WebThe usual pressure range of the application is 0–3 in. water static pressure [62]. The vane axial and tube axial can be selected for higher outlet velocities than the centrifugal, approximately 2,000–4,000 ft/min through the fan casing as compared to 2,000–3,500 (a few to 6,600) ft/min outlet velocity for the centrifugal. WebStatic pressure in fan systems is typically less than 2" SP, or 0.072 Psi. The amount of static pressure that the fan must overcome depends on the air velocity in the ductwork, the number of duct turns (and other resistive elements), and the duct length.
