For oblique blades it is recommended to use an appropriate selection chart. Air stream range Q h =100 m 3 /h and vertical range L V0,25 < 2m. Sought after diffuser size. We draw a horizontal line (red) corresponding to Q h =100 m 3 /h until curve intersection L V0,25. Sought after diffuser curve below the curve range, in this case we find Type 500 (black). From the point of intersection leading a horizontal line (blue) we will read a pressure loss on the diffuser (0,7 Pa). November
