Fan Performance. Characteristics of Centrifugal Fans. Vector R represents the resultant velocity for each of these blade shapes. Note that R for the forward curve impeller is the largest with the backward inclined impel- ler the smallest, while the radial blade fan lies some- where in between. This relationship is best illustrated
3. Centrifugal Fan Pressure and Ducting Resistance. 3.1 Conditions to Achieve. Stable Gas Flow. A draft, Q1, forced through a certain ducting is determined by the ducting resistance curve, R, and Fan Pressure. ( = Static Pressure) curve, P. In Figure (3), as indicated by the R-curve, Ducting Resistance is a curve climbing.
The following diagram shows the range of characteristic curves for the most important fan designs and serves as a helpful tool in preselecting a design on the basis of air flow and back pressure.

This type of fan operates stably because the pressure difference provided by the fan drops if the flow rate goes up. If the opposite were true, increased an increased flow rate would cause increase fan power, which is unstable. Fan Curve, Backward-Curved. Centrifugal Blade. TP="total" pressure.

RMD 2501. Centrifugal Fans. R t ti i ll i. i l it. ? Rotating impeller increases air velocity. ? Air speed is converted to pressure. ? High pressures for harsh conditions .. The fan curve is a graphical representation of a number of inter-related parameters under a specific set of conditions. Typically a curve will be developed.
The major types of centrifugal fan are: radial, forward curved and backward curved (see. Figure 5.3). Radial fans are industrial HVAC, various industrial applications, forced draft fans, etc. Vane-axial High pressure, medium flow, dip in pressure-flow curve, use of guide vanes improves efficiency. High pressure applications.
