5 T How to elect a Direct Drive Blower 1. Locate your system characteristics (CFM & P) on the chart with the blower performance curves. 2. Move up the system curve to intersect the closest blower performance curve. That is the performance (CFM & P) that the blower will provide at full speed. 3. Note the CFM. 4. The speed reduction required to operate at the desired CFM is 1 less the ratio of the full speed CFM to the desired CFM. Example: Required in. W.G. (ref. DUB-12 to DUB-30 curves) 1. Locate in. W.G. on the chart (pt. 1). 2. Move up the chart, parallel to the system curves (follow the arrow), to intersect the 1st blower curve (DUB-30). The intersection point, (pt. 2), in W.G. is the performance that the DUB-30 will deliver at full RPM. 3. To deliver the desired 1000 CFM, using the speed controller, reduce the RPM to attain the required 1000 CFM. In this case, the required reduction is 1 - (required CFM / full speed CFM) = 1 - (1000/1175) = 15%.
