petrol v electric compressor

[johnzx6]

i have a compressor with a 5.5 hp 3 phase electric
motor and i'm concidering putting a 6 hp petrol
engine on in its place,which do you think would
be cheaper to run hopefully it'll be used all day
every day.

I would say electric would be cheaper to run. After all if it was cheaper to provide 5hp with a generator than draw it from the mains every house would have its own generator.

Also when the tank is full an electric unit would switch off, whereas a petrol engined one would keep ticking over. You also have to consider the higher servicing costs of an engine.

motor driven without doubt cheaper to run

Electric driven unless a diesel engine run on waste oil is used !
