Minimum Flow To Avoid Stall:
x1000 cfm
NOTE:
For forward-curved and axial flow fans, focus point-collection on points outside the region of instability, avoiding points in the "deep valley-portion" of the concave-up section in the unstable region, while ensuring however, that points associated with flow = 0 cfm and flows whose heads are closer to the top section of the head-curve in this region are captured.
