Why does a blower “walk” or move from a stationary position?
Movement from a stationary position or “walking” occurs because of vibration – not the fact that the impellers are pulling/pushing air through the shroud! Direct Drive blowers have a tendency to “walk” if not monitored properly and set up correctly. Direct Drive blowers can also begin to vibrate badly and produce a grinding noise when there is engine shaft bearing wear. However, with the NEW Tempest Air-Flex Impeller, and the improved small engines used by Tempest today, there is less vibration to produce movement and shaft bearing damage. Belt Drive blowers do not “walk”! The belt acts as a buffer for the vibration created by the motor and possible intake air current disturbance to the impeller.
