Engineers selecting a blower for a given installation must have detailed knowledge (or at least estimates) of the application’s operating point as well as a plot of the system’s resistance curve; the prospective blower performance in response to speed changes; static and velocity pressure; and required blower life. Consider the first parameter. A blower-system operating point is defined as the intersection of the blower’s performance curve with the installation resistance curve — both plotted on pressure-CFM chart. Therefore, the operating point of a blower depends on two factors: 1) Required CFM flow rate 2) A pressure-change value called head loss...

The innovative design and enhancements of the Windjammer Pro provide increased performance over competitive models. One key feature is the ability to apply multiple performance profiles depending on the application requirement. New to the feature list, “common performance” provides the ability to have the same air performance whether operating at 120 or 240 vac. This is great for OEM products designed for the global market. This model provides 17% greater flow compared to other manufacturers. The Windjammer Pro operates at a lower temperature to extend the life of the brushless motor. Improved motor cooling along with shaft and bearing assembly...
