In many heavy-duty equipment applications, centrifugal blowers must perform consistently and reliably over a range of flow at or near constant pressure. Unfortunately, in this situation, conventional centrifugal blowers consistently fall short of reliable performance as a result of surge, which is an instability that develops between the blower and duct system during reduced flows and is generally characterized by periodic pressure fluctuations of 25 percent or more of the blower static pressure. Surge is responsible for a host of problems, including:

· Reduced controllability
· Housing, wheel and foundation cracks
· Failure of inlet and outlet connections
· Unstable system airflow affecting burner pilots, process operations,
flow measuring equipment and vibration detectors
· High, irregular fan noise
