Overspeed testing of the rotor ensures the safety and longevity of the fan by testing the critical component at a higher speed than it would encounter during normal operation. After running the overspeed test, every welded joint and hub attachment hardware is visually inspected to confirm that the fan’s construction can tolerate the high speeds without developing cracks.
Testing fans rotors to higher-than-normal stress provides end users with the confidence that the rotors have been tested at speeds beyond the maximum operating speed—with no observable impact to the structural integrity of the rotor. This provides additional assurance that the fan will operate safely and reliably under normal operating conditions.
