How to Size VSD Air Compressors
- Determine Flow Curve
- For existing installations, it’s always best to perform an audit
- For new installations, find out how you plan to run the equipment
- Do not guess
- Incorrect sizing results in poor performance
- Look at the smaller variance in flow
- Size your VSD Compressor to be able to match the smaller changes
- Use additional compressors to account for large changes
- Control Gap where the VSD is not able to match the flow required
Optimal Range of VSD
In general, is 40% -80%
