The limitations of the existing system in AHU
  1. Belt driven systems which are typical in HVAC applications
  2. The problems with existing fans are the cost of running and maintaining them
  3. Require ongoing maintenance and frequent replacement of belts, pulleys, and bearings
  4. Failure to do so ultimately leads to increased inefficiencies and motor and bearing failures
