How to Calculate the Airflow Depending on the Exhaust Suction Hood?
1:choose the dust extraction hoods type: top suction hoods, side suction hoods and down flow suction hoods, pictures as an example:
2:calculate and measure the size the pictures showed. Then choose the air velocity from the table:
3:at last, choose the Positive coefficient “k”:
4:depending on the formula, we can figure out the air volume.
