Fan curve explanation

WebThe airflow and static pressure values under the fan's operating conditions are the points on the curve. Airflow vs. static pressure characteristics, also called P-Q performance curves, show the performance characteristics of … WebAxial fan design. An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate. The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Factors which determine the performance of the ...

Centrifugal fans consist of an impeller in a casing having a spirally shaped contour. The air enters the impeller in an axial direction and is discharged at the impeller outer periphery. The air flow moves along the centrifugal direction (or radial direction). Sometimes centrifugal fans are called radial flow type fans. state of kansas health quest login
