Cotta Transmission Company has been manufacturing gearboxes for fan drives for decades.  These speed increasers are being used to run 2 and 3 stage centrifugal fans in sewer cleaning equipment.  This type of application requires a robust gearbox that will not get out of balance from the rocks, dirt and other debris that run through the system during the sewer cleaning process.

Specifications:

  • Ratio: 1 : 2.036
  • Max Input Torque: 625 ft lbs
  • Approximate Weight: 375 lbs
