Performance Features and Benefits of the LS TurboShot Indirect Drive Impeller

Why indirect drive impellers instead of direct drive? In one word- MAINTENANCE. The LS belt driven impeller uses
spherical bearings that have a service life many times that of standard sealed bearings. The direct drive impeller
cannot use spherical bearings as it must use oversized sealed bearings to support the weight of the motor and impeller
mechanism.

Additionally, during operation vibration from the impeller is transmitted back up the motor shaft and into the motor causing
premature motor failure. With the LS system the impeller motors are isolated from impeller vibrations extending the
life of the motor. The belt drive system acts as a slip clutch allowing the impeller to stop turning should something block the
impeller’s rotation. With a direct drive wheel this would result in a burned out motor or a tripped overload relay.

Easy maintenance is another factor. The LS impeller can be serviced or completely replaced without removing
the motor. With direct drive systems the motor must be removed any time the impeller or impeller bearings are being serviced.
Almost every component of the LS impeller can be repaired, replaced or maintained using basic hand tools. It is quite simply
the most durable, rugged design available today.

But can indirect or belt driven impellers provide the performance of a direct drive wheel? The LS impeller is capable
of throwing 450 pounds of abrasive per minute. This is over 100 pounds more per minute than a standard direct
drive impeller. More abrasive being thrown means more impact on the parts, a more thorough cleaning pattern, more thorough
coverage and faster production speeds.
