Selection of fume hood fans
Thread Content
The axial flow fan on the outdoor duct of the fume hood is broken; it’s been so long that the model cannot be identified. How should I choose a replacement? What technical parameters are required? How to determine the parameters? The fume hood is 1.5 meters long, 0.8 meters wide, and 2.3 meters high. The duct diameter is 30 centimeters, and the total length of the duct is 12 meters. What if two such fume hoods are connected in series for ventilation? How should the model be selected in that case? Please provide detailed information. Thank you all!
There should be requirements regarding air volume, which needs to be determined by the laboratory itself
