What size of generator do you need to power 30 kW Air compressor?

To power a 30 kW air compressor, you would typically need a generator with a capacity of at least 37.5 kW to account for starting surges and ensure reliable operation. It's advisable to choose a generator with a higher output, such as 40-50 kW, to provide a safety margin and handle any additional loads. Make sure the generator is compatible with the air compressor's voltage requirements as well.
