It is very important to keep the laboratory clean. The dust in the outdoor atmosphere will enter the laboratory through ventilation and ventilation. Excessive dust and air in the experiment will not only affect the detection results, but also the particles will fall on the surface of the components of the instrument and equipment, which may cause obstacles. It may even cause a short circuit or other potential danger. Clean laboratories need to spend money. It is recommended that they do not need special clean laboratory design. If necessary, large-scale precision instrument rooms and special laboratories can be designed. Generally, 10,000-grade purification requirements can be achieved. If there are multiple clean labs, the air delivery and exhaust systems should be designed independently and used independently.
