How to Size VSD Air Compressors

  1. Determine Flow Curve 
  2. For existing installations, it’s always best to perform an audit
  3. For new installations, find out how you plan to run the equipment
  4. Do not guess
  5. Incorrect sizing results in poor performance
  6. Look at the smaller variance in flow
  7. Size your VSD Compressor to be able to match the smaller changes
  8. Use additional compressors to account for large changes
  9. Control Gap where the VSD is not able to match the flow required

Optimal Range of VSD

In general, is 40% -80%
