Super clean working table provides a clean and sterile working environment for scientific research and production departments

Application of super clean working table: it is widely used in scientific research and production departments that need local clean and sterile working environment, such as medicine and health, biopharmaceutical, food, medical science experiment, optics, electronics, sterile room experiment, sterile microorganism inspection, plant tissue culture and inoculation It can also be connected into an assembly line with the advantages of low noise and mobility It is a kind of air purification equipment which can provide local high cleanliness working environment with strong universality Its use has good effect on improving process conditions, improving product quality and increasing yield The clean environment of super clean working table principle is formed by the flow of clean air in a specific space in a set direction According to the air flow direction, the existing super clean table can be divided into vertical type, from the inside out type and lateral type Considering the operation quality and the impact on the environment, the vertical type is superior The clean air provided by the air supply filter plate descends through the operation area at a specific speed and is separated in the middle of the operation area It is sucked by the front air suction hole and the rear suction window The air sucked in the front and rear parts of the lower part of the operation area is mixed together and pumped into the rear positive pressure area by the blower In the upper part of the machine, 30% of the air is discharged from the top through the exhaust filter plate The super clean workbench About 70% of the gas re enters the operation area through the oxygen supply filter plate In order to supplement the air discharged from the exhaust port, the same volume of air is supplemented from the room air through the operation port These air will not enter the operation area, but form an air barrier The maintenance methods of the super clean bench are as follows: 1 According to the actual use of the biosafety cabinet, remove and clean the primary effect filter regularly, and the cleaning cycle is generally 3-6 months (if it is not washed for a long time, dust accumulation will affect the insufficient air intake and reduce the cleaning effect) 2 When the initial effect air filter can not reach the ideal cross-sectional wind speed after normal replacement or cleaning, adjust the working voltage of the fan (turn the knob) to achieve the ideal uniform wind speed (adjust the working voltage of the fan to 80V ~ 90V when the new workbench is in use) 3 Generally, after 18 months of use, when the working voltage of the fan of the biosafety cabinet dispatched by three persons is adjusted to the high point, and the ideal wind speed is still not reached, it means that the high-efficiency air filter has too much dust (the filter hole on the filter material has been basically blocked, so it needs to be updated in time) Generally, the service life of the high-efficiency air filter is 18 months 4 When replacing the high efficiency air filter, pay attention to the correctness of the model, specification and size (configured by the original manufacturer), follow the arrow wind direction device, and pay attention to the surrounding sealing of the filter, without leakage.
