The working principle of the NF1300 ductless air purifying fume hood in Yinchuan City is that the top of the ductless fume hood comes with a fan and filter. Turn on the switch and operate the fan to create negative pressure inside the cabinet, ensuring that chemicals do not overflow. The main wind direction is from bottom to top, so that all the air inside the cabinet is filtered through the filter, and the clean air is discharged from the top exhaust outlet. On the one hand, it purifies the chemicals emitted from the cabinet, and on the other hand, the air entering the cabinet in the laboratory can also purify the air inside the laboratory. Installation and debugging are simple and convenient, energy-saving and environmentally friendly, do not consume air conditioning, purify the air in the laboratory, and protect the health of personnel.
