- Voltage: 110,200,208,230,460, 575
- Phase: Single (1) or Three (3)
- Generally air compressors over 7 hp only come in 3 phase.
- 110 is standard voltage for homes, also 110 voltage only has single phase capability and will only run up to a 3hp air compressor.
5. What application will the air compressor be used for? What quality of air will be needed?
