Moore Engine Drive Fans are Class 5000 fans that have been modified for service in engine drive applications. Modifications include ruggedized mounts and clevises and double-riveted blades.
Engine Drive Fans are aerodynamically identical to standard high-efficiency Class 5000 units. They have all of the features shown for under Class 5000 Fan Features with two exceptions:
Fan diameters are not adjustable in the field. They may be specified, however, in increments of 0.01 ft
Engine Drive Fans are provided with manually adjustable blades. Automatic hubs are not suitable for this application.
Three features of Class 5000 fans are of particular interest in engine drive applications:
Low Inertia: The blade forming method provides a blade that is very rigid, yet lighter weight than possible with other methods. This lighter weight results in low blade inertia and lowers the possibility of fan damage in case of sudden emergency stops typical of engine drive operation.
Low stress: The resilient blade mounting reduces the stress transmitted to the fan blades from the motor and drive.
No critical speeds: The floating fan blades keep resonant frequencies always above the rotation speed. There are no critical speeds to be avoided.
Engine Drive Fans are available in the following series and diameters:
