D is the outer diameter of the fan impeller
Axial dimension L > 1.25D for axial air supply,dimension L=0 for radial air supply.
The radial dimension A > 2D in the positivepressure box, the radial dimension B=(A-D)/2
The positive pressure box meets the abovedimensions, and the direction of the air outlet haslittle effect on performance
