Power requirements depend on the size and type of the compressor – the larger ones will be more efficient. The power demand decreases as the inlet (mains) pressure increases. Some rough figures are inlet pressure 2 bar, specific power (SP) in kW hours per cubic meter will be 0.32 for a small compressor, 0.28 for a large compressor. Inlet 5 bar SP 0.26, 0.22 (for small & large) Inlet 10 bar, 0.22, 0.18. Inlet 15bar, 0.18, 0.14.
