Two-speed, Two-winding Variable Torque For Belt Driven or Shaft Mounted Fan Applications
Variable torque, two-speed motors are suited for belted or fan on shaft applications. They are self ventilated, and may be mounted within or outside of the driven fan’s air stream.

Resilient mounted for quiet operation, and lubricated with high temperature Exxon POLYREX® EM lubricant.

3/4 HP and larger single phase are capacitor start motors; smaller single phase are split phase start.
