufacturing.

IIInstructions for Use

When operating a vertical unidirectional flow ultra clean workbench, the following key points should be noted.1Ensure that the workbench is clean and avoid affecting air circulation and filtration efficiency.2. ToRegularly check the status of the high-efficiency filter to ensure its stable performance and no damage, in order to ensure the cleanliness of the air.3It is necessary to follow the correct operating procedures, such as adjusting the wind speed appropriately and avoiding frequent switching, to ensure the stability and durability of the workbench.

1Power supply and wiring

The power supply of a vertical unidirectional flow ultra clean workbench usually adopts a three-phase four wire system, where one neutral wire is connected to the machine casing and firmly grounded, while the other three phase wires provideThe working voltage is 380V. When wiring, a specific sequence must be followed, otherwise it may cause the fan to reverse, thereby affecting the normal use of the ultra clean table. Once a wiring error is found, the power should be immediately cut off, the positions of two phase wires should be swapped, and then reconnected to correct the problem. At the same time, it is important to check if all three-phase wires are correctly connected to avoid the risk of abnormal machine noise or even motor burnout caused by poor contact.

2Air inlet and filter

The air inlet of the super cleaning table is usually located at the bottom of the back or front, and is equipped with ordinary foam plastic sheets or non-woven fabrics in the metal mesh cover to intercept large particles of dust. These components should be regularly inspected and cleaned to ensure their effectiveness. At the same time, it should be ensured that there are no air leakage holes in the parts other than the air inlet to ensure/Verify the cleanliness of the air. The metal mesh cover on the front of the workbench is a super filter. If it is used for a long time or clogged with dust particles, it should be replaced in a timely manner to ensure that there are no issues/The effect of bacterial manipulation.

3Usage environment and maintenance

The ultra clean bench can be used in general laboratories in temperate regions, but in tropical or subtropical regions or dusty environments, it is recommended to use it indoors with better conditions and avoid placing the air intake hood facing open doors or windows to ensure the longevity of the filter/Fate. none/The mushroom room should be regularly dusted and disinfected/Toxic treatment, including the use of alcohol/Chemical disinfectants such as Jing, phenol, and Xinjier Mie, as well as fumigation and ultraviolet disinfection/Bacterial lamps and other methods are used to maintain cleanliness/Bacterial state. At the same time, it is recommended to install ultraviolet lamps inside the vaccination box for irradiation and extinguishing/Bacteria. When using ultraviolet lamps, attention should be paid to their irradiation time and irradiation range to ensure that there are no/The effect of bacterial manipulation. Due to the harmful effects of ozone on health, the ultraviolet lamp should be turned off before entering the operating area, and wait for more than ten minutes before entering.

UV lamps can also be installed on ultra clean workbenches, but it is necessary to ensure that they are installed outside the lighting lampshade and staggered with the lighting fixtures to avoid affecting the lighting during work. Please note that ultraviolet lamps cannot be installed inside the lighting cover because ultraviolet rays cannot penetrate glass, and their lamp tubes are made of quartz glass, unlike silicate glass.

The vaccination room should be kept simple, and items that are not directly related to work should not be placed to ensure that there are no/Bacterial state. At the same time, the air inside the vaccination room should be isolated from the outside air, and the ventilation ducts should be as closed as possible. The ventilation duct can be set as upper and lower ventilation windows, with a slightly larger ventilation window area and coverage4 layers of gauze for simple dust filtration.

After the work is completed, windows can be opened for sufficient ventilation, and then sealed/Close it. In short, the vaccination room should be kept clean and dust-free/Bacteria and fresh air are beneficial for work. The gauze covering the ventilation window should be changed regularly.

However, achieving the above ideal design solutions is often not easy. But as long as it is strictly followed, there is nothing/The operating procedures for bacteria include using a super clean table for protection in rooms with open doors and windows, and the contamination rate of inoculation can still be controlled at an acceptable level in production.
